Subject: ath10k: htc: made static function public

Changed ath10k_htc_notify_tx_completion and
ath10k_htc_process_trailer from static to non static.

These functions are needed by SDIO/mbox.

Subject: ath10k: htc: rx trailer lookahead support

The RX trailer parsing is now capable of parsing lookahead reports.
A lookahead contains the first 4 bytes of the next HTC message
(that will be read in the next SDIO read operation).
Lookaheads are used by the SDIO/mbox HIF layer to determine if
the next message is part of a bundle, which endpoint it belongs
to and how long it is.

Subject: ath10k: htc: move htc ctrl ep connect to htc_init

This patch moves the HTC ctrl service connect from
htc_wait_target to htc_init.

This is done in order to make sure the htc ctrl service
is setup properly before hif_start is called.

The reason for this is that we want the HTC ctrl service
callback to be initialized before the target sends the
HTC ready message.

The ready message will always be transmitted on endpoint 0
(which is always assigned to the HTC control service) so it
makes more sense if HTC control has been connected before the
ready message is received.

Since the service to pipe mapping is done as a part of
the service connect, the get_default_pipe call is redundant
and was removed.

Subject: ath10k: htc: refactorization

Code refactorization:

Moved the code for ep 0 in ath10k_htc_rx_completion_handler
to ath10k_htc_control_rx_complete.

This eases the implementation of SDIO/mbox significantly since
the ep_rx_complete cb is invoked directly from the SDIO/mbox
hif layer.

Since the ath10k_htc_control_rx_complete already is present
(only containing a warning message) there is no reason for not
using it (instead of having a special case for ep 0 in
ath10k_htc_rx_completion_handler).

Subject: ath10k: htc: ready_ext msg support

Added support for extended ready message.
The extended ready message contains the maximum bundle
count supported by SDIO chipsets.

It is transmitted by SDIO chipset only and replaces the
"standard" ready message in this case.

Subject: ath10k: different fw file name for sdio

Since both SDIO based chipsets will use different
firmware from the PCIe and AHB chipsets, the fw file name
must be different depending on bus type.

The new firmware names are:

For PCIe and AHB:
firmware-<api_version>.bin (same as before)

For SDIO:

Subject: ath10k: add initial SDIO support

Chipsets like QCA6584 have support for SDIO so add initial SDIO bus support to
ath10k. With this patch we have the low level HTC protocol working and it's
possible to boot the firmware, but it's still not possible to connect or
anything like. More changes are needed for full functionality. For that reason
we print during initialisation:

WARNING: ath10k SDIO support is incomplete, don't expect anything to work!

+	 * we know that response data is available.
+	 *
+	 * This allows us to cleanly timeout on an unexpected
+	 * Target failure rather than risk problems at the HIF level.
+	 * In particular, this avoids SDIO timeouts and possibly garbage
+	 * data on some host controllers.  And on an interconnect
+	 * such as Compact Flash (as well as some SDIO masters) which
+	 * does not provide any indication on data timeout, it avoids
+	 * a potential hang or garbage response.
+	 *
+	 * Synchronization is more difficult for reads larger than the
+	 * size of the MBOX FIFO (128B), because the Target is unable
+	 * to push the 129th byte of data until AFTER the Host posts an
+	 * HIF Read and removes some FIFO data.  So for large reads the
+	 * Host proceeds to post an HIF Read BEFORE all the data is
+	 * actually available to read.  Fortunately, large BMI reads do
+	 * not occur in practice -- they're supported for debug/development.
+	 *
+	 * So Host/Target BMI synchronization is divided into these cases:
+	 *  CASE 1: length < 4
+	 *        Should not happen
+	 *
+	 *  CASE 2: 4 <= length <= 128
+	 *        Wait for first 4 bytes to be in FIFO
+	 *        If CONSERVATIVE_BMI_READ is enabled, also wait for
+	 *        a BMI command credit, which indicates that the ENTIRE
+	 *        response is available in the the FIFO
+	 *
+	 *  CASE 3: length > 128
+	 *        Wait for the first 4 bytes to be in FIFO
+	 *
+	 * For most uses, a small timeout should be sufficient and we will
+	 * usually see a response quickly; but there may be some unusual
+	 * (debug) cases of BMI_EXECUTE where we want an larger timeout.
+	 * For now, we use an unbounded busy loop while waiting for
+	 * BMI_EXECUTE.
+	 *
+	 * If BMI_EXECUTE ever needs to support longer-latency execution,
+	 * especially in production, this code needs to be enhanced to sleep
+	 * and yield.  Also note that BMI_COMMUNICATION_TIMEOUT is currently
+	 * a function of Host processor speed.

Subject: ath10k: fix out of bounds access to local buffer

During write to debugfs file simulate_fw_crash, fixed-size local buffer
'buf' is accessed and modified at index 'count-1', where 'count' is the
size of the write (so potentially out of bounds).
This patch fixes this problem.

Subject: ath10k: append the wmi_op_version to testmode get_version cmd

QCA9xxx and QCA61x4/QCA93xx are using different wmi operation, in order
for userspace to differentiate it, appends the wmi_op_version information
alone with the get_version command.

Subject: {net, IB}/mlx5: Replace mlx5_vzalloc with kvzalloc

Commit a7c3e901a46f ("mm: introduce kv[mz]alloc helpers") added
proper implementation of mlx5_vzalloc function to the MM core.

This made the mlx5_vzalloc function useless, so let's remove it.

This function will be called from FPGA-related logic in a later patch from
asynchronous event (IRQ) context, for that we change the spin lock to an
IRQ-safe one.

Subject: net/mlx5: FPGA, Add basic support for Innova

Mellanox Innova is a NIC with ConnectX and an FPGA on the same
board. The FPGA is a bump-on-the-wire and thus affects operation of
the mlx5_core driver on the ConnectX ASIC.

Add basic support for Innova in mlx5_core.

This allows using the Innova card as a regular NIC, by detecting
the FPGA capability bit, and verifying its load state before
initializing ConnectX interfaces.

Also detect FPGA fatal runtime failures and enter error state if
they ever happen.

All new FPGA-related logic is placed in its own subdirectory 'fpga',
which may be built by selecting CONFIG_MLX5_FPGA.
This prepares for further support of various Innova features in later
patchsets.
Additional details about hardware architecture will be provided as
more features get submitted.

This patch adds statistic counter for frames recovered from HW errata
10GE_8 and ENET_11:
"HW reports Length error for valid 64 byte frames with len <46 bytes".

Subject: drivers: net: xgene: Workaround for HW errata 10GE_10/ENET_15

This patch adds workaround for HW errata 10GE_10 and ENET_15:
"HW statistic counters value are duplicated".

- RFCS duplicates RALN counter
- RFLR duplicates RUND counter
- TFCS duplicates TFRG counter
- RALN should be intepreted as 0 in 10G mode

Subject: drivers: net: xgene: Fix redundant prefetch buffer cleanup

Prefetch buffer cleanup code was called twice, causing EDAC to
report errors during reboot.

error
[ 1130.979584] xgene-edac 78800000.edac: IOB BA write response error

[ 1130.993612] xgene-edac 78800000.edac: IOB BA requestor ID 0x00002400
[ 1131.000242] xgene-edac 78800000.edac: IOB bridge agent (BA) transaction
error
...

This patch fixes the errors by,

- removing the redundant prefetch buffer cleanup from port_ops->shutdown()
- moving port_ops->shutdown() after delete_rings()

Subject: bnxt: add dma mapping attributes

On the SPARC platform we need to use the DMA_ATTR_WEAK_ORDERING attribute
in our Rx path dma mapping in order to get the expected performance out
of the receive path.  Adding it to the Tx path has little effect, so
that's not a part of this patch.

We advertise TSO to the stack but leave it disabled by default.
Make sure it's not only disabled in the netdev features but
also on the device itself.

Subject: nfp: rename l4_offset in struct nfp_net_tx_desc to lso_hdrlen

The l4_offset field referred to by NFD is confusingly named. It is not the
offset of the L4 transport header, but rather the L4 payload.

The LSO2 capability supported by alternative device firmware requires
the actual L4 offset, thus the rename seems prudent.

Subject: nfp: support LSO2 capability

Firmware advertising the LSO2 capability exploits driver provided L3 and L4
offsets in order to avoid parsing packet headers in the TX path. The vlan
field in struct nfp_net_tx_desc is repurposed, making TXVLAN a mutually
exclusive configuration to LSO2.

Subject: nfp: version independent support for chained RSS metadata

ABI version 4 introduced metadata chaining. Using the ABI version to signal
metadata chaining precludes firmware that advertises new capabilities which
rely on prepended metadata from working on older kernels.

Capability bits are thus better suited to signalling the chained metadata
format. A new version of the RSS capability is introduced to distinguish
between the differing metadata formats for ABI versions other than 4.

Subject: nfp: complete the XDP TX ring only when it's full

Since XDP TX ring holds "spare" RX buffers anyway, we don't have to
rush the completion.  We can wait until ring fills up completely
before trying to reclaim buffers.  If RX poll has ended an no
buffer has been queued for XDP TX we have no guarantee we will see
another interrupt, so run the reclaim there as well, to make sure
TX statistics won't become stale.

This should help us reclaim more buffers per single queue controller
register read.

Note that the XDP completion is very trivial, it only adds up
the sizes of transmitted frames for statistics so the latency
spike should be acceptable.  In case user sets the ring sizes
to something crazy, limit the completion to 2k entries.

The check if the ring is empty at the beginning of xdp_complete()
is no longer needed - the callers will perform it.

Subject: nfp: add a helper for wrapping descriptor index

We have a number of places where we calculate the descriptor
index based on a value which may have overflown.  Create a
macro for masking with the ring size.

Subject: nfp: eliminate an if statement in calculation of completed frames

Given that our rings are always a power of 2, we can simplify the
calculation of number of completed TX descriptors by using masking
instead of if statement based on whether the index have wrapped
or not.

Subject: mlxsw: spectrum_router: Reduce scope of router struct

In a similar fashion to previous patch, the router structure
('mlxsw_sp_router') doesn't need to be accessible to anyone, but the
router code located at spectrum_router.c

Make this apparent and reduce its scope by defining it there.

Subject: mlxsw: spectrum_switchdev: Reduce scope of bridge struct

Some attributes in the global chip struct are only relevant for bridge
operation, so encapsulate them in their own struct that isn't exposed to
non-bridge code.

This will also help us later, when we add more bridge-specific
attributes.

Subject: mlxsw: spectrum_router: Move RIFs array to its rightful place

The router interfaces (RIFs) array is of no interest to code outside the
routing realm, so declare it inside the router specific struct instead
of the chip-wide one.

Subject: mlxsw: spectrum_router: Initialize RIFs in a separate function

The router interfaces (RIFs) array is currently initialized together
with the general router configuration. However, in a follow-up patchset
we're going to introduce a common RIF core that will require us to
initialize more RIF constructs, so move the RIF initialization to its
own function.

Subject: mlxsw: spectrum_switchdev: Remove redundant check

Since commit 97c242902c20 ("switchdev: Execute bridge ndos only for
bridge ports") switchdev code checks that port is bridged, so no need to
perform the same check in the driver.

Subject: mlxsw: spectrum_switchdev: Don't batch VLAN operations

switchdev's VLAN object has the ability to describe a range of VLAN IDs,
but this is only used when VLAN operations are done using the SELF flag,
which is something we would like to remove as it allows one to bypass
the bridge driver.

Do VLAN operations on a per-VLAN basis, thereby simplifying the code and
preparing it for refactoring in a follow-up patchset.

Subject: mlxsw: spectrum_switchdev: Don't batch STP operations

Simplify the code by using the common function that sets an STP state
for a Port-VLAN and remove the existing one that tries to batch it for
several VLANs.

This will help us in a follow-up patchset to introduce a unified
infrastructure for bridge ports, regardless if the bridge is VLAN-aware
or not.

Subject: mlxsw: spectrum_switchdev: Don't batch learning operations

We no longer batch VLAN operations, so there's no need to set the
learning state for a range of VLANs.

Use a common function to set the learning state for a Port-VLAN, thereby
making the code saner more receptive for upcoming changes.

Subject: mlxsw: spectrum: Default ports to non-virtual mode

In virtual mode, packets are classified to FIDs based on their ingress
port and VLAN whereas in non-virtual mode only the VLAN is taken into
account.

Currently ports are initialized to use virtual mode due to the presence
of the PVID vPort. However, we're going to transition ports between both
modes based on the FIDs they use and not merely based on the presence on
a VLAN upper. Therefore, during initialization, no mode will be
explicitly set.

Since the Programmer's Reference Manual (PRM) doesn't specify a default,
explicitly set the port to non-virtual mode and later transition the
port between both modes based on the FIDs it uses.

In a follow-up patchset, this step will be moved to the common FID core
where it logically belongs.

Subject: net: dsa: store CPU port pointer in the tree

A dsa_switch_tree instance holds a dsa_switch pointer and a port index
to identify the switch port to which the CPU is attached.

Now that the DSA layer has a dsa_port structure to hold this data, use
it to point the switch CPU port.

This patch simply substitutes s/dst->cpu_switch/dst->cpu_dp->ds/ and
s/dst->cpu_port/dst->cpu_dp->index/.

Subject: liquidio: fix insmod failure when multiple NICs are plugged in

When multiple liquidio NICs are plugged in, the first insmod of the PF
driver succeeds.  But after an rmmod, a subsequent insmod fails.  Reason is
during rmmod, the PF driver resets the Octeon of only one of the NICs; it
neglects to reset the Octeons of the other NICs.

Fix the insmod failure by adding the missing Octeon resets at rmmod.  Keep
a per-NIC refcount that indicates the number of active PFs in a given NIC.
When the refcount goes to zero, then reset the Octeon of that NIC.

Subject: can: m_can: move Message RAM initialization to function

To avoid possible ECC/parity checksum errors when reading an
uninitialized buffer, the entire Message RAM is initialized when probing
the driver. This initialization is done in the same function reading the
Device Tree properties.

This patch moves the RAM initialization to a separate function so it can
be called separately from device initialization from Device Tree.

Subject: can: m_can: make m_can_start and m_can_stop symmetric

This moves clocks gating outside of the m_can_stop function as the
m_can_start function does not (and cannot, at least in current
implementation) ungate clocks. This way, both functions can now be used
symmetrically.

Subject: can: m_can: add deep Suspend/Resume support

This adds Power Management deep Suspend/Resume support for Bosch M_CAN
chip.

When entering deep sleep, the clocks are gated, the interrupts are
disabled. When resuming from deep sleep, the chip needs to be
reinitialized, the clocks ungated and the interrupts enabled.

This patch adds support for Intel Bluetooth device 9460/9560 also known
as Jefferson Peak (JfP). The firmware downloading mechanism is same as
previous generation. So include the new USB product identifier and
whitelist the hardware variant.

Subject: Bluetooth: hci_uart: fix kconfig dependency

We see the following link error with CONFIG_BT_HCIUART=y,
CONFIG_BT_HCIUART_LL=y and CONFIG_SERIAL_DEV_BUS=m:

Fix this by dependig BT_HCIUART_LL on the BT_HCIUART_SERDEV symbol.
This implies a dependency on BT_HCIUART and hci_ll.c is only compiled in
if SERIAl_DEV_BUS is built in or SERIAL_DEV_BUS and BT_HCIUART are
modules.

Subject: Bluetooth: hci_ldisc: Use rwlocking to avoid closing proto races

When HCI_UART_PROTO_READY is in the set state, the Data Link protocol
layer (proto) is bound to the HCI UART driver. This state allows the
registered proto function pointers to be used by the HCI UART driver.

When unbinding (closing) the Data Link protocol layer, the proto
function pointers much be prevented from being used immediately before
running the proto close function pointer. Otherwise, there is a risk
that a proto non-close function pointer is used during or after the
proto close function pointer is used. The consequences are likely to
be a kernel crash because the proto close function pointer will free
resources used in the Data Link protocol layer.

Therefore, add a reader writer lock (rwlock) solution to prevent the
close proto function pointer from running by using write_lock_irqsave()
whilst the other proto function pointers are protected using
read_lock(). This means HCI_UART_PROTO_READY can safely be cleared
in the knowledge that no proto function pointers are running.

When flag HCI_UART_PROTO_READY is put into the clear state,
proto close function pointer can safely be run. Note
flag HCI_UART_PROTO_SET being in the set state prevents the proto
open function pointer from being run so there is no race condition
between proto open and close function pointers.

Subject: mwifiex: initiate card-specific work atomically

The non-atomic test + set is a little awkward here, and it technically
means we might double-schedule work unnecessarily. AFAICT, this is not
really a problem, since the extra "work" will be a no-op (the flag(s)
will be cleared by then), but it's still an anti-pattern.

Rewrite this to use the atomic test_and_set_bit() helper instead.

Subject: rtlwifi: btcoex: Remove 23b 2ant configuration parameter

In file halbtc8723b2ant.c, there are directives that depend on an
undocumented configuration parameter BT_AUTO_REPORT_ONLY_8723B_2ANT
that cannot be set from Kconfig. This parameter is replaced by a
boolean in the main structure used by all routines. It still cannot
be changed dynamically, but it is easier to document.

Routines halbtc8723b2ant_set_bt_auto_report(), and
btc8723b2ant_bt_auto_report() are restored.

In file halbtc8192e2ant.c, there are directives that depend on an
undocumented configuration parameter BT_AUTO_REPORT_ONLY_8192E_2ANT
that cannot be set from Kconfig. This parameter is replaced by a
boolean in the main structure used by all routines. It still cannot

Upon the advice of Realtek, the auto report option is turned on with
this patch.

Routine btc8192e2ant_is_wifi_status_changed() is restored.

Subject: rtlwifi: btcoex: 21a 2ant: refine btc8821a2ant_action_hid_a2dp

For hid a2dp profiling, decrease the bt power because of the distance of
bt is usually short, and do not adjust the wifi duration to a longer
period since it may be interrupted by bt easily, set tdma instead.

Subject: rtlwifi: btcoex: 21a 2ant: add pnp notidy to avoid LPS/IPS mismatch

When driver is going to sleep, it does not leave LPS/IPS, thus the
BTCoex may have mismatch when driver wakes up. To avoid that, BTCoex
needs to clear the IPS/LPS state when it receives a pnp notify, then
it can properly set up the hw when driver wakes up.

Subject: rtlwifi: btcoex: 21a 2ant: run mechanism if status changes or auto
 adjust is set

The driver will periodically ask the coex, and the coex only runs the
mechanism when the status was changed or the auto adjust is set.

If the wifi is leaving ips, re-init the coex mechanisms, and before it is

Subject: rtlwifi: btcoex: 21a 2ant: refine bt info notify to have more
 profilings

We add some profiling combinations when the bt notifies the coex
mechanism to detect more situations and adjust the coex to fit to it.

Also monitor if the wifi is under 5G mode, if so, the signals do net
intefere each other, bt can just ignore it

Subject: rtlwifi: btcoex: 21a 2ant: fix PTA unstable problem when hw init

In the hardware initialisation stage, the PTA circuits may be unstable,
so we reset it after 6 secs to fix the problem.

dis_ver_info_cnt is used to indicate the time after init, and we can set
PTA according to it.

Subject: vhost_net: try batch dequing from skb array

We used to dequeue one skb during recvmsg() from skb_array, this could
be inefficient because of the bad cache utilization and spinlock
touching for each packet. This patch tries to batch them by calling
batch dequeuing helpers explicitly on the exported skb array and pass
the skb back through msg_control for underlayer socket to finish the
userspace copying. Batch dequeuing is also the requirement for more
batching improvement on receive path.

Tests were done by pktgen on tap with XDP1 in guest. Host is Intel(R)
Xeon(R) CPU E5-2650 0 @ 2.00GHz.

rx batch | pps

0   2.25Mpps
1   2.33Mpps (+3.56%)
4   2.33Mpps (+3.56%)
16  2.35Mpps (+4.44%)
64  2.42Mpps (+7.56%) <- Default rx batching
128 2.40Mpps (+6.67%)
256 2.38Mpps (+5.78%)

If there are BT high priority packets, we arrange more time to BT.
To make user experience to  be better, HID and SCO are also seen as
high priority packet exist.

Check BT's status, and record it in field bt_disabled. When BT is disabled,
We do special action called wifi_only.  Also, we move the field from
'struct btc_coexist' to 'struct coex_sta_8723b_1ant'.

Subject: rtlwifi: btcoex: 23b 1ant: check PS state before setting tdma
 duration

For time division multiple access, the wifi and bt take turns to
transmit, but we need to let AP know that wifi is under standby mode by
sending null data to "pretend" entering power saving state using lps
rpwm.

But, the fw does not know if it is the actual power saving mode or just a
fake one to cheat to the AP. Hence, before fw setting the tdma duration,
the fw needs the driver to check the power saving state first.

Subject: net/wan/fsl_ucc_hdlc: call qe_setbrg only for loopback mode

We can't assume that we are always in loopback mode if rx and tx clock
have the same clock source. If we want to use HDLC busmode we also have
the same clock source but we are not in loopback mode. So move the
setting of the baudrate generator after the check for property for the
loopback mode.

Subject: net/wan/fsl_ucc_hdlc: add hdlc-bus support

This adds support for hdlc-bus mode to the fsl_ucc_hdlc driver. This can
be enabled with the "fsl,hdlc-bus" property in the DTS node of the
corresponding ucc.

This aligns the configuration of the UPSMR and GUMR registers to what is
done in our ucc_hdlc driver (that only support hdlc-bus mode) and with
the QuickEngine's documentation for hdlc-bus mode.

GUMR/SYNL is set to AUTO for the busmode as in this case the CD signal
is ignored. The brkpt_support is enabled to set the HBM1 bit in the
CMXUCR register to configure an open-drain connected HDLC bus.

Subject: net: dsa: include switchdev.h only once

DSA drivers and core use switchdev. Include switchdev.h only once, in
the dsa.h public header, so that inclusion in DSA drivers or forward
declarations of switchdev structures in not necessary anymore.

Subject: net: dsa: b53: Add compatible strings for the Cygnus-family BCM11360.

Cygnus is a small family of SoCs, of which we currently have
devicetree for BCM11360 and BCM58300.  The 11360's B53 is mostly the
same as 58xx, just requiring a tiny bit of setup that was previously
missing.

Subject: qed: Utilize FW 8.20.0.0

This pushes qed [and as result, all qed* drivers] into using 8.20.0.0
firmware. The changes are mostly contained in qed with minor changes
to qedi due to some HSI changes.

Content-wise, the firmware contains fixes to various issues exposed
since the release of the previous firmware, including:
 - Corrects iSCSI fast retransmit when data digest is enabled.
 - Stop draining packets when receiving several consecutive PFCs.
 - Prevent possible assertion when consecutively opening/closing
   many connections.
 - Prevent possible assertion due to too long BDQ fetch time.

In addition, the new firmware would allow us to later add iWARP support
in qed and qedr.

This code was duplicated as part of the PCIe FLR code added to this
driver. Let's de-duplicate it to:

 * make things easier to read (mwifiex_pcie_free_buffers() now has a
   corresponding mwifiex_pcie_alloc_buffers())
 * reduce likelihood of bugs
 * make error logging equally verbose
 * save lines of code!

Also drop some of the commentary that isn't really needed.

Subject: mwifiex: fixup error cases in mwifiex_add_virtual_intf()

If we fail to add an interface in mwifiex_add_virtual_intf(), we might
hit a BUG_ON() in the networking code, because we didn't tear things
down properly. Among the problems:

 (a) when failing to allocate workqueues, we fail to unregister the
     netdev before calling free_netdev()
 (b) even if we do try to unregister the netdev, we're still holding the
     rtnl lock, so the device never properly unregistered; we'll be at
     state NETREG_UNREGISTERING, and then hit free_netdev()'s:
	BUG_ON(dev->reg_state != NETREG_UNREGISTERED);
 (c) we're allocating some dependent resources (e.g., DFS workqueues)
     after we've registered the interface; this may or may not cause
     problems, but it's good practice to allocate these before registering
 (d) we're not even trying to unwind anything when mwifiex_send_cmd() or
     mwifiex_sta_init_cmd() fail

To fix these issues, let's:

 * add a stacked set of error handling labels, to keep error handling
   consistent and properly ordered (resolving (a) and (d))
 * move the workqueue allocations before the registration (to resolve
   (c); also resolves (b) by avoiding error cases where we have to
   unregister)

[Incidentally, it's pretty easy to interrupt the alloc_workqueue() in,
e.g., the following:

  iw phy phy0 interface add mlan0 type station

by sending it SIGTERM.]

This bugfix covers commits like commit 7d652034d1a0 ("mwifiex: channel
switch support for mwifiex"), but parts of this bug exist all the way
back to the introduction of dynamic interface handling in commit
93a1df48d224 ("mwifiex: add cfg80211 handlers add/del_virtual_intf").

Subject: mwifiex: Don't release tx_ba_stream_tbl_lock while iterating

Despite the macro list_for_each_entry_safe() having the word "safe" in
the name, it's still not actually safe to release the list spinlock
while iterating over the list.  The "safe" in the macro name actually
only means that it's safe to delete the current entry while iterating
over the list.

Releasing the spinlock while iterating over the list means that someone
else could come in and adjust the list while we don't have the
spinlock.  If they do that it can totally mix up our iteration and fully
corrupt the list.  Later iterating over a corrupted list while holding a
spinlock and having IRQs off can cause all sorts of hard to debug
problems.

As evidenced by the other call to
mwifiex_11n_delete_tx_ba_stream_tbl_entry() in
mwifiex_11n_delete_all_tx_ba_stream_tbl(), it's actually safe to skip
the spinlock release.  Let's do that.

No known problems are fixed by this patch, but it could fix all sorts of
weird problems and it should be very safe.

Subject: mwifiex: Don't release cmd_pending_q_lock while iterating

Just like in the previous patch ("mwifiex: Don't release
tx_ba_stream_tbl_lock while iterating"), in
mwifiex_cancel_all_pending_cmd() we were itearting over a list protected
by a spinlock.  Again, it is not safe to release the spinlock while
iterating.  Don't do it.

Luckily in this case there should be no need to release the spinlock.
This is evidenced by:

1. The only function called while the spinlock was released was
   mwifiex_recycle_cmd_node()
2. Aside from atomic functions (which are safe to call), the only
   function called by mwifiex_recycle_cmd_node() was
   mwifiex_insert_cmd_to_free_q().
3. It can be seen in mwifiex_cancel_pending_scan_cmd() that it's OK to
   call mwifiex_insert_cmd_to_free_q() while holding a different
   spinlock (scan_pending_q_lock), so in general holding a spinlock
   should be OK.
4. It doesn't appear that mwifiex_insert_cmd_to_free_q() has any
   interaction with the cmd_pending_q_lock

No known bugs are fixed with this change, but as with other similar
changes this could fix random list corruption.

Subject: mwifiex: Add locking to mwifiex_11n_delba

The mwifiex_11n_delba() function walked the rx_reorder_tbl_ptr without
holding the lock, which was an obvious violation.

Grab the lock.

NOTE: we hold the lock while calling mwifiex_send_delba().  There's also
several callers in 11n_rxreorder.c that hold the lock and the comments
in the struct sound just like very other list/lock pair -- as if the
lock should definitely be help for all operations like this.

Subject: mwifiex: don't drop lock between list-retrieval / list-deletion

mwifiex_exec_next_cmd() seems to have a classic TOCTOU race, where we
drop the list lock in between retrieving the next command and deleting
it from the list. This potentially leaves room for someone else to also
retrieve / steal this node from the list (e.g.,
mwifiex_cancel_all_pending_cmd()).

Let's keep holding the lock while we do our 'ps_state' sanity checks.
There should be no harm in continuing to hold this lock for a bit more.

Noticed only by code inspection.

Subject: mwifiex: don't leak stashed beacon buffer on reset

When removing or resetting an mwifiex device, we don't remember to free
the saved beacon buffer. Use the (somewhat misleadingly-named)
mwifiex_free_priv() helper to handle this.

Noticed by kmemleak during tests:

echo 1 > /sys/bus/pci/devices/.../reset

unreferenced object 0xffffffc09d034a00 (size 256):

The AR5K_EEPROM_READ macro returns with -EIO if a read error

this by explicitly calling ath5k_hw_nvram_read and exiting on
the via the freebuf label that performs the necessary free'ing

Subject: ath9k: check ah->curchan when updating tx power

When driver fail to reset card ah->curchan value stay NULL. When
later driver try to update tx power it oops by using ah->curchan
(calltrace is shown below).

This problem were reported at various places and for some it was
fixed by making ath9k_hw_chip_reset() do not fail. I have this bug
report on some oldish RHEL kernel with AR9285, however it's hard to
debug where reset fail when kernel OOPS, so I think this patch
should be applied. Hopefully ah->curchan is not used unconditionally
on other places until is initialized on ath9k_config().

Subject: qede: Allow WoL to activate by default

When management firmware declares that the device is WoL-capable,
the default driver behavior would be to allow the management firmware
to take the decision of whether it's actually needed or not.

Problem is ethtool interface doesn't have a 'default' kind
of option, and user would see the interface WoL as disabled,
which doesn't accurately reflect the actual configuration.
More-so, if the user actually wants to explicitly disable WoL he'd have
to first enable it [otherwise ethtool would block the command].

Instead of allowing management to make the decision, enable WoL by
default on all devices capable of it.

Subject: qede: Don't use an internal MAC field

Driver maintains its primary MAC in a private field which
gets updated when ndo_dev_set_mac() gets called.

However, there are flows where the primary MAC of the device can change
without said NDO being called [bond device in TLB mode configuring
slaves' addresses], resulting in a configuration where there's a mismatch
between what's apparent to user [the netdevice's value] and what's
configured in the HW [the private value].

As we don't have any real motivation of maintaining this
private field, simply remove it and start using the netdevice's
field instead.

Subject: qed: Revise alloc/setup/free flow

Re-organize the logic that allocates and frees memory of various
sub-components of the hw-function -

 a. No need to pass pointers to said structure as parameters;
    The internal logic knows exactly where to find/set the data.

 b. Nullify pointers after cleanup to prevent possible errors to
    re-entrant code.

The management firmware HSI contains masks which are already
shifted to their right place, so QED_MFW_SET_FIELD() is clearing
incorrect fields by shifting the mask by the offset.

Luckily, today we set the fields in an incrementing order [so we're
not erasing any previously set fields], but this still needs fixing.

Subject: ibmveth: Support to enable LSO/CSO for Trunk VEA.

Current largesend and checksum offload feature in ibmveth driver,
 - Source VM sends the TCP packets with ip_summed field set as
   CHECKSUM_PARTIAL and TCP pseudo header checksum is placed in
   checksum field
 - CHECKSUM_PARTIAL flag in SKB will enable ibmveth driver to mark
   "no checksum" and "checksum good" bits in transmit buffer descriptor
   before the packet is delivered to pseries PowerVM Hypervisor
 - If ibmveth has largesend capability enabled, transmit buffer descriptors
   are market accordingly before packet is delivered to Hypervisor
   (along with mss value for packets with length > MSS)
 - Destination VM's ibmveth driver receives the packet with "checksum good"
   bit set and so, SKB's ip_summed field is set with CHECKSUM_UNNECESSARY
 - If "largesend" bit was on, mss value is copied from receive descriptor
   into SKB's gso_size and other flags are appropriately set for
   packets > MSS size
 - The packet is now successfully delivered up the stack in destination VM

The offloads described above works fine for TCP communication among VMs in
the same pseries server ( VM A <=> PowerVM Hypervisor <=> VM B )

We are now enabling support for OVS in pseries PowerVM environment. One of
our requirements is to have ibmveth driver configured in "Trunk" mode, when
they are used with OVS. This is because, PowerVM Hypervisor will no more
bridge the packets between VMs, instead the packets are delivered to
IO Server which hosts OVS to bridge them between VMs or to external
networks (flow shown below),
  VM A <=> PowerVM Hypervisor <=> IO Server(OVS) <=> PowerVM Hypervisor
                                                                   <=> VM B
In "IO server" the packet is received by inbound Trunk ibmveth and then
delivered to OVS, which is then bridged to outbound Trunk ibmveth (shown
below),
        Inbound Trunk ibmveth <=> OVS <=> Outbound Trunk ibmveth

In this model, we hit the following issues which impacted the VM
communication performance,

 - Issue 1: ibmveth doesn't support largesend and checksum offload features
   when configured as "Trunk". Driver has explicit checks to prevent
   enabling these offloads.

 - Issue 2: SYN packet drops seen at destination VM. When the packet
   originates, it has CHECKSUM_PARTIAL flag set and as it gets delivered to
   IO server's inbound Trunk ibmveth, on validating "checksum good" bits
   in ibmveth receive routine, SKB's ip_summed field is set with
   CHECKSUM_UNNECESSARY flag. This packet is then bridged by OVS (or Linux
   Bridge) and delivered to outbound Trunk ibmveth. At this point the
   outbound ibmveth transmit routine will not set "no checksum" and
   "checksum good" bits in transmit buffer descriptor, as it does so only
   when the ip_summed field is CHECKSUM_PARTIAL. When this packet gets
   delivered to destination VM, TCP layer receives the packet with checksum
   value of 0 and with no checksum related flags in ip_summed field. This
   leads to packet drops. So, TCP connections never goes through fine.

 - Issue 3: First packet of a TCP connection will be dropped, if there is
   no OVS flow cached in datapath. OVS while trying to identify the flow,
   computes the checksum. The computed checksum will be invalid at the
   receiving end, as ibmveth transmit routine zeroes out the pseudo
   checksum value in the packet. This leads to packet drop.

 - Issue 4: ibmveth driver doesn't have support for SKB's with frag_list.
   When Physical NIC has GRO enabled and when OVS bridges these packets,
   OVS vport send code will end up calling dev_queue_xmit, which in turn
   calls validate_xmit_skb.
   In validate_xmit_skb routine, the larger packets will get segmented into
   MSS sized segments, if SKB has a frag_list and if the driver to which
   they are delivered to doesn't support NETIF_F_FRAGLIST feature.

This patch addresses the above four issues, thereby enabling end to end
largesend and checksum offload support for better performance.

 - Fix for Issue 1 : Remove checks which prevent enabling TCP largesend and
   checksum offloads.
 - Fix for Issue 2 : When ibmveth receives a packet with "checksum good"
   bit set and if its configured in Trunk mode, set appropriate SKB fields
   using skb_partial_csum_set (ip_summed field is set with
   CHECKSUM_PARTIAL)
 - Fix for Issue 3: Recompute the pseudo header checksum before sending the
   SKB up the stack.
 - Fix for Issue 4: Linearize the SKBs with frag_list. Though we end up
   allocating buffers and copying data, this fix gives
   upto 4X throughput increase.

Note: All these fixes need to be dropped together as fixing just one of
them will lead to other issues immediately (especially for Issues 1,2 & 3).

Subject: cxgb4 : retrieve port information from firmware

issue get port information command to firmware to retrieve port
information and update if it is different from what was last
recorded and also add indication for supported link modes for
firmware port types FW_PORT_TYPE_SFP28, FW_PORT_TYPE_KR_SFP28,
FW_PORT_TYPE_CR4_QSFP.

Subject: net: ethernet: update drivers to handle HWTSTAMP_FILTER_NTP_ALL

Include HWTSTAMP_FILTER_NTP_ALL in net_hwtstamp_validate() as a valid
filter and update drivers which can timestamp all packets, or which
explicitly list unsupported filters instead of using a default case, to
handle the filter.

Subject: net: ethernet: update drivers to make both SW and HW TX timestamps

Some drivers were calling the skb_tx_timestamp() function only when
a hardware timestamp was not requested. Now that applications can use
the SOF_TIMESTAMPING_OPT_TX_SWHW option to request both software and
hardware timestamps, the drivers need to be modified to unconditionally
call skb_tx_timestamp().

setup_timer.cocci suggested the following improvement:
drivers/net/wireless/broadcom/brcm80211/brcmfmac/btcoex.c:383:1-11: Use
setup_timer function for function on line 384.

The combination of init_timer and setting up the data and function field
manually is equivalent to calling setup_timer(). This is an api
consolidation only and improves readability.

Subject: brcmfmac: remove setting IBSS mode when stopping AP

Upon stopping an AP interface the driver disable INFRA mode effectively
setting the interface in IBSS mode. However, this may affect other
interfaces running in INFRA mode. For instance, if user creates and stops
hostap daemon on virtual interface, then association cannot work on
primary interface because default BSS has been set to IBSS mode in
firmware side. The IBSS mode should be set when cfg80211 changes the
interface.

Subject: hostap: convert hostap_cmd_queue.usecnt from atomic_t to refcount_t

refcount_t type and corresponding API should be
used instead of atomic_t when the variable is used as
a reference counter. This allows to avoid accidental
refcounter overflows that might lead to use-after-free
situations.

Subject: ray_cs: Avoid reading past end of buffer

Using memcpy() from a buffer that is shorter than the length copied means
the destination buffer is being filled with arbitrary data from the kernel
rodata segment. In this case, the source was made longer, since it did not
match the destination structure size. Additionally removes a needless cast.

This was found with the future CONFIG_FORTIFY_SOURCE feature.

Subject: macsec: double accounting of dropped rx/tx packets

The macsec implementation shouldn't account for rx/tx packets that are
dropped in the netdev framework. The netdev framework itself accounts
for such packets by atomically updating struct net_device`rx_dropped and
struct net_device`tx_dropped fields. Later on when the stats for macsec
link is retrieved, the packets dropped in netdev framework will be
included in dev_get_stats() after calling macsec.c`macsec_get_stats64()

struct nfp_net represents a vNIC, we will be moving away from the

Remove "netdev" from some function names and prefer passing
struct nfp_net pointer as argument instead of struct net_device *.

From d4e7f0928593ac7df9b78410beb90178326a22c0 Mon Sep 17 00:00:00 2001
From: Jakub Kicinski <jakub.kicinski@netronome.com>
Date: Mon, 22 May 2017 10:59:24 -0700
Subject: nfp: rename netdev/port to vNIC

vNIC is a PCIe-side abstraction NFP firmwares supported by this
driver use.  It was initially meant to represent a device port
and therefore a netdev but today should be thought of as a way
of grouping descriptor rings and associated state.  Advanced apps
will have vNICs without netdevs and ports without a vNIC (using
representors instead).

Make sure code refers to vNICs as vNICs and not ports or netdevs.
No functional changes.

Subject: nfp: add nfp_net_pf_free_vnic() function

Soon a third place will need to free a struct nfp_net.  Add a free
counterpart to nfp_net_pf_alloc_vnic().

Subject: nfp: introduce very minimal nfp_app

Introduce a concept of an application.  For now it's just grouping
pointers and serving as a layer of indirection.  It will help us
weaken the dependency on nfp_net in ethtool code.  Later series
will flesh out support for different apps in the driver.

Subject: nfp: disallow mixing vNICs with and without NSP port entry

We only support core NIC apps which have vNICs for each physical port/
split and no representors right now.  Enforce that either each vNIC has
a NSP eth_table entry or if NSP port table is not available none do.

One scenario this will prevent from happening is user force-loading
wrong firmware file if FW app requires different firmwares per media
config.

While at it move some code to nfp_net_pf_alloc_vnic() to make it
counter-match nfp_net_pf_free_vnic() better.

Subject: nfp: introduce nfp_port

Encapsulate port information into struct nfp_port.  nfp_port will
soon be extended to contain devlink_port information.  It also makes
it easier to reuse port-related code between vNICs and representors.

Subject: nfp: update port state in place

Always updating port state in place by overriding values in exiting
pf->eth_tbl makes things easier to manage and allows us to have a
common helper for both full and per-port refresh.

Add link to nfp_ports to make it possible to iterate over all ports.
This will come in handy when some ports may be representors.

Subject: nfp: mark port state as stale after reconfig

After port configuration is performed mark it as changed. This
will close a window of time between configuration and async
state refresh which runs from a workqueue where old port state
would be reported.

Subject: nfp: mark port state as stale if update failed

If reading new state of the port failed, mark the port back as CHANGED.
This way next user state request will trigger refresh, which will
hopefully succeed.

Subject: Bluetooth: hci_ll: Fix download_firmware() return when __hci_cmd_sync
 fails

When __hci_cmd_sync() fails, download_firmware() should also fail, and
the same error value should be returned as PTR_ERR(skb).

Without this fix, download_firmware() will return a success when it actually
failed in __hci_cmd_sync().

Subject: enic: unmask intr only when napi is complete

In case of busy poll, napi_complete_done returns false and does not
dequeue napi. In this case do not unmask the intr. We are guaranteed
napi is called again. This reduces unnecessary iowrites.

Subject: ath10k: fix reported HT MCS rates with NSS > 1

The QCA4019 firmware 10.4-3.2.1-00050 reports only HT MCS rates between
0-9. But 802.11n MCS rates can be larger than that. For example a 2x2
device can send with up to MCS 15.

The firmware encodes the higher MCS rates using the NSS field. The actual
calculation is not documented by QCA but it seems like the NSS field can be
mapped for HT rates to following MCS offsets:

 * NSS 1: 0
 * NSS 2: 8
 * NSS 3: 16
 * NSS 4: 24

This offset therefore has to be added for HT rates before they are stored
in the rate_info struct.

Subject: wil6210: low level RF sector API

Added vendor commands for low level control over
RF sectors. It allows user space a fine-grained control
over RF characteristics for TX and RX, such as direction
and gain of TX/RX. Main usages are debugging and diagnostics,
but also operational use cases.
API includes getting/setting a specific RF sector
configuration, as well as getting/setting the selected
sector which is used to communicate with a station.

Subject: rsi: Rename file rsi_91x_pkt.c to rsi_91x_hal.c

The file rsi_91x_hal.c is going to contain device specific code i.e new
firmware loading method for RS9113 chipset. As the file rsi_91x_pkt.c
contains code to prepare device specific descriptors for transmit packet,
this file is renamed to rsi_91x_hal.c which is more relevant as per it's
functionality.

Subject: rsi: Handle usb multi-byte write failure case properly

In function usb_write_register_multiple, if any intermediate block transfer
is failed, further operations should be terminated. 'else' is removed, as
there is no significance for it after return.

Host interface opearation master_reg_read, master_reg_write and
load_data_master_write are added. These functions are needed for the
new firmware loading method. As part of this, the function
master_access_msword is moved from rsi_91x_sdio_ops.c to rsi_91x_sdio.c.

Subject: rsi: Add new firmware loading method

The older firmware loading method has been deprecated and not in use
for any chipets. New method is introduced which works based on soft
boot loader. In this method, complete RAM image and FLASH image are
present in the flash. Before loading the functional firmware, host
issues boot loader commands to verify whether firmware to load is
different from the current functional firmware. If not, firmware
upgrade progresses and boot loader will switch to the new functional
firmware.

"rs9113_wlan_qspi.rps" is the firmware filename used in this patch.

Subject: rsi: Remove old firmware loading method

The older firmware loading method is not usable by any Redpine chipset.
Hence removing that part of the code. Older firmware image with
rsi_91x.fw name is deprecated

Subject: wlcore: fix 64K page support

In the stable linux-3.16 branch, I ran into a warning in the
wlcore driver:

drivers/net/wireless/ti/wlcore/spi.c: In function 'wl12xx_spi_raw_write':
drivers/net/wireless/ti/wlcore/spi.c:315:1: error: the frame size of 12848 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]

Newer kernels no longer show the warning, but the bug is still there,
as the allocation is based on the CPU page size rather than the
actual capabilities of the hardware.

This replaces the PAGE_SIZE macro with the SZ_4K macro, i.e. 4096 bytes
per buffer.

Subject: iwlegacy: warn when enabling power save

iwlegacy firmware can crash when power save is configured. PS was
allowed in "dbdac2b iwlegacy: properly enable power saving" with belive
that user who enable PS is aware of that and can relate firmware crahes
with PS. However some distributions seems to enable PS without user
intervention, so warn about that.

Subject: libertas: Avoid reading past end of buffer

Using memcpy() from a string that is shorter than the length copied means
the destination buffer is being filled with arbitrary data from the kernel
rodata segment. Instead, redefine the stat strings to be ETH_GSTRING_LEN
sizes, like other drivers. This lets us use a single memcpy that does not
leak rodata contents. Additionally adjust indentation to keep checkpatch.pl
happy.

This was found with the future CONFIG_FORTIFY_SOURCE feature.

Subject: rt2x00: change function pointers for register accessors

This prepares the driver for changing all the 'read' register accessors
to return the value instead of passing it by reference. Since a lot
of them are used in callbacks, this takes care of the callbacks first,
adding a couple of helpers that will be removed again one at a time.

Subject: rt2x00: convert rt2800_rfcsr_read return type

With CONFIG_KASAN enabled and gcc-7, we get a warning about rather high
stack usage (with a private patch set I have to turn on this warning,
which I intend to get into the next kernel release):

wireless/ralink/rt2x00/rt2800lib.c: In function 'rt2800_bw_filter_calibration':
wireless/ralink/rt2x00/rt2800lib.c:7990:1: error: the frame size of 2144 bytes is larger than 1536 bytes [-Werror=frame-larger-than=]

The problem is that KASAN inserts a redzone around each local variable
that gets passed by reference, and the newly added function has a lot
of them.

This is a semi-automated conversion to change rt2800_rfcsr_read to return
the register contents instead of passing them by value, resulting in
much better object code. The majority of the patch was done using:

sed -i 's:\(rt2800_rfcsr_read(.*, .*\), &\(.*\));:\2 = \1);:' \
    -i 's:\(rt2800_rfcsr_read_bank(.*, .*\), &\(.*\));:\2 = \1);:' \
        drivers/net/wireless/ralink/rt2x00/rt2800lib.c

From aea8baa10ac5e9acddf80e48593fe85c22d19286 Mon Sep 17 00:00:00 2001

Subject: rt2x00: convert rt2x00_rf_read return type

This is a semi-automated conversion to change rt2x00_rf_read()
to return the register contents instead of passing them by value,
resulting in much better object code. The majority of the patch
was done using:

sed -i 's:\(\<rt2x00_rf_read\>(.*, .*\), &\(.*\));:\2 = \1);:' \
	drivers/net/wireless/ralink/rt2x00/rt*

From 3954b4e30609ffade5eca3c13eab2fd70c76b44e Mon Sep 17 00:00:00 2001
From: Arnd Bergmann <arnd@arndb.de>
Date: Wed, 17 May 2017 16:46:56 +0200
Subject: rt2x00: convert rt2x00mmio_register_read return type

This is a semi-automated conversion to change rt2x00mmio_register_read
to return the register contents instead of passing them by value,
resulting in much better object code. The majority of the patch
was done using:

sed -i 's:\(rt2x00mmio_register_read(.*, .*\), &\(.*\));:\2 = \1);:' \
    -i 's:_rt2x00mmio_register_read:rt2x00mmio_register_read:' \
	drivers/net/wireless/ralink/rt2x00/*.c

The function itself was modified manually along with the one remaining
caller that was not covered automatically.

Subject: rt2x00: convert rt2x00usb_register_read return type

This is a semi-automated conversion to change rt2x00usb_register_read
to return the register contents instead of passing them by value,
resulting in much better object code. The majority of the patch
was done using:

sed -i 's:\(\<rt2x00usb_register_read\>(.*, .*\), &\(.*\));:\2 = \1);:' \
    -i 's:\(\<rt2500usb_register_read\>(.*, .*\), &\(.*\));:\2 = \1);:' \
    -i 's:\(\<rt2500usb_register_read_lock\>(.*, .*\), &\(.*\));:\2 = \1);:' \

From eebd68e7824bae9c6ee637f43d3048f8d459dc1e Mon Sep 17 00:00:00 2001
From: Arnd Bergmann <arnd@arndb.de>

Subject: rt2x00: convert rt2800_register_read return type

This is a semi-automated conversion to change rt2800_register_read
to return the register contents instead of passing them by value,
resulting in much better object code. The majority of the patch
was done using:

sed -i 's:\(rt2800_register_read(.*, .*\), &\(.*\));:\2 = \1);:' \
       's:\(rt2800_register_read_lock(.*, .*\), &\(.*\));:\2 = \1);:' \
	drivers/net/wireless/ralink/rt2x00/rt2800lib.c

The function itself was modified manually along with the one remaining
multi-line caller that was not covered automatically and the indirect
reference.

From 5fbbe378890fd543a9374ec0f86c9cba6d700712 Mon Sep 17 00:00:00 2001

Subject: rt2x00: convert rt2*_bbp_read return type

This is a semi-automated conversion to change *_bbp_read()
to return the register contents instead of passing them by value,
resulting in much better object code. The majority of the patch
was done using:

sed -i 's:\(\<rt.*_bbp_read\>(.*, .*\), &\(.*\));:\2 = \1);:' \
    -i 's:\(\<rt.*_bbp_dcoc_read\>(.*, .*\), &\(.*\));:\2 = \1);:' \
    -i 's:= _\(rt.*_bbp_read\):\1:' drivers/net/wireless/ralink/rt2x00/*

Subject: rt2x00: convert rt2x00_eeprom_read return type

This is a semi-automated conversion to change rt2x00_eeprom_read()
to return the register contents instead of passing them by value,
resulting in much better object code. The majority of the patch
was done using:

sed -i 's:\(\<rt2x00_eeprom_read\>(.*, .*\), &\(.*\));:\2 = \1);:' \
   -i 's:= _\(rt2x00_eeprom_read\):= \1:' drivers/net/wireless/ralink/rt2x00/*

From 5c6a25855cbd057f361c51d98b763eef28175b0b Mon Sep 17 00:00:00 2001

Subject: rt2x00: convert rt2800_eeprom_read return type

This is a semi-automated conversion to change rt2800_eeprom_read to return
the register contents instead of passing them by value, resulting in
much better object code. The majority of the patch was done using:

sed -i 's:\(\<rt2800_eeprom_read\(_from_array\|\)\>(.*, .*\), &\(.*\));:\3 = \1);:'
	drivers/net/wireless/ralink/rt2x00/rt2800lib.c

Some manual tweaking was required here to work around the line wraps.

Subject: rt2x00: convert rt2x00_desc_read return type

This is a semi-automated conversion to change rt2x00_desc_read to return
the register contents instead of passing them by value, resulting in
much better object code. The majority of the patch was done using:

sed -i 's:\(\<rt2x00_desc_read\>(.*, .*\), &\(.*\));:\2 = \1);:' \
    -i 's:\(\<_rt2x00_desc_read\>(.*, .*\), &\(.*\));:\2 = \1);:' \

Subject: rtlwifi: btcoex: 23b 1ant: adjust wifi duration for bt a2dp

The larger the bt a2dp bit pool is, the more time bt needs to receive
them. If we do not adjust the wifi duration, the voice quality will be
low. Hence we reduce the time that wifi holds, to improve the a2dp
service.

If the bt is slave, it may receive a packet at any time, so we
need to mark them as high priority packets in case of packet loss

Subject: rtlwifi: btcoex: 23b 1ant: check more cases when bt is queing

If bt is queing, we need to set the packet priority properly.
Originally we only consider if wifi was connected or not, but now we
also consider if bt is under abnormal scan or wifi is scanning, roaming
or linking, and set the coex table.

Subject: rtlwifi: btcoex: 23b 1ant: turn off ps and tdma mechanism when
 concurrent mode

When wifi is under concurrent mode, we can not distinguish if it is the
real PS or just a fake one by sending null data, so we turn it off
in case of miracast scenario.

Subject: qtnfmac: introduce new FullMAC driver for Quantenna chipsets

This patch adds support for new FullMAC WiFi driver for Quantenna
QSR10G chipsets.

QSR10G (aka Pearl) is Quantenna's 8x8, 160M, 11ac offering.
QSR10G supports 2 simultaneous WMACs - one 5G and one 2G.
5G WMAC supports 160M, 8x8 configuration. FW supports
up to 8 concurrent virtual interfaces on each WMAC.

Patch introduces 2 new drivers:
- qtnfmac.ko for interfacing with kernel wireless core
- qtnfmac_pearl_pcie.ko for interfacing with hardware over PCIe interface

Subject: qed: Flush slowpath tasklet on stop

Today, driver has a synchronization point while closing
the device which synchronizes its slowpath interrupt line.
However, that's insufficient as that ISR would schedule the
slowpath-tasklet - so even after ISR is over it's possible the
handling of the interrupt has not completed.

By doing a disable/enable on the taskelt we guarantee that all
HW events that should no longer be genereated from that point
onward in the flow are truly behind us.

Subject: qed: Replace set_id() api with set_name()

Current API between qed and protocol modules allows passing an
additional private string - but it doesn't get utilized by qed
anywhere.

Clarify the API by removing it and renaming it 'set_name'.

Subject: net: phy: put genphy_config_init's EXPORT_SYMBOL directly after the
 function
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Commit af6b6967d6e1 ("net: phy: export genphy_config_init()") introduced
this EXPORT_SYMBOL and put it after gen10g_soft_reset() instead of
directly after genphy_config_init. Probably this happend when the patch
was applied because http://patchwork.ozlabs.org/patch/339622/ looks ok.

Subject: net: jme: Remove unused functions

The functions jme_restart_tx_engine(), jme_pause_rx() and
jme_resume_rx() are not used. Removing them fixes the following warnings
when building with clang:

Subject: net-next: stmmac: rework the speed selection

The current stmmac_adjust_link() part which handle speed have
some if (has_platform) code and my dwmac-sun8i will add more of them.

So we need to handle better speed selection.
Moreover the struct link member speed and port are hard to guess their
purpose. And their unique usage are to be combined for writing speed.

So this patch replace speed/port by simpler
speed10/speed100/speed1000/speed_mask variables.

In dwmac4_core_init and dwmac1000_core_init, port/speed value was used
directly without using the struct link. This patch convert also their
usage to speedxxx.

Subject: be2net: Fix UE detection logic for BE3

On certain platforms BE3 chips may indicate spurious UEs (unrecoverable
error). Because of the UE detection logic was disabled in the driver
for BE3 chips. Because of this, even in cases of a real UE,
a failover will not occur. This patch re-enables UE detection on BE3
and if a UE is detected, reads the POST register. If the POST register,
reports either a FAT_LOG_STATE or a ARMFW_UE, then it means that a valid
UE occurred in the chip.

Subject: Add the mlxfw module for Mellanox firmware flash process

The mlxfw module is in charge of common logic needed to flash Mellanox
devices firmware, which consists of:
 - Parse the Mellanox Firmware Archive version 2 (MFA2) format, which is
   the format used to store the Mellanox firmware. The MFA2 format file can
   hold firmware for many different silicon variants, differentiated by a
   unique ID called PSID. In addition, the MFA2 file data section is
   compressed using xz compression to save both file-system space and
   memory at extraction time.
 - Implement the firmware flash state machine logic, which is a common
   logic for Mellanox products needed to flash the firmware to the device.

As the module is shared between different Mellanox products, it defines a
set of callbacks to be implemented by the specific driver for hardware
interaction.

Subject: mlxsw: spectrum: Add the needed callbacks for mlxfw integration

The mlxfw module defines several needed callbacks in order to flash the
device's firmware. As the mlxfw module is shared between several different
drivers, those callbacks are the glue functionality that is responsible
for hardware interaction. Add those callbacks using the MCQI, MCC, MCDA
registers.

Subject: mlxsw: spectrum: Validate firmware revision on init

Make the spectrum module check the current device firmware version, and if
it is below the supported version, use the libfirmware API to request a
firmware file with the supported firmware version and flash it to the
device using the mlxfw module.

The firmware file names are expected to be of Mellanox Firmware Archive
version 2 (MFA2) format and their name are expected to be in the following
pattern: "mlxsw_spectrum-<major>.<minor>.<sub-minor>.mfa2".

Subject: mlxsw: spectrum_router: Adjust RIF configuration for new firmware
 versions

In new firmware versions, when configuring a {Port, VID} as a router
interface, the driver is responsible for enabling the STP filter and
disabling learning.  Otherwise, packets are discarded.

This change doesn't break existing firmware versions, but is required
for newer firmware versions.

Subject: nfp: move mutex init out of net code

Move mutex init to main file close to structure allocation.
This will allow mutex to be taken before net code runs (e.g.
from devlink callbacks).  While at it remember to destroy
the mutex.

Subject: nfp: add devlink support

Add initial devlink support.  This patch simply switches allocation
of per-adapter structure to devlink's priv and register devlink
with empty ops table.  See following patches for implementation
of particular ops.

We should now clear the app pointer on exit, this is how devlink
callbacks will know app is not initialized.

Subject: nfp: calculate total port lanes for split

For port splitting we will need to know the total number of lanes
in a port.  Calculate that based on eth_table information.

Add support for configuring port split with devlink.  Add devlink
callbacks to validate requested config and call NSP helpers.
Getting the right nfp_port structure can be done with simple iteration.

Subject: net: phy: Create sysfs reciprocal links for attached_dev/phydev

There is currently no way for a program scanning /sys to know whether a
network device is attached to a particular PHY device, just like the PHY
device is not pointed back to its attached network device.

Create a symbolic link in the network device's namespace named "phydev"
which points to the PHY device and create a symbolic link in the PHY
device's namespace named "attached_dev" that points back to the network
device. These links are set up during phy_attach_direct() and removed
during phy_detach() for symetry.

Subject: liquidio: fix rare pci_driver.probe failure of VF driver

There's a rare pci_driver.probe failure of the VF driver that's caused by
PF/VF handshake going out of sync.  The culprit is octeon_mbox_write() who
ignores an ack timeout condition; it just keeps unconditionally writing all
elements of mbox_cmd->data[] even when the other side is not ready for
them.  Fix it by making each write of mbox_cmd->data[i] conditional to
having previously received an ack.

Also fix the octeon_mbox_state enum such that each state gets a unique
value.  Also add ULL suffix to numeric literals in macro definitions.

Subject: liquidio: fix inaccurate count of napi-processed rx packets reported
 to Octeon

lio_enable_irq (called by napi poll) is reporting to Octeon an inaccurate
count of processed rx packets causing Octeon to eventually stop forwarding
packets to the host.  Fix it by using this formula for an accurate count:

    processed rx packets = droq->pkt_count - droq->pkts_pending

Also increase SOFT_COMMAND_BUFFER_SIZE to match what the firmware expects.

Subject: net: dsa: mv88e6xxx: Refactor mv88e6352 SERDES code into an op

The mv88e6390 family has a different SERDES implementation. Refactor
the mv88e6352 code into an ops function, so we can later add the
mv88e6390 code.

Now that we use an op for SERDES operations, we don't need a flag for
it. Remove it.

Subject: net: dsa: mv88e6xxx: mv88e6390X SERDES support

The mv88e6390X family has 8 SERDES lanes. These can be used for 2
10Gbps ports, ports 9 or 10. If these ports are used at slower speeds,
the SERDES lanes become available for other ports for 1000Base-X.

Subject: dsa: mv88e6xxx: Enable/Disable SERDES on port enable/disable

Implement the port enable/disable callbacks, which enable/disable the
SERDES interfaces, if applicable. This should save a bit of
power/heat.

We also need to enable SERDES on CPU and DSA ports, so keep the
existing call to the op, but make it conditional.

Subject: mlxsw: spectrum: Set port's mode according to FID mappings

We currently transition the port to "Virtual mode" upon the creation of
its first VLAN upper, as we need to classify incoming packets to a FID
using {Port, VID} and not only the VID.

However, it's more appropriate to transition the port to this mode when
the {Port, VID} are actually mapped to a FID. Either during the
enslavement of the VLAN upper to a VLAN-unaware bridge or the
configuration of a router port.

Do this change now in preparation for the introduction of the FID core,
where this operation will be encapsulated.

To prevent regressions, this patch also explicitly configures an OVS
slave to "Virtual mode". Otherwise, a packet that didn't hit an ACL rule
could be classified to an existing FID based on a global VID-to-FID
mapping, thus not incurring a FID mis-classification, which would
otherwise trap the packet to the CPU to be processed by the OVS daemon.

Subject: mlxsw: spectrum: Introduce Port-VLAN structure

This is the first step in the transition from the vPort model to a
unified Port-VLAN structure. The new structure is defined and created /
destroyed upon invocation of the 8021q ndos, but it's not actually used
throughout the code.

Subsequent patches will initialize it correctly and also create /
destroy it upon switchdev's VLAN object.

Subject: mlxsw: spectrum: Change signature of FID leave function

When a vPort is destroyed, it leaves the FID it's currently mapped to
(if any) and drops the reference. The FID's leave function expects to
get the vPort as its argument, but this will have to change when the
vPort model is retired.

Change the function signature to expect a Port-VLAN struct instead and
patch the call sites accordingly.

The code introduced in this patch will be removed later in the patchset,
but this intermediary step is required in order to ease the code review.

Subject: mlxsw: spectrum_router: Replace vPorts with Port-VLAN

We're going to get rid of vPorts completely later in the patchset, but
the router code is self-contained, so it's a good candidate to start the
transition with.

Convert all the functions that expects to operate on a vPort to operate
on a Port-VLAN instead.

Subject: mlxsw: spectrum: Don't lose bridge port device during enslavement

Currently, when port netdevs (or their uppers) are enslaved to a bridge,
we simply propagate the CHANGEUPPER event all the way down and lose the
context of the actual netdevice used as the bridge port.

This leads to a lot of information hanging off the ports (and vPorts),
which doesn't logically belong there, such as mrouter indication and
unknown unicast flood state.

Following patches are going to put the mlxsw_sp_port struct on diet and
instead introduce a bridge port struct, where the above mentioned
information belongs. But in order to do that, we need to be able to
determine the bridge port netdevice, so propagate it down.

Subject: mlxsw: spectrum: Don't create FIDs upon creation of VLAN uppers

Up until now we used to create FIDs upon the creation of VLAN uppers on
top of the VLAN-aware bridge. This was done so that in case a router
interface (RIF) was configured on top of the bridge, the FID would
already be there.

Instead, simplify the code and only create the FID upon RIF creation.

This is an intermediary step towards the introduction of the common FID
core, in which this code would be completely removed.

Subject: mlxsw: spectrum: Replace vPorts with Port-VLAN

As explained in the cover letter, since the introduction of the bridge
offload in the mlxsw driver, information related to the offloaded bridge
and bridge ports was stored in the individual port struct,
mlxsw_sp_port.

This lead to a bloated struct storing both physical properties of the
port (e.g., autoneg status) as well as logical properties of an upper
bridge port (e.g., learning, mrouter indication). While this might work
well for simple devices, it proved to be hard to extend when stacked
devices were taken into account and more advanced use-cases (e.g., IGMP
snooping) considered.

This patch removes the excess information from the above struct and
instead stores it in more appropriate structs that represent the bridge
port, the bridge itself and a VLAN configured on the bridge port.

The membership of a port in a bridge is denoted using the Port-VLAN
struct, which points to the bridge port and also member in the bridge
VLAN group of the VLAN it represents. This allows us to completely
remove the vPort abstraction and consolidate many of the code paths
relating to VLAN-aware and unaware bridges.

Note that the FID / vFID code is currently duplicated, but this will
soon go away when the common FID core will be introduced.

Subject: mlxsw: spectrum_router: Allocate FID prior to RIF configuration

The following patches are going to re-arrange the FID and RIF code, so
that when the RIF is configured to the device based on the information
present in the RIF struct (which points to a FID).

For this reason, move the FID allocation to just before the RIF
configuration.

Subject: mlxsw: spectrum_router: Allocate RIF prior to its configuration

In the following patches the RIF's configuration function is going to
expect a RIF struct with all the necessary information.

Therefore, allocate the RIF just before it's configured to the device.

Subject: mlxsw: spectrum_router: Extend the RIF struct

Currently, when a Subport RIF is configured, the LAG status and VLAN of
the underlying port are read from the port itself. This is problematic,
as we would like to have common code to configure all types of RIFs,
which aren't necessarily bound to a port.

Instead, embed the RIF in a struct specific to the Subport type, which
contains all the necessary information.

Subject: mlxsw: spectrum_router: Configure RIFs based on RIF struct

All the information necessary for the configuration of RIFs can now be
found in the RIF struct itself, so reduce the arguments list.

This gets us one step closer to the common RIF core.

Subject: mlxsw: spectrum_router: Flood packets to router after RIF creation

If a packet ingress the router but can't be assigned an ingress RIF,
it's dropped.

Therefore, in the case of RIF configured on top of a bridge, it makes
sense to start flooding broadcast packets to the router only after the
RIF was created.

All RIF types are associated with a virtual router (VR), so determine VR
first when creating a RIF.

That way, we can more easily integrate the common RIF core in the
following patches.

Subject: mlxsw: spectrum: Implement common FID core

The device supports three types of FIDs. 802.1Q and 802.1D FIDs for
VLAN-aware and VLAN-unaware bridges (respectively) and rFIDs to
transport packets to the router block.

The different users (e.g., bridge, router, ACLs) of the FIDs
infrastructure need not know about the internal FIDs implementation and
can therefore interact with it using a restricted set of exported
functions.

By encapsulating the entire FID logic and hiding it from the rest of the
driver we get a code base that it much simpler and easier to work with
and extend.

For example, in the current Spectrum ASIC only 802.1D FIDs can be
assigned a VNI, but future ASICs will also support 802.1Q FIDs. With
this patch in place, support for future ASICs can be easily added by
implementing a new FID operations according to their capabilities.

Subject: mlxsw: spectrum_router: Implement common RIF core

The mlxsw driver currently implements three types of RIFs. VLAN and FID
RIFs for L3 interfaces on top of VLAN-aware and VLAN-unaware bridges
(respectively) and Subport RIFs for all other L3 interfaces.

All the RIF types follow a common configuration procedure, which only
differs in the type-specific bits. The patch exploits this fact and
consolidates the common code paths, thereby simplifying the code and
making it more extensible.

This work also prepares the driver for use with future ASICs, where the
range of the Subport RIFs will be extended and their configuration
modified accordingly. By merely implementing a new RIF operations and
selecting it during initialization, the same driver could be re-used.

Track the state of ibmvnic napis. The driver can get into states where it
can be reset when napis are already disabled and attempting to disable them
again will cause the driver to hang.

A race condition occurs when closing the driver. Free'ing of skb's

this we move the claenup of tx pools during close to after the
sub-CRQ interrupts are disabled.

Subject: bonding: Prevent duplicate userspace notification

Whenever a user changes bonding options, a NETDEV_CHANGEINFODATA
notificatin is generated which results in a rtnelink message to
be sent.  While runnig 'ip monitor', we can actually see 2 messages,
one a result of the event, and the other a result of state change
that is generated bo netdev_state_change().  However, this is not
always the case. If bonding changes were done via sysfs or ifenslave
(old ioctl interface), then only 1 message is seen.

This patch removes duplicate messages in the case of using netlink
to configure bonding.  It introduceds a separte function that
triggers a netdev event and uses that function in the syfs and ioctl
cases.

This was discovered while auditing all the different envents and
continues the effort of cleaning up duplicated netlink messages.

mv88e6xxx_serdes_power returns an error, so no need to print an error
message inside of it. Rather print it in its caller when the error is
ignored, which is in the mv88e6xxx_port_disable void function.

Catch and return its error in the counterpart mv88e6xxx_port_enable.

Subject: net: phy: Relax error checking on sysfs_create_link()

Some Ethernet drivers will attach/connect to a PHY device before calling
register_netdevice() which is responsible for calling netdev_register_kobject()
which would do the network device's kobject initialization. In such a case,
sysfs_create_link() would return -ENOENT because the network device's kobject
is not ready yet, and we would fail to connect to the PHY device.

In order to keep things simple and symetrical, we just take the success path as
indicative of the ability to access the network device's kobject, and create
the second link if that's the case.

Subject: nfp: set driver VF limit

PCI subsystem has support for drivers limiting the number of VFs
available below what the IOV capability claims.  Make use of it.

While at it remove the #ifdef/#endif on CONFIG_PCI_IOV, it was
there to avoid unnecessary warnings in case device read failed
but kernel doesn't have SR-IOV support anyway.  Device reads
should not fail.

Note that we still need the driver-internal check for the case
where max VFs is 0 since PCI subsystem treats 0 as limit not set.

Subject: nfp: don't set aux pointers if ioremap failed

If ioremap of PCIe ctrl memory failed we can still get to it through
PCI config space, therefore we allow ioremap() to fail.  When if fails,
however, we must leave all the IOMEM pointers as NULL.  Currently we
would calculate csr and em pointers, adding offsets to the potential
NULL value and therefore making the NULL-checks throughout the code
ineffective.

Subject: nfp: only try to get to PCIe ctrl memory if BARs are wide enough

For accessing PCIe ctrl memory we depend on the BAR aperture being
large enough to reach all registers.  Since the BAR aperture can
be set in the flash make sure the driver won't oops the kernel
when the PCIe configuration is unusual.

Subject: nfp: support long reads and writes with the cpp helpers

nfp_cpp_{read,write}() helpers perform device memory mapping (setting
the PCIe -> NOC translation BARs) and accessing it.  They, however,
currently implicitly expect that the length of entire operation will
fit in one BAR translation window.  There is a number of 16MB windows
available, and we don't really need to access such large areas today.

If the user, however, manages to trick the driver into making a big
mapping (e.g. by providing a huge fake FW file), the driver will
print a warning saying "No suitable BAR found for request" and a
stack trace - which most users find concerning.

To be future-proof and not scare users with warnings, make the
nfp_cpp_{read,write}() helpers do accesses chunk by chunk if the area
size is large.  Set the notion of "large" to 2MB, which is the size
of the smallest BAR window.

Subject: nfp: shorten CPP core probe logs

We currently print reserved BAR mappings info as we create them.
This makes the probe logs longer than necessary.  Print into a
buffer instead and log all the info as a single line.

Subject: nfp: support variable NSP response lengths

We want to support extendable commands, where newer versions
of the management FW may provide more information.  Zero out
the communication buffer before passing control to NSP.  This
way if management FW is old and only fills in first N bytes,
the remaining ones will be zeros which extended ABI fields
should reserve as not supported/not available.

Subject: nfp: don't wait for resources indefinitely

There is currently no timeout to the resource and lock acquiring
loops.  We printed warnings and depended on user sending a signal
to the waiting process to stop the waiting.  This doesn't work
very well when wait happens out of a work queue.  The simplest
example of that is PCI probe.  When user loads the module and card
is in a broken state modprobe will wait forever and signals sent
to it will not actually reach the probing thread.

Make sure all wait loops have a time out.  Set the upper wait time
to 60 seconds to stay on the safe side.

Subject: nfp: don't keep count for free buffers delayed kick

We only kick RX free buffer queue controller every NFP_NET_FL_BATCH
(currently 16) entries.  This means that we will always kick the QC
when write ring index is divisable by NFP_NET_FL_BATCH.  There is
no need to keep counts.

Subject: qed: Don't inherit RoCE DCBx for V2

Older firmware used by device didn't distinguish between RoCE and RoCE
V2 from DCBx configuration perspective, and as a result we've used to
take a the RoCE-related configuration and apply to it for both.

Since we now support configuring each its own values, there's no reason
to reflect [& configure] that both are using the same.

Subject: qed: QL41xxx VF MSI-x table

The QL41xxx adapters' PCI allows a single configuration for the
MSI-x table size of all child VFs of a given PF.
The existing code wouldn't cause the management firmware to set
that value, meaning the VFs would retain the default MSI-x table
size.

Introduce a new scheme so that whenever a VF is enabled, driver
would set the number of MSI-x to be the maximum over the various
VFs' needs.

Subject: qed: Get rid of the attention-arrays

We have almost all the necessary information regarding attentions
in the logic employed for taking register dumps.
Add some more and get rid of the seperate implementation we have today
for identifying & printing various attention sources.

Subject: qed: Diffrentiate adapter-specific attentions

There are 4 attention bits in AEU that have different meaning
for QL45xxx and QL41xxx adapters.

Instead of doing a massive infrastructure change in favor of these
bits, we implement a point fix where only those four would change
meaning dependent on the adapter involved.

Subject: qed: Print multi-bit attentions properly

In strucuture reflecting the AEU hw block some entries
represent multiple HW bits, and the associated name is in fact
a pattern.
Today, whenever such an attention would be asserted the resulted
prints would show the pattern string instead of indicating which
of the possible bits was set.

Subject: qed: Mask parities after occurance

Parities might exhibit a flood behavior since we re-enable the
attention line without preventing the parity from re-triggering the
assertion.
Mask the source in AEU until the parity would be handled.

Subject: net: phy: Add Cortina CS4340 driver

Add basic support for Cortina PHY drivers. Support only CS4340 for now.
The phys are not compatible with IEEE 802.3 clause 22/45 registers.

Implement proper read_status support. The generic 10G phy driver causes
bus register access errors.

The driver should be described using the "ethernet-phy-id" device tree
compatible.

Subject: net: qualcomm: use net_device_ops instead of direct call

There is no need to export qcaspi_netdev_open and qcaspi_netdev_close
because they are also accessible via the net_device_ops.

As preparation for the upcoming UART driver we need a module
which contains common functions for both interfaces. The module
qca_framing is a good candidate but renaming to qca_7k_common would
make it clear.

Subject: net: qualcomm: prepare frame decoding for UART driver

Unfortunately the frame format is not exactly identical between SPI
and UART. In case of SPI there is an additional HW length at the
beginning. So store the initial state to make the decoding state machine
more flexible and easy to extend for UART support.

Subject: cxgb4: FW upgrade fixes

Disable FW_OK flag while flashing Firmware. This will help to fix any
potential mailbox timeouts during Firmware flash.

Grab new devlog parameters after Firmware restart. When we FLASH new
Firmware onto an adapter, the new Firmware may have the Firmware Device Log
located at a different memory address or have a different size for it.

Subject: bnxt_en: Add a callback to inform RDMA driver during PCI shutdown.

When bnxt_en gets a PCI shutdown call, we need to have a new callback
to inform the RDMA driver to do proper shutdown and removal.

Subject: bnxt_en: Add additional chip ID definitions.

Add additional chip definitions and macros for all supported chips.
Add a new macro BNXT_CHIP_P4_PLUS for the newer generation of chips and
use the macro to properly determine the features supported by these
newer chips.

Subject: bnxt_en: Optimize doorbell write operations for newer chips.

Older chips require the doorbells to be written twice, but newer chips
do not.  Add a new common function bnxt_db_write() to write all
doorbells appropriately depending on the chip.  Eliminating the extra
doorbell on newer chips has a significant performance improvement
on pktgen.

Subject: bnxt_en: Pass in sh parameter to bnxt_set_dflt_rings().

In the existing code, the local variable sh is hardcoded to true to
calculate default rings for shared ring configuration.  It is better
to have the caller determine the value of sh.

Subject: i40e: fix race condition with PTP_TX_IN_PROGRESS bits

Hardware related to the i40e driver has a limitation on Tx PTP packets.
This requires us to limit the driver to timestamping a single packet at
once. This is done using a state bitlock which enforces that only one
timestamp request is honored at a time.

Unfortunately this suffers from a race condition. The bit lock is not
cleared until after skb_tstamp_tx() is called notifying applications of
a new Tx timestamp. Even a well behaved application sending only one
packet at a time and waiting for a response can wake up and send a new
timestamped packet request before the bit lock is cleared. This results
in needlessly dropping some Tx timestamp requests.

We can fix this by unlocking the state bit as soon as we read the
Timestamp register, as this is the first point at which it is safe to
timestamp another packet.

To avoid issues with the skb pointer, we'll use a copy of the pointer
and set the global variable in the driver structure to NULL first. This
ensures that the next timestamp request does not modify our local copy
of the skb pointer.

Now, a well behaved application which has at most one outstanding
timestamp request will not accidentally race with the driver unlock bit.
Obviously an application attempting to timestamp faster than one request
at a time will have some timestamp requests skipped. Unfortunately there
is nothing we can do about that.

Subject: i40e: avoid permanent lock of *_PTP_TX_IN_PROGRESS

The i40e driver uses a bit lock to indicate when a Tx timestamp is in
progress to avoid attempting to timestamp multiple packets at once. This
is required because hardware only has registers to handle one request at
a time.

There is a corner case where we failed to cleanup the bit lock after
a failed transmit. This can potentially result in a state bit being
locked forever.

Add some cleanup code to i40e_xmit_frame_ring to check and make sure we
cleanup incase of these failures. We also modify i40e_tx_map to return
an error code indication DMA failure.

Subject: i40e: add statistic indicating number of skipped Tx timestamps

The i40e driver can only handle one Tx timestamp request at a time.
This means it is possible for an application timestamp request to be
ignored.

There is no easy way for an administrator to determine if this occurred.
Add a new statistic which tracks this, tx_hwtstamp_skipped.

Subject: i40e: check for Tx timestamp timeouts during watchdog

The i40e driver has logic to handle only one Tx timestamp at a time,
using a state bit lock to avoid multiple requests at once.

It may be possible, if incredibly unlikely, that a Tx timestamp event is
requested but never completes. Since we use an interrupt scheme to
determine when the Tx timestamp occurred we would never clear the state
bit in this case.

Add an i40e_ptp_tx_hang() function similar to the already existing
i40e_ptp_rx_hang() function. This function runs in the watchdog routine
and makes sure we eventually recover from this case instead of
permanently disabling Tx timestamps.

Note: there is no currently known way to cause this without hacking the
driver code to force it.

Subject: ath10k: go back to using dma_alloc_coherent() for firmware scratch
 memory

This reverts commit b057886524be ("ath10k: do not use coherent memory for
allocated device memory chunks") in 2015 which converted this allocation from
dma_map_coherent() to kzalloc() / dma_map_single().

The current problem manifests when using later model NICs with larger
(>700KiB) scratch spaces in memory.  Although the kzalloc call
succeeds, the software IOMMU TLB code (via dma_map_single()) panics
because it can't find 700KiB of linear physmem bounce buffers for DMA.
Now, this is a bit of a silly failure mode for the dma map API,
but it's what we currently have to play with.

In these cases, doing kzalloc() works fine, but the dma_map_single()
call fails.

After chatting with Linus briefly about this, it indeed should be
using dma_alloc_coherent() for doing larger device memory allocation
that requires some kind of physical address mapping.

You're not supposed to be using kzalloc and dma_map_* calls for
large memory regions, and I'm guessing not for long-held mappings
either.  Typically dma mappings should be temporary for DMA,
not long held like these.

Now, since hopefully the major annoying underlying problem has also been
addressed (ie, ath10k is no longer tears down all of these allocations
and reallocates them every time the vdevs are brought down) fragmentation
should stop being such a touchy issue.  If it is though, using
dma_alloc_coherent() use gets us access to the CMB APIs too relatively
easily and ideally we would be allocating memory early in boot for
exactly these reasons.

This patch advertises TSO & GSO features in netdev->mpls_features.
In ixgbe(vf)_tso() where we set up segmentation offload, the IP
header will be the inner network header when eth_p_mpls() indicates
the Ethernet protocol is MPLS (UC or MC).

This CallTrace occurred on 32-bit kernel with CONFIG_PROVE_LOCKING
enabled.

This happens at ixgbe driver probe hardware stage, when comes to
ixgbe_get_stats64, the seqcount/seqlock still not initialize, although
this was initialize in TX/RX resources setup routin, but it was too late,
then lockdep give this Warning.

To fix this, move the u64_stats_init function to driver probe stage,
which before we get the status of seqcount and after the RX/TX ring
was finished init.

Subject: ixgbe: Remove MAC X550EM_X 1Gbase-t led_[on|off] support

Since FW configures the PHY and MAC X550EM_X has no
PHY access, led_[on|off] is not supported with the 1Gbase-t design.

Removed MAC X550EM_X 1Gbase-t led_[on|off] support by setting
function pointers to NULL and added NULL pointer checks. Also set
init_led_link_act to NULL and added NULL pointer check.

Subject: ixgbe: Correct thermal sensor event check

The thermal sensor event logic is messed up, because it can execute
the code when there is no thermal event. The current logic is that
it will exit when !capable && !event whereas it really should exit
when !capable || !event. For one thing, it means that the service
task is doing too much work. It probably has some other symptoms as
well. So, correct the logic, simplifying to only execute when there
is a thermal event. The capable check is redundant.

Subject: ixgbe: Add error checking to setting VF MAC

Currently, when setting a VF MAC address there are no error checks to
ensure that the MAC filter was successfully added.  This patch adds
additional error checks, reporting, and propagation of errors.  It also
will not set the MAC address unless adding the MAC filter was successful.

With these changes, setting the mac address to zeros can no longer call
ixgbe_set_vf_mac() as adding a zero MAC address filter is not valid.
Instead directly delete the filter and, if successful, clear the MAC
address.

The following warning is now shown as a result of new checks added for
gcc 7:

drivers/net/ethernet/intel/ixgbe/ixgbe_main.c: In function ‘ixgbe_open’:
drivers/net/ethernet/intel/ixgbe/ixgbe_main.c:3118:13: warning: ‘%d’ directive output may be truncated writing between 1 and 10 bytes into a region of size between 3 and 18 [-Wformat-truncation=]

             ^~
drivers/net/ethernet/intel/ixgbe/ixgbe_main.c:3118:6: note: directive argument in the range [0, 2147483647]

    ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      "%s-%s-%d", netdev->name, "TxRx", ri++);
      ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Resolve this warning by making a couple of changes.
 - Don't reserve space for the null terminator.  Since snprintf adds the
   null terminator automatically, there is no need for us to reserve a byte
   for it.

 - Change a couple variables that can never be negative from int to
   unsigned int.

While we're making changes to the format string, move the constant strings
into the format string instead of providing them as specifiers.

Subject: ixgbevf: Resolve truncation warning for q_vector->name
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The following warning is now shown as a result of new checks added for
gcc 7:

drivers/net/ethernet/intel/ixgbevf/ixgbevf_main.c: In function ‘ixgbevf_open’:
drivers/net/ethernet/intel/ixgbevf/ixgbevf_main.c:1363:13: warning: ‘%d’ directive output may be truncated writing between 1 and 10 bytes into a region of size between 3 and 18 [-Wformat-truncation=]
      "%s-%s-%d", netdev->name, "TxRx", ri++);
             ^~
drivers/net/ethernet/intel/ixgbevf/ixgbevf_main.c:1363:6: note: directive argument in the range [0, 2147483647]
      "%s-%s-%d", netdev->name, "TxRx", ri++);
      ^~~~~~~~~~
drivers/net/ethernet/intel/ixgbevf/ixgbevf_main.c:1362:4: note: ‘snprintf’ output between 8 and 32 bytes into a destination of size 24

    ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      "%s-%s-%d", netdev->name, "TxRx", ri++);
      ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Resolve this warning by making a couple of changes.
 - Don't reserve space for the null terminator.  Since snprintf adds the
   null terminator automatically, there is no need for us to reserve a byte
   for it.

 - Change a couple variables that can never be negative from int to
   unsigned int.

While we're making changes to the format string, move the constant strings
into the format string instead of providing them as specifiers.

Subject: ixgbe: always call setup_mac_link for multispeed fiber

Remove the logic which would previously skip the link configuration
in the case where we are already at the requested speed in
ixgbe_setup_mac_link_multispeed_fiber().

By exiting early we are skipping the link configuration and as such
the driver may not always configure the PHY correctly for SFP+.

Subject: mwifiex: usb: kill urb before free its memory

we have observed host system hang when device firmware crash,
stack trace show it was an use-after-free case: previous submitted
urb will be holding in usbcore, and given back to device driver
when device disconnected, while the urb have been freed in usb
device disconnect handler. This patch kill the holding urb before
free its memory.

Subject: mwifiex: usb: transmit aggregation packets

Instead of using 4KB packet buffer for data transfer, new chipset have
more device memory. This patch try to aggregation packets in an 16KB
buffer. In this way, totally usb transaction cost will be reduced.

Thoughput test on usb 2.0 show both TCP TX and UPD TX promote ~40M,
from ~240M to ~280M.

This feature is default disabled, and can be enabled by module
parameter, like:
insmod mwifiex.ko aggr_ctrl=1

Subject: mwifiex: usb: add timer to flush aggregation packets

Aggregation will wait for next packet until limit aggr size/number reach.
Packet might be drop and also packet dequeue will be stop in some cases.
This patch add timer to flush packets in aggregation list to avoid long
time waiting.

Subject: net: dsa: mv88e6xxx: provide a PHY setup helper

Similarly to the VTU, PVT and ATU setup, provide a mv88e6xxx_phy_setup
helper which wraps mv88e6xxx_ppu_enable, so that no more PPU-related
functions are exposed outside of phy.c.

Thus make mv88e6xxx_ppu_enable static.

Subject: net: dsa: mv88e6xxx: rename PHY PPU accessors

Make it clear that mv88e6xxx_phy_ppu_{read,write} are an implementation
of the .phy_{read,write} operations, by renaming them with the mv88e6185
prefix, since 88E6185 it is the reference switch model supported in an
upstream board (ZII Dev Rev B), which makes use of them.

Distinguish the signatures of implementation specific and generic PHY
functions in the phy.h header.

Respect the implicit naming convention used in all register sets
specific files, by renaming the mv88e6xxx_ppu_* functions with the
mv88e6xxx_phy_* prefix.

This is simply a s/xxx_ppu/xxx_phy_ppu/ substitution.

Subject: net: dsa: remove dev arg of dsa_register_switch

The current dsa_register_switch function takes a useless struct device
pointer argument, which always equals ds->dev.

Drivers either call it with ds->dev, or with the same device pointer
passed to dsa_switch_alloc, which ends up being assigned to ds->dev.

This patch removes the second argument of the dsa_register_switch and
_dsa_register_switch functions.

The new mlxfw code fails to build without the xz library:

:(.text.mlxfw_mfa2_xz_dec_run+0x8): undefined reference to `xz_dec_run'

:(.text.mlxfw_mfa2_file_component_get+0x2c0): undefined reference to `xz_dec_end'

This adds a Kconfig 'select' statement for it, which is also what
the other user of that library has.

Subject: nfp: move eBPF offload files to BPF app directory

Pure move of eBPF offload files to BPF app directory,
only change the names and relative header location.
nfp_asm.h stays in the main dir and it doesn't really
have to include nfp_bpf.h.

Date: Wed, 31 May 2017 20:19:19 +0000
Subject: dsa: add DSA switch driver for Microchip KSZ9477

The KSZ9477 is a fully integrated layer 2, managed, 7 ports GigE switch
with numerous advanced features. 5 ports incorporate 10/100/1000 Mbps PHYs.
The other 2 ports have interfaces that can be configured as SGMII, RGMII, MII
or RMII. Either of these may connect directly to a host processor or
to an external PHY. The SGMII port may interface to a fiber optic transceiver.

This driver currently supports vlan, fdb, mdb & mirror dsa switch operations.

Subject: ath10k: increase BMI timeout

When testing a 9888 chipset NIC, I notice it often takes
almost 2 seconds, and then many times OTP fails, probably due
to the two-second timeout.

[ 2269.841842] ath10k_pci 0000:05:00.0: bmi cmd took: 1984 jiffies (HZ: 1000), rv: 0
[ 2273.608185] ath10k_pci 0000:05:00.0: bmi cmd took: 1986 jiffies (HZ: 1000), rv: 0
[ 2277.294732] ath10k_pci 0000:05:00.0: bmi cmd took: 1989 jiffies (HZ: 1000), rv: 0

So, increase the BMI timeout to 3 seconds.

Subject: ath10k: initialize nbytes to 0

ath10k firmware checks nbytes == 0 as part of determining if DMA
has completed successfully.  To help make this work more often,
have the driver initialize nbytes to zero when freeing the descriptor
slot.

Subject: ath10k: add BMI parameters to fix calibration from DT/pre-cal

QCA99X0, QCA9888, QCA9984 supports calibration data in
either OTP or DT/pre-cal file. Current ath10k supports
Calibration data from OTP only.

If caldata is loaded from DT/pre-cal file, fetching board id
and applying calibration parameters like tx power gets failed.

error log:
[   15.733663] ath10k_pci 0000:01:00.0: failed to fetch board file: -2
[   15.741474] ath10k_pci 0000:01:00.0: could not probe fw (-2)

This patch adds calibration data support from DT/pre-cal
file.  Below parameters are used to get board id and
applying calibration parameters from cal data.

		EEPROM[OTP]	FLASH[DT/pre-cal file]
Cal param	0x700		0x10000
Board id	0x10		0x8000

Tested on QCA9888 with pre-cal file.

Subject: ath10k: fix the logic of limiting tdls peer counts

The original idea is to limit the maximum TDLS peer link, but the logic
is always false, and never be able to restrict the number of TDLS peer
creation.

Fix the logic here and also move the checking earlier, so that it could
avoid to handle the failure case, e.g disable the tdls peer, delete the
peer and also vdev count cleanup.

Since the commit 55454a565836 ("ppp: avoid dealock on recursive xmit"),
the PPP xmit path is protected by wrapper functions which disable the
bh already. So it is unnecessary to disable the bh again in the real
xmit path.

Subject: qed: IGU read revised

As a first step for relaxing various assumptions done by driver
about the IGU mapping, the driver is now going to read the entire
IGU into a shadow copy, and mark in its database each status block
that's relevant for it.

Subject: qed: Distinguish between sb_id and igu_sb_id

In qed code, sb_id means 2 different things:
  - An interrupt vector [usually when received as a parameter from
    a protocol driver, but not only] that's associated with a status
    block.

  - An index to a status block entity existing in HW.

This patch renames the references to the HW entity, adding an 'igu_'
prefix to allow an easier distinction.

Subject: qed: Add aux. function translating sb_id -> igu_sb_id

An additional step for relaxing the IGU order assumption, we now add
an auxiliary function that can be used for finding the HW status block
that's associated with a given MSI-x vector.

Subject: qed: Remove assumption on SB order in IGU

Current code assumes there's a known layout for SBs in the IGU,
where all the SBs of a single entity would be laid in consecutive
order of vectors.

While the assumption is still kept by management firmware, we already
have the necessary information to eliminate it, so no reason to keep
it in code.

Subject: qed: Provide auxiliary for getting free VF SB

IOV code is very intrusive in its manipulation of the status block
database.
Add a new auxiliary function to allow the PF to find an available unused
status block to configure for a specific VF's MSI-x vector.

Subject: qed: Hold a single array for SBs

A PF today holds 2 different arrays - one holding information
about the HW configuration and one holding information about
the SBs that are used by the protocol drivers.
These arrays aren't really connected - e.g., protocol driver
initializing a given SB would not mark the same SB as occupied
in the HW shadow array.

Move into a single array [at least for PFs] - hold the mapping
of the driver-protocol SBs on the HW entry which they configure.

Subject: qed: Reset IGU CAM to default on init

The IGU CAM contains an assocaition between hardware SBs
and interrupt lines, and it can be dynamically configured
to allow more interrupts in one entity over another, specifically
for Re-distibution of SBs between a PF and its child VFs.

While we don't yet use this functionality, there are other
clients that do and as such its possible the information
passed from management firmware during initialization in
regard to the possible number of SBs doesn't accurately reflect
the current HW configuration.

The following changes are going to apply to the driver init sequence:

 a. PF is going to re-configure all entries belonging to itself and
    its child VFs in IGU CAM based on the management firmware info
    regarding the number of SBs that are supposed to exist there.

 b. PF is going to stop using the SB resource [management firmware
    provided information] for anything but the initialization.
    Instead, it would use the live-time counters it maintains for
    the numbers.

Subject: qed: No need to reset SBs on IOV init

Since we're resetting the IGU CAM each time we initialize the PF
device, there's no need to reset the VF SBs again when initializing
IOV.

Subject: mlxsw: spectrum: Implement the ethtool flash_device callback

Add callback to the ethtool flash_device op. This callback uses the mlxfw
module to flash the new firmware file to the device.

As the firmware flash process takes about 20 seconds and ethtool takes the
rtnl lock during the flash_device callback, release the rtnl lock at the
beginning of the flash process and take it again before leaving the
callback. This way, the rtnl is not held during the process. To make sure
the device does not get deleted during the flash process, take a reference
to it before releasing the rtnl lock.

drivers/net/ethernet/mellanox/mlxsw/spectrum_router.c:3310: undefined reference to `br_vlan_enabled'

Add Kconfig dependency to enforce usable configurations.

Subject: i40evf: drop i40e_type.h include

This drops the i40e_type.h include in anticipation of the next
patch which moves this file to a location where type.h doesn't
exist, and all the places this file is included already include
i40e_type.h before this file.

Subject: i40e/i40evf: create and use new unified header file

This moves a header for i40evf to include/linux/avf/virtchnl.h.
The directory name AVF is an acronym for the Intel(R) Adaptive
Virtual Function.

This first step creates the new file, which is a rename of
drivers/net/ethernet/intel/i40evf/i40e_virtchnl.h to
include/linux/avf/virtchnl.h, and should show up in git
as a rename when using git log --follow.

To keep things building after the move, the changes to the i40evf
driver are made to point to the new include file location.

-/* Description:
- * This header file describes the VF-PF communication protocol used
- * by the various i40e drivers.
- *
- * Admin queue buffer usage:
- * desc->opcode is always i40e_aqc_opc_send_msg_to_pf
- * flags, retval, datalen, and data addr are all used normally.
- * Firmware copies the cookie fields when sending messages between the PF and
- * VF, but uses all other fields internally. Due to this limitation, we
- * must send all messages as "indirect", i.e. using an external buffer.
- *
- * All the vsi indexes are relative to the VF. Each VF can have maximum of
- * three VSIs. All the queue indexes are relative to the VSI.  Each VF can
- * have a maximum of sixteen queues for all of its VSIs.
- *
- * The PF is required to return a status code in v_retval for all messages
- * except RESET_VF, which does not require any response. The return value is of
- * i40e_status_code type, defined in the i40e_type.h.
- *
- * In general, VF driver initialization should roughly follow the order of these
- * opcodes. The VF driver must first validate the API version of the PF driver,
- * then request a reset, then get resources, then configure queues and
- * interrupts. After these operations are complete, the VF driver may start
- * its queues, optionally add MAC and VLAN filters, and process traffic.

From: Jesse Brandeburg <jesse.brandeburg@intel.com>
Date: Thu, 11 May 2017 11:23:10 -0700
Subject: i40e: use new unified virtchnl header file

This patch changes the i40e driver to start using the new virtchnl
interface header file, and removes an already existing duplicate of the
i40e_virtchnl.h file contained in the i40e directory.

-/* Description:
- * This header file describes the VF-PF communication protocol used
- * by the various i40e drivers.
- *
- * Admin queue buffer usage:
- * desc->opcode is always i40e_aqc_opc_send_msg_to_pf
- * flags, retval, datalen, and data addr are all used normally.
- * Firmware copies the cookie fields when sending messages between the PF and
- * VF, but uses all other fields internally. Due to this limitation, we
- * must send all messages as "indirect", i.e. using an external buffer.
- *
- * All the vsi indexes are relative to the VF. Each VF can have maximum of
- * three VSIs. All the queue indexes are relative to the VSI.  Each VF can
- * have a maximum of sixteen queues for all of its VSIs.
- *
- * The PF is required to return a status code in v_retval for all messages
- * except RESET_VF, which does not require any response. The return value is of
- * i40e_status_code type, defined in the i40e_type.h.
- *
- * In general, VF driver initialization should roughly follow the order of these
- * opcodes. The VF driver must first validate the API version of the PF driver,
- * then request a reset, then get resources, then configure queues and
- * interrupts. After these operations are complete, the VF driver may start
- * its queues, optionally add MAC and VLAN filters, and process traffic.

Subject: virtchnl: rename i40e to generic virtchnl

This morphs all the i40e and i40evf references to/in virtchnl.h
to be generic, using only automated methods. Updates all the
callers to use the new names.  A followup patch provides separate
clean ups for messy line conversions from these "automatic"
changes, to make them more reviewable.

Subject: virtchnl: move some code to core driver

Before moving this function over to virtchnl.h, move
some driver specific checks that had snuck into a fairly
generic function, back into the caller of the function.

Subject: i40e/virtchnl: refactor code for validate checks

This change updates the arguments passed to the validate function
and fixes the caller, as well as uses the new return values added to
virtchnl.h

One other minor tweak, remove a duplicate set to zero of valid_len.

This is in preparation for moving the function to virtchnl.h.

Subject: virtchnl: finish conversion to virtchnl interface

This patch implements the complete version of the virtchnl.h file
with final renames, and fixes the related code in i40e and i40evf.

It also expands comments, and adds details on the usage of
certain fields.

In addition, due to the changes a couple of casts are needed
to prevent errors found by sparse after renaming some fields.

Subject: i40e/virtchnl: move function to virtchnl

This moves a function that is needed for the virtchnl interface
from the i40e PF driver over to the virtchnl.h file.

It was manually verified that the function in question is unchanged
except for the function name and function header, which explains
the slight difference in the number of lines removed/added.

Subject: iwlwifi: mvm: document which group enums are used with which group ID

Make it explicit which command definition enum is supposed to be
used with which command group, rather than relying on being able
to figure it out by name.

Subject: iwlwifi: mvm: use proper sta_addr in firmware API

There's no point to declare an address as a __le32/__le16
and then only take a pointer to it anyway, change that to
just a sta_addr[ETH_ALEN].

Subject: iwlwifi: mvm: document structures used by commands

Add documentation to a lot of command IDs that links to the
appropriate structure(s) used with those IDs. In one case,
actually add and use a new struct for that purpose.

Subject: iwlwifi: Add fw_name_pre_rf_next_step to support different rf steps

Integrated chip may have different HW and RF steps.
Currently, the driver supports only different HW steps.
Add logic to support different RF steps enables combining different
HW and RF steps.

Subject: iwlwifi: mvm: remove unused REPLY_MAX

This value is unused, and there's no reason we'd ever use it.
Just remove it.

Subject: iwlwifi: add wait for tx queue empty

Now that we have 512 queues, add a wait for single TX
queue to gen2.
This replaces gen1 wait_tx_queues_empty, which was limited
to 32 queues.

Subject: qed: Correct order of wwnn and wwpn

Driver reads values via HSI splitting this 8-byte into 2 32-bit
values and builds a single u64 field - but it does so by shifting
the lower field instead of the higher.
Luckily, we still don't use these fields for anything - but we're about
to start.

Share several new tidbits with qedf:
 - wwpn & wwnn
 - Absolute pf-id [this one is actually meant for qedi as well]
 - Number of available CQs

While we're at it, now that qedf will be aware of the available CQs
we can add some validation on the inputs it provides.

Subject: liquidio: VF interrupt initialization cleanup

Set initialization state variable to (reflect interrupt initialization) at
correct time (immediately after having configured interrupts).  This fixes
problem of inconsistent IRQ allocation in case of [obscure] failure when
negotiating with PF driver during init.

Clean-up of interrupt enablement during initialization & avoid potential
race condition with chip-specific code (i.e. perform interrupt control in
main driver module).  Added explanatory comments regarding interrupt
enablement.

Subject: mdio: mux: make child bus walking more permissive and errors more
 verbose

If any errors are encountered while walking the device tree structure of
the MDIO bus for children, the code may silently continue, silently
exit, or throw an error and exit.  This make it difficult for device
tree writers to know there is an error.  Also, it makes any error in a
child entry of the MDIO bus be fatal for all entries.  Instead, we
should provide verbose errors describing the error and then attempt to
continue if it all possible.  Also, use of_mdio_parse_addr()

functions m88e1510_get_temp_critical, m88e1510_set_temp_critical and
m88e1510_get_temp_alarm can be made static as they not need to be
in global scope.

Cleans up sparse warnings:
 "symbol 'm88e1510_get_temp_alarm' was not declared. Should it be static?"
 "symbol 'm88e1510_get_temp_critical' was not declared. Should it be

The mv88e6xxx.h is meant to contains the chip structures and data.
Rename it to chip.h, as for other source/header pairs of the driver.

At the same time, ensure that relative header inclusions are separated

Subject: qed: Add bitmaps for VF CIDs

Each PF has a bitmap for its own ranges of CIDs, to allow easy grabbing
of an available CID when such is needed. But VFs are not using the same
mechanism, instead relying on hard-coded CIDs [ queue-index == cid ].

As an infrastructure step toward increasing number of CIDs of VFs,
the PF is going to maintain bitmaps for the VF CIDs as well -
the bitmaps would be per-VF and the ranges would be the same [in HW all
VFs of a given PF have the same mapping of CIDs, and the HW is capable
of distinguishing between those according to the VF index]

Subject: qed: Create L2 queue database

First step in allowing a single PF/VF to open multiple queues on
the same queue zone is to add per-hwfn database of queue-cids
as a two-dimensional array where entry would be according to
[queue zone][internal index].

Part of an effort of a cleaner seperation between qed and the protocol
drivers, the L2 interface is to use the SB structure for initialization
purposes opaquely.

Subject: qed: Pass vf_params when creating a queue-cid

We're going to need additional information for queue-cids
that a PF creates for its VFs, so start by refactoring existing
logic used for initializing said struct into receiving a structure
encapsulating the VF-specific information that needs to be provided.

This also introduces QED_QUEUE_CID_SELF - each queue-cid would hold
an indication to whether it belongs to the hw-function holding it
[whether that's a PF or a VF], or else what's the VF id it belongs
to.

Subject: qed: Assign a unique per-queue index to queue-cid

When a queue-cid is allocated, assign an index inside that's
CID's queue-zone.

For PFs and VFS, this number is going to be unique and derive
from a per-queue-zone bitmap, while for PF's VFs queues the
number is currently going to constant; Later, we'd add the
capability of a VF to communicate such an index to its PF.

Subject: qed: Make VF legacy a bitfield

Until now we used to have a single VF legacy compatibility mode,
one that affected the place of the Rx producers of those VFs [mostly].

As PF would soon support allocating CIDs for VFs instead of having
a static CID<->queue configuration for them, we'll need to have
an additional legacy mode since existing VFs would need to continue
on using the older mode of operation.

Change the infrastrucutre so that the legacy would be able to indicate
which of the legacy behaviors is needed for a given VF.

From 08bc8f15e69cbd9f8e3d7bbba4814cec50d51cfe Mon Sep 17 00:00:00 2001
From: "Mintz, Yuval" <Yuval.Mintz@cavium.com>

Subject: qed: Multiple qzone queues for VFs

This adds the infrastructure for supporting VFs that want to open
multiple transmission queues on the same queue-zone.
At this point, there are no VFs that actually request this functionality,
but later patches would remedy that.

 a. VF and PF would communicate the capability during ACQUIRE;
    Legacy VFs would continue on behaving as they do today

 b. PF would communicate number of supported CIDs to the VF
    and would enforce said limitation

 c. Whenever VF passes a request for a given queue configuration
    it would also pass an associated index within said queue-zone

Subject: qed: VFs to try utilizing the doorbell bar

VFs are currently not mapping their doorbell bar, instead relying
on the small doorbell window they have in their limited regview bar.

In order to increase the number of possible Tx connections [queues]
employeed by VF past 16, we need to start using the doorbell bar if
one such is exposed - VF would communicate this fact to PF which would
return the size-bar internally configured into chip, according to
which the VF would decide whether to actually utilize the doorbell
bar.

Subject: qed: VF XDP support

The final addition on the qed front -
 - VFs would now require their PFs to provide multiple CIDs
 - Based on the availability of connections from PF, determine whether
   XDP is feasible and share it with qede via dev_info.

Subject: qede: VF XDP support

This introduces 2 changes needed for XDP to be supported for VFs:

 a. On VF-side, publish the NDO based on qed outputs

 b. On PF-side, request qed to allocate sufficient cids per-VF
    to allow the child vfs to support it

Subject: net-next: stmmac: dwmac-sun8i: ensure the EPHY is properly reseted

The EPHY may be already enabled by bootloaders which have Ethernet
capability (e.g. current U-Boot). Thus it should be reseted properly
before doing the enabling sequence in the dwmac-sun8i driver, otherwise
the EMAC reset process may fail if no cable is plugged, and then fail
the dwmac-sun8i probing.

Tested on Orange Pi PC, One and Zero. All the boards fail to have
dwmac-sun8i probed with "EMAC reset timeout" without cable plugged
before, and with this fix they're now all able to successfully probe the
EMAC without cable plugged and then use the connection after a cable is
hot-plugged in.

From 7042678dffa3707dea3feb34f09241d54e40648c Mon Sep 17 00:00:00 2001

Subject: iwlwifi: cleanup references to 8000 family in NVM code

NVM code is tightly coupled with 8000 family, while
it really refers to extended NVM format introduced
back then. Separate it to a configuration dependent
boolean, and rename defines accordingly.

Subject: iwlwifi: remove references to 8000 B-step devices

We don't have any 8000 B-step right now, and there is no
firmware loading code for them anyway.
Further more, 9000 B-step devices will hit those code paths.
Remove code that was introduced only for 8000 B-step.

Subject: iwlwifi: mvm: support init flow debugging

In case an assert happens on init flow, the current
driver powers down the NIC, except if iwlmvm modparam
init_dbg=1, and only on very specific flows.

Extend this capability to cover most failure cases
by keeping track of what init configurations have been
completed. This way, we can allow NOT powering down
the NIC, while making sure that when the driver is
removed we don't try to free resources that haven't
been allocated. (This can result in a kernel panic.)

Subject: iwlwifi: pcie: support dumping FH in a000 hw

FH in A000 HW are placed in a different location,
and need to be read as prph, rather than direct.
Support A000 dumping as well as legacy.

Subject: iwlwifi: mvm: disable prph collection in a000 hw

Apart from the current list of PRPH that can't be
collected in A000 HW, the rest of the debug dump
data the driver collects is valid, so there is no
need to disable collection only because of this.

Disable PRPH collecting in A000 HW, and allow
collecting the rest of the debug data.

Subject: iwlwifi: mvm: check firmware is up in debugfs

Protect various debugfs files that need to communicate with the
firmware from being used when the firmware isn't running.

Some will just reject getting written to, while others that store
some state will simply store it and not apply it immediately.

Subject: iwlwifi: mvm: convert ucode_loaded to a status bit

Convert ucode_loaded to a status bit called FIRMWARE_RUNNING.
This will make it easier to clear this earlier, to avoid any
spurious accesses while shutting down, for example through
debugfs.

Subject: iwlwifi: mvm: clear firmware running bit earlier

Clear the firmware running bit before flushing the FW (error) dump
work, because otherwise debugfs isn't blocked (previous patch) and
can cause a new work to be scheduled, which will then run after we
actually shut down the device, wreaking havoc. Clearing it ensures
that debugfs can't interfere anymore, and we can safely cancel or
flush the work struct.

Subject: iwlwifi: remove unnecessary code in iwl_trans_alloc_tx_cmd

When we removed dev_cmd_headroom, the check for dev_cmd_ptr == NULL
became unnecessary, since we just return dev_cmd_ptr anyway.  Cleanup
the function to avoid useless code.

Subject: mdio: mux: fix an incorrect less than zero error check using a u32

The u32 variable v is being checked to see if an error return is
less than zero and this check has no effect because it is unsigned.
Fix this by making v and int (this also matches the type of
cb->bus_number which is assigned to the value in v).

Detected by CoverityScan, CID#1440454 ("Unsigned compared against zero")

Subject: igb: Explicitly select page 0 at initialization

The functions igb_read_phy_reg_gs40g/igb_write_phy_reg_gs40g (which were
removed in 2a3cdea) explicitly selected the required page at every phy_reg
access. Currently, igb_get_phy_id_82575 relays on the fact that page 0 is
already selected. The assumption is not fulfilled for my Lex 3I380CW
motherboard with integrated dual i211 based gigabit ethernet. This leads to igb
initialization failure and network interfaces are not working:

    igb: Intel(R) Gigabit Ethernet Network Driver - version 5.4.0-k
    igb: Copyright (c) 2007-2014 Intel Corporation.
    igb: probe of 0000:01:00.0 failed with error -2
    igb: probe of 0000:02:00.0 failed with error -2

In order to fix it, we explicitly select page 0 before first access to phy
registers.

The new wake function is only used by the suspend/resume handlers that

warning:

Subject: e1000e: fix race condition around skb_tstamp_tx()

The e1000e driver and related hardware has a limitation on Tx PTP
packets which requires we limit to timestamping a single packet at once.
We do this by verifying that we never request a new Tx timestamp while
we still have a tx_hwtstamp_skb pointer.

Unfortunately the driver suffers from a race condition around this. The
tx_hwtstamp_skb pointer is not set to NULL until after skb_tstamp_tx()
is called. This function notifies the stack and applications of a new
timestamp. Even a well behaved application that only sends a new request
when the first one is finished might be woken up and possibly send
a packet before we can free the timestamp in the driver again. The
result is that we needlessly ignore some Tx timestamp requests in this
corner case.

Fix this by assigning the tx_hwtstamp_skb pointer prior to calling
skb_tstamp_tx() and use a temporary pointer to hold the timestamped skb
until that function finishes. This ensures that the application is not
woken up until the driver is ready to begin timestamping a new packet.

This ensures that well behaved applications do not accidentally race
with condition to skip Tx timestamps. Obviously an application which
sends multiple Tx timestamp requests at once will still only timestamp
one packet at a time. Unfortunately there is nothing we can do about
this.

Subject: igb: fix race condition with PTP_TX_IN_PROGRESS bits

Hardware related to the igb driver has a limitation of only handling one
Tx timestamp at a time. Thus, the driver uses a state bit lock to
enforce that only one timestamp request is honored at a time.

Unfortunately this suffers from a simple race condition. The bit lock is
not cleared until after skb_tstamp_tx() is called notifying the stack of
a new Tx timestamp. Even a well behaved application which sends only one
timestamp request at once and waits for a response might wake up and
send a new packet before the bit lock is cleared. This results in
needlessly dropping some Tx timestamp requests.

We can fix this by unlocking the state bit as soon as we read the
Timestamp register, as this is the first point at which it is safe to
unlock.

To avoid issues with the skb pointer, we'll use a copy of the pointer
and set the global variable in the driver structure to NULL first. This
ensures that the next timestamp request does not modify our local copy
of the skb pointer.

This ensures that well behaved applications do not accidentally race
with the unlock bit. Obviously an application which sends multiple Tx
timestamp requests at once will still only timestamp one packet at
a time. Unfortunately there is nothing we can do about this.

Subject: igb: avoid permanent lock of *_PTP_TX_IN_PROGRESS

The igb driver uses a state bit lock to avoid handling more than one Tx
timestamp request at once. This is required because hardware is limited
to a single set of registers for Tx timestamps.

The state bit lock is not properly cleaned up during
igb_xmit_frame_ring() if the transmit fails such as due to DMA or TSO
failure. In some hardware this results in blocking timestamps until the
service task times out. In other hardware this results in a permanent
lock of the timestamp bit because we never receive an interrupt
indicating the timestamp occurred, since indeed the packet was never
transmitted.

Fix this by checking for DMA and TSO errors in igb_xmit_frame_ring() and
properly cleaning up after ourselves when these occur.

The e1000e driver can only handle one Tx timestamp request at a time.
This means it is possible for an application timestamp request to be
ignored.

There is no easy way for an administrator to determine if this occurred.
Add a new statistic which tracks this, tx_hwtstamp_skipped.

Subject: igb: add statistic indicating number of skipped Tx timestamps

The igb driver can only handle one Tx timestamp request at a time.
This means it is possible for an application timestamp request to be
ignored.

There is no easy way for an administrator to determine if this occurred.
Add a new statistic which tracks this, tx_hwtstamp_skipped.

Subject: igb: check for Tx timestamp timeouts during watchdog

The igb driver has logic to handle only one Tx timestamp at a time,
using a state bit lock to avoid multiple requests at once.

It may be possible, if incredibly unlikely, that a Tx timestamp event is
requested but never completes. Since we use an interrupt scheme to
determine when the Tx timestamp occurred we would never clear the state
bit in this case.

Add an igb_ptp_tx_hang() function similar to the already existing
igb_ptp_rx_hang() function. This function runs in the watchdog routine
and makes sure we eventually recover from this case instead of
permanently disabling Tx timestamps.

Note: there is no currently known way to cause this without hacking the
driver code to force it.

Subject: e1000e: Don't return uninitialized stats

Some statistics passed to ethtool are garbage because e1000e_get_stats64()
doesn't write them, for example: tx_heartbeat_errors. This leaks kernel
memory to userspace and confuses users.

Do like ixgbe and use dev_get_stats() which first zeroes out
rtnl_link_stats64.

Subject: s390/qeth: remove skb_is_nonlinear() check on IQD

qeth doesn't advertise NETIF_F_SG for L3 IQDs. So trust the stack to
not hand us any nonlinear skbs, and remove an always-true condition.

With the fact that data_offset < 0 is no longer possible on IQDs,
apply a small cleanup to subsequent code.

Subject: s390/qeth: add support for early L3 device setup

Similar to how qeth currently does early L2 setup of OSM and OSN
devices, add support for early setup of L3-only devices.
This adds a qeth_l3_devtype that contains all core and l3-specific
sysfs attributes, so that they can be created in one go while probing.

This just adds the infrastructure, exploitation of the support happens
in a subsequent patch.

Subject: s390/qeth: do early device setup for z/VM IQD NICs

qeth currently supports early setup for OSM and OSN devices.
This patch adds early setup support for z/VM HiperSockets,
since they can only be coupled to L3 networks.

Based on an initial version by Dmitriy Lakhvich.

Subject: net: dsa: mv88e6xxx: fix 6085 frame mode masking

The register bits used for the frame mode were masked with DSA (0x1)
instead of the mask value (0x3) in the 6085 implementation of
port_set_frame_mode. Fix this.

Subject: tun: use symmetric hash

Tun actually expects a symmetric hash for queue selecting to work
correctly, otherwise packets belongs to a single flow may be
redirected to the wrong queue. So this patch switch to use
__skb_get_hash_symmetric().

Subject: net: phy: avoid genphy_aneg_done() for PHYs without clause 22 support

Avoid calling genphy_aneg_done() for PHYs that do not implement the
Clause 22 register set.

Clause 45 PHYs may implement the Clause 22 register set along with the
Clause 22 extension MMD.  Hence, we can't simply block access to the
Clause 22 functions based on the PHY being a Clause 45 PHY.

Subject: net: phy: hook up clause 45 autonegotiation restart

genphy_restart_aneg() can only restart autonegotiation on clause 22
PHYs.  Add a phy_restart_aneg() function which selects between the
clause 22 and clause 45 restart functionality depending on the PHY
type and whether the Clause 45 PHY supports the Clause 22 register set.

Subject: net: phy: add Marvell Alaska X 88X3310 10Gigabit PHY support

Add phylib support for the Marvell Alaska X 10 Gigabit PHY (MV88X3310).
This phy is able to operate at 10G, 1G, 100M and 10M speeds, and only
supports Clause 45 accesses.

The PHY appears (based on the vendor IDs) to be two different vendors
IP, with each devad containing several instances.

This PHY driver has only been tested with the RJ45 copper port, fiber
port and a Marvell Armada 8040-based ethernet interface.

It should be noted that to use the full range of speeds, MAC drivers
need to also reconfigure the link mode as per phydev->interface, since
the PHY automatically changes its interface mode depending on the
negotiated speed.

Subject: net: fec: Clear and enable MIB counters on imx51

Both the IMX51 and IMX53 datasheet indicates that the MIB counters
should be cleared during setup. Otherwise random numbers are returned
via ethtool -S.  Add a quirk and a function to do this.

Tested on an IMX51.

Subject: nfp: reorder open and close functions

We will soon reuse parts of .ndo_stop() for clean up after errors
in .ndo_open().  Reorder the associated functions to make that possible.

No functional changes.

Subject: nfp: split out the allocation part of open

Our open/close implementations have 3 stages:
 - allocation/freeing of ring resources, irqs etc.,
 - device config,
 - device/stack enable (can't fail).

Right now all of those stages are placed in separate functions,
apart from allocation during open.  Fix that.  It will make it
easier for us to allocate resources for netdev-less vNICs.
Because we want to reuse allocation code in netdev-less vNICs
leave the netif_set_real_num_[rt]x_queues() calls inside open.

Subject: nfp: make sure debug accesses don't depend on netdevs

We want to be able to inspect the state of descriptor rings of
the control vNIC, so it will use the same interface as data vNICs.

Make sure the code doesn't use netdevs to determine state
of the rings and names things appropriately.

Subject: nfp: add control vNIC datapath

Since control vNICs don't have a netdev, they can't use napi and
queuing stack provides.  Add simple tasklet-based data receive
and send of control messages with queuing on a skb_list.

Subject: nfp: make vNIC ctrl memory mapping function reusable

We will soon need to map control vNIC PCI memory as well as data vNIC
memory.  Make the function for mapping areas pointed to by an RTsym
reusable.

Subject: nfp: map all queue controllers at once

RX and TX queue controllers are interleaved.  Instead of creating
two mappings which map the same area at slightly different offset,
create only one mapping.  Always map all queue controllers to simplify
the code and allow reusing the mapping for non-data vNICs.

Subject: nfp: don't clutter init code passing fw_ver around

Reading fw version from the BAR is trivial.  Don't pass it around
through layers of init functions, simply read it again where needed.

This commit has the side effect of each vNIC having the exact NFD
version from its own control memory, rather than all data vNICs
assuming the version of the first one.  This should not result in
user-visible changes, though.  Capabilities of data vNICs of trival
apps are identical.

Subject: nfp: slice the netdev spawning function

We want to be able to create a special vNIC for control messages.
This vNIC should be created before any netdev is registered to allow
nfp_app logic to exchange messages with the FW app before any netdev
is visible to user space.  Unfortunately we can't enable IRQs until
we know how many vNICs we will need to spawn.

Divide the function which spawns netdevs for vNICs into three parts:
 - vNIC/memory allocation;
 - IRQ allocation;
 - netdev init and register.

This will help us insert the initialization of the control channel
after IRQ allocation but before netdev init and register.

Subject: nfp: advertise support for NFD ABI 0.5

NFD ABI 0.5 is equivalent to NFD ABI 3.0 but requires that the
driver checks the APP id symbol and makes sure it can support
given app.  Most advanced apps will likely require control vNIC
(ability to exchange control messages between the driver and
app FW).  Detailed app version checking and capability exchange
is left to app-specific code.

Subject: cxgb4: Fix tids count for ipv6 offload connection

the adapter consumes two tids for every ipv6 offload
connection be it active or passive, calculate tid usage
count accordingly.

Also change the signatures of relevant functions to get
the address family.

Subject: vxlan: use a more suitable function when assigning NULL

When stopping the vxlan interface we detach it from the socket.
Use RCU_INIT_POINTER() and not rcu_assign_pointer() to do so.

The unwind failures stems from commit 2800209994f8 ("e1000e: Refactor PM
flows"), but it may be a later patch that introduced the non-recoverable
behaviour.

Remove the limitation that offloaded NIC filters can have only one
action. This allows us for example to provide flow tag as a note
to upper layers / apps that that HW header re-write was applied.

Subject: net/mlx5e: Use short attribute form when adding/deleting offloaded TC
 flows

Instead of going through flow->nic/esw_attr for each usage, assign
an attr pointer per the context (nic or esw) and use that.

This patch doesn't add any functionality.

Subject: net/mlx5e: Add cache for HW modify header IDs

Packets belonging to flows which are different by matching may still need
to go through the same header re-write. Add a cache for header re-write IDs
keyed by the binary chain of modify header actions.

The caching is supported for both eswitch and NIC use-cases, where the
actual conversion of the code to use caching comes in next patches, one
per use-case.

Subject: net/mlx5e: Support header re-write of partial fields in TC pedit
 offload

Using a per field mask field, the TC pedit action supports modifying
partial fields. E.g if using the TC tool, the following example would
make the kernel to only re-write two bytes of the src ip address:

tc filter add dev enp1s0 protocol ip parent ffff: prio 30
	flower skip_sw ip_proto udp dst_port 8001
	action pedit ex munge ip src set 10.1.0.0 retain 0xffff0000

We add driver support for offload these partial re-writes, by setting
the per FW action offset-in-field and length-from-offset attributes.

The 1st bit set in the mask specifies both the offset and the right
shift to apply on the value such that the 1st bit which needs to be
set will reside in bit 0 of the FW data field.

Subject: net: propagate tc filter chain index down the ndo_setup_tc call

We need to push the chain index down to the drivers, so they have the
information to which chain the rule belongs. For now, no driver supports
multichain offload, so only chain 0 is supported. This is needed to
prevent chain squashes during offload for now. Later this will be used
to implement multichain offload.

Subject: tcp: add a struct net parameter to tcp_parse_options()

We want to move some TCP sysctls to net namespaces in the future.

tcp_window_scaling, tcp_sack and tcp_timestamps being fetched
from tcp_parse_options(), we need to pass an extra parameter.

Now that the DSA core adds the CPU and DSA ports itself to the new VLAN
entry, there is no need to include them as members of this VLAN when
initializing a new VTU entry.

As of now, initialize a new VTU entry with all ports excluded.

Subject: net: dsa: mv88e6xxx: do not skip ports on VLAN del

The mv88e6xxx driver currently tries to be smart and remove by itself a
VLAN entry from the VTU when the driven switch sees no user ports as
members of the VLAN.

This is bad in a multi-chip switch fabric, since a chip in between
others may have no bridge port members, but still needs to be aware of
the VID in order to correctly pass frames in the data path.

Now that the DSA core explicitly manages DSA and CPU ports, do not skip
them when checking remaining VLAN members.

Subject: net: bridge: Add support for notifying devices about FDB add/del

Currently the bridge doesn't notify the underlying devices about new
FDBs learned. The FDB sync is placed on the switchdev notifier chain
because devices may potentially learn FDB that are not directly related
to their ports, for example:

1. Mixed SW/HW bridge - FDBs that point to the ASICs external devices
                        should be offloaded as CPU traps in order to
			perform forwarding in slow path.
2. EVPN - Externally learned FDBs for the vtep device.

Notification is sent only about static FDB add/del. This is done due
to fact that currently this is the only scenario supported by switch
drivers.

Subject: mlxsw: spectrum_switchdev: Change switchdev notifier API

The current API for sending switchdev notifications implies only FDB
add/del. In order to support notification about successful FDB offload
the API is changed.

Subject: mlxsw: spectrum_switchdev: Add support for learning FDB through
 notification

Add support for learning FDB through notification. The driver defers
the hardware update via ordered work queue. Support for stacked devices
is also provided. In case of a successful FDB add a notification is
sent back to bridge.

The FDB add/del are now done through the notification chain. The FDBs
are synced with the bridge and there is no need for extra dumping.

Subject: net: Remove support for bridge bypass ndos from stacked devices

Remove support for bridge bypass ndos from stacked devices. At this point
no driver which supports stack device behavior offload supports operation
with SELF flag. The case for upper device is already taken care of in both
of the following cases:

1. FDB add/del - driver should check at the notification cb if the
                 stacked device contains his ports.

2. Port attribute - calls switchdev code directly which checks
                    for case of stack device.

Subject: rocker: Remove support for bridge FDB learning sync

Currently the rocker driver supports an option for disabling syncing
the hardware learned FDBs with the software bridge. This behavior
breaks the bridge offload model and thus it is removed.

Currently the switchdev_trans struct is embedded in the world_ops API.
In order to add support for adding FDB via a notfication chain the API should

Subject: rocker: Remove support for bypass bridge port attributes/vlan set

The bridge port attributes/vlan for mlxsw devices should be set only
from bridge code. The vlans are synced totally with the bridge so
there is no need to special dump support.

Subject: mlxsw: spectrum: Simplify port split flow

In commit be94535f9531 ("mlxsw: spectrum: Make split flow match firmware
requirements") we had to modify the port split flow to overcome quirks
in the device's firmware. This resulted in asymmetrical code with
regards to port creation and removal.

The problem in the firmware is long gone and since we can now enforce a
minimal firmware version, we can simplify the code and make it symmetric
again.

Subject: mlxsw: spectrum: Pass port argument to module mapping functions

Previous patch made it unnecessary to map ports to modules before we
allocate their struct. We can now therefore pass the port struct to
these functions, thereby making them consistent with other functions
that operate on ports.

Add compatible values for WiLink chips from 128x and 180x series.
Also the DT binding already contained compatible values for the 127x
series, but the driver did not. This brings the list on par with
the list from wlcore (the wifi driver).

Subject: Bluetooth: hci_ll: Add support for the external clock

Add support to manage the external clock provided to the WiLink combo chip
as it's needed for any of the transport interfaces.

To avoid breaking platforms not yet specifying the external clock, we make
it optional. In case the clock is successfully fetched during ->probe(),
let's manage it via the ->open|close() callbacks, to make sure the device
get properly powered on/off.

Fixes: ea452678734e ("arm64: dts: hikey: Fix WiFi support")

Subject: net: dsa: mv888e6xxx: do not use netdev printing

The mv888e6xxx driver accesses a port's netdev mostly for printing.

This is bad for 2 reasons: DSA and CPU ports do not have a netdev
pointer; it doesn't give us a correct picture of why a DSA driver might
need to access a port's netdev.

Instead simply use dev_* printing functions with chip->dev (or ds->dev
depending on the scope, both guaranteed to exist), with a p%d prefix for
the target port.

Subject: net: dsa: mv88e6xxx: do not prefix ops with g1

The mv88e6xxx_ops describe functionalities, regardless their locations
(which can be Global1, Global2, or whatever register set.)

Rename the g1_set_cpu_port and g1_set_egress_port ops to set_cpu_port
and set_egress_port. No functional changes.

Subject: net: dsa: mv88e6xxx: rework pause limit operation

All Marvell chips supporting Pause frames limiting use 1-byte value for
input and output.

Old chips have both bytes adjacent in a 16-bit register. New ones have
an indirect table using 8-bit data.

The mv88e6xxx library functions (such as in port.c) must not contain
driver logic, but only generic helpers. This patch changes the
port_pause_config operation for port_pause_limit taking two u8 arguments
for input and output limits. There is no functional changes.

Subject: net: dsa: mv88e6xxx: rework jumbo size operation

Marvell chips have a Jumbo Mode to set the maximum frame size (MTU).

The mv88e6xxx_ops structure is meant to contain generic functionalities,
no driver logic. Change port_jumbo_config to port_set_jumbo_size setting
the mode from a given maximum size value.

There is no functional changes since we still use 10240 bytes.

At the same time, correctly clear all Jumbo Mode bits before writing.

Subject: Ipvlan should return an error when an address is already in use.

The ipvlan code already knows how to detect when a duplicate address is
about to be assigned to an ipvlan device.  However, that failure is not
propogated outward and leads to a silent failure.

Introduce a validation step at ip address creation time and allow device
drivers to register to validate the incoming ip addresses.  The ipvlan
code is the first consumer.  If it detects an address in use, we can
return an error to the user before beginning to commit the new ifa in
the networking code.

This can be especially useful if it is necessary to provision many
ipvlans in containers.  The provisioning software (or operator) can use
this to detect situations where an ip address is unexpectedly in use.

Subject: Bluetooth: hci_intel: Add GPIO ACPI mapping table

In order to make GPIO ACPI library stricter prepare users of
gpiod_get_index() to correctly behave when there no mapping is
provided by firmware.

Here we add explicit mapping between _CRS GpioIo() resources and
their names used in the driver.

Subject: nfp: make sure to cancel port refresh on the error path

If very last stages of netdev registering and init fail some
other netdevs and devlink ports may have been visible to user
space before we torn them back down.  In this case there is a
slight chance user may have triggered port refresh.  We need
to make sure the async work is cancelled.

We have to cancel after releasing pf->lock, so we will always
try to cancel, regardless of which part of probe has failed.

Subject: nfp: remove automatic caching of RTsym table

The fact that RTsym table is cached inside nfp_cpp handle is
a relic of old times when nfpcore was a library module.  All
the nfp_cpp "caches" are awkward to deal with because of
concurrency and prone to keeping stale information.  Make
the run time symbol table be an object read out from the device
and managed by whoever requested it.  Since the driver loads
FW at ->probe() and never reloads, we can hold onto the table
for ever.

Subject: cxgb4: handle interrupt raised when FW crashes

Handle TIMER0INT when FW crashes. Check for PCIE_FW[FW_EVAL]
and if it says "Device FW Crashed", then treat it as fatal.
Else, non-fatal.

Use another way to keep disabling the U2P3 for both RTL_VER_03 and
RTL_VER_04.

Move enabling U2P3 from r8153_init() to r8153_hw_phy_cfg(). The
engineer ask the setting should be done after PHY settings.

Disable U2P3 first in rtl8153_up().

Subject: qed: Cleaner seperation of LL2 inputs

A LL2 connection [qed_ll2_info] has a sub-structure of type qed_ll2_conn
that contain various inputs for ll2 acquisition, but the connection also
utilizes a couple of other inputs.

Restructure the input structure to include all the inputs and refactor
the code necessary to populate those.

Subject: qed*: LL2 callback operations

LL2 today is interrupt driven - when tx/rx completion arrives [or any
other indication], qed needs to operate on the connection and pass
the information to the protocol-driver [or internal qed consumer].
Since we have several flavors of ll2 employeed by the driver,
each handler needs to do an if-else to determine the right functionality
to use based on the connection type.

In order to make things more scalable [given that we're going to add
additional types of ll2 flavors] move the infrastrucutre into using
a callback-based approach - the callbacks would be provided as part
of the connection's initialization parameters.

Subject: qed: add qed_int_sb_init() stub function

When CONFIG_QED_SRIOV is disabled, we get a build error:

drivers/net/ethernet/qlogic/qed/qed_int.c: In function 'qed_int_sb_init':
drivers/net/ethernet/qlogic/qed/qed_int.c:1499:4: error: implicit declaration of function 'qed_vf_set_sb_info'; did you mean 'qed_mcp_get_resc_info'? [-Werror=implicit-function-declaration]

All the other declarations have a 'static inline' stub as an alternative
here, so this adds one more for qed_int_sb_init.

Subject: bonding: warn user when 802.3ad speed is unknown

Goal is to advertise the user when ethtool speeds and 802.3ad speeds are
desynchronized.
When this case happens, the kernel needs to be patched.

Subject: net: fec: Add a fec_enet_clear_ethtool_stats() stub for CONFIG_M5272

Commit 2b30842b23b9 ("net: fec: Clear and enable MIB counters on imx51")
introduced fec_enet_clear_ethtool_stats(), but missed to add a stub
for the CONFIG_M5272=y case, causing build failure for the
m5272c3_defconfig.

Add the missing empty stub to fix the build failure.

Subject: net: ethernet: ti: cpsw: enable HWTSTAMP_FILTER_PTP_V1_L4_EVENT
 filter

CPSW driver supports PTP v1 messages, but for unknown reasons this filter
is not advertised. As result,
./tools/testing/selftests/networking/timestamping/timestamping utility
can't be used for testing of CPSW RX timestamping with option
SOF_TIMESTAMPING_RX_HARDWARE, because it uses
HWTSTAMP_FILTER_PTP_V1_L4_SYNC filter.

Hence, fix it by advertising HWTSTAMP_FILTER_PTP_V1_L4_XXX filters
in CPSW driver.

The hardware supports the MTU to be changed and the driver it self is
somewhat prepared to support this. This patch hooks up the callbacks to
be able to change the MTU from user-space.

Subject: brcmfmac: add support multi-scheduled scan

This change adds support for multi-scheduled scan in the driver. It
currently relies on g-scan support in firmware and will set struct
wiphy::max_sched_scan_reqs accordingly. This is limited to 16 concurrent
requests.

The firmware currently has a limit of 64 channels that can be configured
for all requests in total regardless whether there are duplicates. So if
a request uses 35 channels there are 29 channels left for another request.
When user-space does not specify any channels cfg80211 will add all
channels defined by the wiphy instance to the request, which makes
reaching the limit rather easy for dual-band devices.

Subject: brcmfmac: add mutex to protect pno requests

The request references kept in pno are accessed in user-space context
and in firmware event handler context. As such we need to protect it
with a lock. As both context allow sleep a mutex seems appropriate.

Subject: brcmfmac: add scheduled scan support for specified BSSIDs

Add support to handle scheduled scan request containing BSSID in
the matchsets. The firmware can send event upon finding BSSIDs and
SSIDs. To get these in one event the bit REPORT_SEPARATELY needed
to be removed from the flags in brcmf_pno_config().

Subject: brcmfmac: Fix glom_skb leak in brcmf_sdiod_recv_chain

An earlier change to this function (3bdae810721b) fixed a leak in the
case of an unsuccessful call to brcmf_sdiod_buffrw(). However, the
glom_skb buffer, used for emulating a scattering read, is never used
or referenced after its contents are copied into the destination
buffers, and therefore always needs to be freed by the end of the
function.

Fixes: 3bdae810721b ("brcmfmac: Fix glob_skb leak in brcmf_sdiod_recv_chain")
Fixes: a413e39a38573 ("brcmfmac: fix brcmf_sdcard_recv_chain() for host without sg support")

Subject: qtnfmac: check band before allocating cmd_skb to avoid resource leak

The current code allocates cmd_skb and then will leak this if band->band
is an illegal value. It is simpler to sanity check the band first before
allocating cmd_skb so that we don't have to free cmd_skb if an invalid
band occurs.

Detected by CoverityScan, CID#1437561 ("Resource Leak")

From: Yan-Hsuan Chuang <yhchuang@realtek.com>
Date: Mon, 5 Jun 2017 10:29:53 -0500
Subject: rtlwifi: btcoex: settings before firmware is downloaded

The btcoex is sometimes unstable because there are some unexpected
behaviors before the firmware has been downloaded successfully.

Therefore we force the antenna path settings to avoid this, then let the
firmware control the btcoexistence when the firmware is ready.

Subject: rtlwifi: btcoex: add settings before the hardware is ready

When the hardware is turned on and in the initialization stage, the PTA
circuit is unstable. Hence we need to force some hardware settings to
make sure the PTA circuit work correctly, otherwise it may affect the
user's experience.

Subject: rtlwifi: btcoex: let btcoex get wifi rssi and link status

Instead of rssi status, the btcoex also needs to get the link status of
the wifi. In addition, some of the rssi status can be merged into link
status.

Subject: mwifiex: Replace semaphore async_sem with mutex

The semaphore 'async_sem' is used as a simple mutex, so
it should be written as one. Semaphores are going away in the future.

Subject: wlcore: add wl1285 compatible

Motorola Droid 4 uses a WL 1285C. With differences between
chips not being public let's add explicit binding for wl1285
instead of relying on wl1283 being very similar.

Subject: net: dsa: mv88e6xxx: prefix Port Status macros

For implicit namespacing and clarity, prefix the common Port Status
Register macros with MV88E6XXX_PORT_STS and the ones which differ
between implementations with a chosen reference model
(e.g. MV88E6352_PORT_STS_EEE.)

Document the register and prefer ordered hex masks values for all
Marvell 16-bit registers.

Subject: net: dsa: mv88e6xxx: prefix Port MAC Control macros

For implicit namespacing and clarity, prefix the common MAC Control
Register macros with MV88E6XXX_PORT_MAC_CTL and the ones which differ
between implementations with a chosen reference model
(e.g. MV88E6065_PORT_MAC_CTL_SPEED_200.)

Document the register and prefer ordered hex masks values for all
Marvell 16-bit registers.

Subject: net: dsa: mv88e6xxx: prefix Port Jamming macros

For implicit namespacing and clarity, prefix the common Port Jamming
Control Register macros with MV88E6XXX_PORT_JAM_CTL and the ones which
differ between implementations with a chosen reference model
(e.g. MV88E6097_PORT_JAM_CTL.)

The 88E6390 family renamed the register to Flow Control and turned it
into an indirect table. Document that as well.

Document the register and prefer ordered hex masks values for all
Marvell 16-bit registers.

Subject: net: dsa: mv88e6xxx: prefix Port Switch ID macros

For implicit namespacing and clarity, prefix the common Switch ID
Register macros with MV88E6XXX_PORT_SWITCH_ID.

Document the register and prefer ordered hex masks values for all
Marvell 16-bit registers, this means shifting their values by 4.

Subject: net: dsa: mv88e6xxx: prefix Port Control macros

For implicit namespacing and clarity, prefix the common Port Control
Register macros with MV88E6XXX_PORT_CTL0 and the ones which differ
between implementations with a chosen reference model
(e.g. MV88E6185_PORT_CTL0_USE_TAG.)

The reason for CTL0 is to make it clear between the badly named
"Port Control", "Port Control 1" and "Port Control 2" registers.

Document the register and prefer ordered hex masks values for all
Marvell 16-bit registers.

Subject: net: dsa: mv88e6xxx: prefix Port Control 2 macros

For implicit namespacing and clarity, prefix the common Port Control 2
Register macros with MV88E6XXX_PORT_CTL2 and the ones which differ
between implementations with a chosen reference model
(e.g. MV88E6095_PORT_CTL2_CPU_PORT_MASK.)

Document the register and prefer ordered hex masks values for all
Marvell 16-bit registers.

Subject: net: dsa: mv88e6xxx: prefix Port Egress Rate Control macros

For implicit namespacing and clarity, prefix the common Port Egress Rate
Control and Port Egress Rate Control 2 registers macros with
MV88E6XXX_PORT_EGRESS_RATE_CTL1 and MV88E6XXX_PORT_EGRESS_RATE_CTL2.

Document the register and prefer ordered hex masks values for all
Marvell 16-bit registers.

Subject: net: mvpp2: enable basic 10G support

On GOP port 0 two MAC modes are available: GMAC and XLG. The XLG MAC is
used for 10G connectivity. This patch adds a basic 10G support by
allowing to use the XLG MAC on port 0 and by reworking the
port_enable/disable functions so that the XLG MAC is configured when
using 10G.

Subject: ibmvnic: Client-initiated failover

The IBM vNIC protocol provides support for the user to initiate
a failover from the client LPAR in case the current backing infrastructure
is deemed inadequate or in an error state.

Support for two H_VIOCTL sub-commands for vNIC devices are required
to implement this function. These commands are H_GET_SESSION_TOKEN
and H_SESSION_ERR_DETECTED.

"[H_GET_SESSION_TOKEN] is used to obtain a session token from a VNIC client
adapter.  This token is opaque to the caller and is intended to be used in
tandem with the SESSION_ERROR_DETECTED vioctl subfunction."

"[H_SESSION_ERR_DETECTED] is used to report that the currently active
backing device for a VNIC client adapter is behaving poorly, and that
the hypervisor should attempt to fail over to a different backing device,
if one is available."

To provide tools access to this functionality the vNIC driver creates a
sysfs file that, when written to, will send a request to pHyp to failover
to a different backing device.

Subject: ibmvnic: Remove netdev notify for failover resets

When handling a driver reset due to a failover of the backing
server on the vios, doing the netdev_notify_peers() can cause
network traffic to stall or halt. Remove the netdev notify call
for failover resets.

Commit 4c5e7a2c0501 ("dt-bindings: mdio: Clarify binding document")
declared that a MDIO reset GPIO property should have only a single GPIO
reference/specifier, however the supporting code was left intact, still
burdening the kernel with now apparently useless loops -- get rid of them.

The MDIO reset GPIO is really a classical optional GPIO property case,
so devm_gpiod_get_optional() should have been used, not devm_gpiod_get().
Doing this  saves several LoCs...

Subject: of_mdio: move of_mdio_parse_addr to header file

The of_mdio_parse_addr() helper function is useful to other code, but
the module dependency chain causes issues.  To work around this, we can
move of_mdio_parse_addr() to be an inline function in the header file.
This gets rid of the dependencies and still allows for the reuse of
code.

Subject: net: dsa: Remove master_netdev and use dst->cpu_dp->netdev

In preparation for supporting multiple CPU ports, remove
dst->master_netdev and ds->master_netdev and replace them with only one
instance of the common object we have for a port: struct
dsa_port::netdev. ds->master_netdev is currently write only and would be
helpful in the case where we have two switches, both with CPU ports, and
also connected within each other, which the multi-CPU port patch series
would address.

While at it, introduce a helper function used in net/dsa/slave.c to
immediately get a reference on the master network device called
dsa_master_netdev().

Subject: ixgbe: fix race condition with PTP_TX_IN_PROGRESS bits

Hardware related to the ixgbe driver is limited to handling a single Tx
timestamp request at a time. Thus, the driver ignores requests for Tx
timestamp while waiting for the current request to finish. It uses
a state bit lock which enforces that only one timestamp request is
honored at a time.

Unfortunately this suffers from a simple race condition. The bit lock is
not cleared until after skb_tstamp_tx() is called notifying applications
of a new Tx timestamp. Even a well behaved application sending only one
packet at a time and waiting for a response can wake up and send a new
packet before the bit lock is cleared. This results in needlessly
dropping some Tx timestamp requests.

We can fix this by unlocking the state bit as soon as we read the
Timestamp register, as this is the first point at which it is safe to
unlock.

To avoid issues with the skb pointer, we'll use a copy of the pointer
and set the global variable in the driver structure to NULL first. This
ensures that the next timestamp request does not modify our local copy
of the skb pointer.

This ensures that well behaved applications do not accidentally race
with the unlock bit. Obviously an application which sends multiple Tx
timestamp requests at once will still only timestamp one packet at
a time. Unfortunately there is nothing we can do about this.

Subject: ixgbe: avoid permanent lock of *_PTP_TX_IN_PROGRESS

The ixgbe driver uses a state bit lock to avoid handling more than one Tx
timestamp request at once. This is required because hardware is limited
to a single set of registers for Tx timestamps.

The state bit lock is not properly cleaned up during
ixgbe_xmit_frame_ring() if the transmit fails such as due to DMA or TSO
failure. In some hardware this results in blocking timestamps until the
service task times out. In other hardware this results in a permanent
lock of the timestamp bit because we never receive an interrupt
indicating the timestamp occurred, since indeed the packet was never
transmitted.

Fix this by checking for DMA and TSO errors in ixgbe_xmit_frame_ring() and
properly cleaning up after ourselves when these occur.

Subject: ixgbe: add statistic indicating number of skipped Tx timestamps

The ixgbe driver can only handle one Tx timestamp request at a time.
This means it is possible for an application timestamp request to be
ignored.

There is no easy way for an administrator to determine if this occurred.
Add a new statistic which tracks this, tx_hwtstamp_skipped.

Subject: ixgbe: check for Tx timestamp timeouts during watchdog

The ixgbe driver has logic to handle only one Tx timestamp at a time,
using a state bit lock to avoid multiple requests at once.

It may be possible, if incredibly unlikely, that a Tx timestamp event is
requested but never completes. Since we use an interrupt scheme to
determine when the Tx timestamp occurred we would never clear the state
bit in this case.

Add an ixgbe_ptp_tx_hang() function similar to the already existing
ixgbe_ptp_rx_hang() function. This function runs in the watchdog routine
and makes sure we eventually recover from this case instead of
permanently disabling Tx timestamps.

Note: there is no currently known way to cause this without hacking the
driver code to force it.

Subject: ixgbe: pci_set_drvdata must be called before register_netdev

We call pci_set_drvdata immediately after calling register_netdev,
which leaves a window where tasks writing to the sriov_numvfs sysfs
attribute can sneak in and crash the kernel.  register_netdev cleans
up after itself so placing pci_set_drvdata immediately before it
should preserve the intent of commit 0fb6a55cc31f ("ixgbe: fix crash
on rmmod after probe fail").

Subject: net/mlxfw: fix a NULL dereference

If we hit this error path we end up returning ERR_PTR(0) which is NULL.
The caller is not expecting that so it results in a NULL dereference.

Fixes: 410ed13cae39 ("Add the mlxfw module for Mellanox firmware flash process")

Subject: net: dsa: mv88e6xxx: prefix Global Switch MAC macros

Prefix and document the Global Switch MAC Address Register macros and
give clear 16-bit register representation.

At the same time, move mv88e6xxx_g1_set_switch_mac in global1.c, where
it belongs.

Subject: net: dsa: mv88e6xxx: prefix Global Monitor Control macros

Prefix and document the Global Monitor Control Register macros
(which became the Global Monitor & MGMT Control Register with 88E6390)
and give a clear 16-bit registers representation.

Use __bf_shf to get the shift value at compile time instead of adding
new defined macros for it.

Subject: sunvnet: restrict advertized checksum offloads to just IP

As much as we'd like to play well with others, we really aren't
handling the checksums on non-IP protocol packets very well.  This
is easily seen when trying to do TCP over ipv6 - the checksums are
garbage.

Here we restrict the checksum feature flag to just IP traffic so
that we aren't given work we can't yet do.

RX buffer pools are disabled while awaiting a device
reset if firmware indicates that the resource is closed.

This patch fixes a bug where pools were not being
subsequently enabled after the device reset, causing
the device to become inoperable.

Subject: ibmvnic: Remove VNIC_CLOSING check from pending_scrq

Fix a kernel panic resulting from data access of a NULL
pointer during device close. The pending_scrq routine is
meant to determine whether there is a valid sub-CRQ message
awaiting processing. When the device is closing, however,
there is a possibility that NULL messages can be processed
because pending_scrq will always return 1 even if there
no valid message in the queue.

It's not clear what this closing state check was originally
meant to accomplish, so just remove it.

Subject: r8152: add byte_enable for ocp_read_word function

Add byte_enable for ocp_read_word() to replace reading 4
bytes data with reading the desired 2 bytes data.

This is used to avoid the issue which is described in
commit b4d99def0938 ("r8152: remove sram_read"). The
original method always reads 4 bytes data, and it may
have problem when reading the PHY registers.

The new method is supported since RTL8153B, but it
doesn't influence the previous chips. The bits of the
byte_enable for the previous chips are the reserved
bits, and the hw would ignore them.

Subject: net/mlx5: Fix some spelling mistakes

Fixed few places where endianness was misspelled and
one spot whwere output was:

CHECK: 'endianess' may be misspelled - perhaps 'endianness'?
CHECK: 'ouput' may be misspelled - perhaps 'output'?

Subject: net/mlx5: Undo LAG upon request to create virtual functions

LAG cannot work if virtual functions are present. Therefore, if LAG is
configured, the attempt to create virtual functions will fail. This gives
precedence to LAG over SRIOV which is not the desired behavior as users
might want to use the bonding/teaming driver also want to work with SRIOV.
In that case we don't want to force an order of actions, first create
virtual functions and only than configure a bonding/teaming net device.
To fix, if LAG is configured during a request to create virtual
functions, remove it and continue.

We ignore ENODEV when trying to forbid lag. This makes sense
because "No such device" means that lag is forbidden anyway.

Rename rx_symbol_errors_phy to rx_pcs_symbol_err_phy, in order to
prevent confusion with rx_symbol_err_phy counter.

rx_pcs_symbol_err_phy counter counts the number of symbol errors that
were detected on the PCS (regardless of traffic) and weren't
corrected by FEC correction algorithm or that FEC algorithm was
not active on this interface.

rx_symbol_err_phy refers to errors on packet level (physical error
during a packet receive).

Also allocate the output buffer on the stack instead of the heap, to reduce
number of heap allocs on update_stats work.

Subject: net/mlx5e: Optimize update stats work

Unlike ethtool stats, get_stats ndo provides information cached by
update stats work that is running in the background without updating
them explicitly.
We cannot update all counters inside the ndo because some
updates require firmware commands that cannot be performed under a
spinlock.

update_stats work does not need to update ALL counters, since only
some of them are needed by ndo_get_stats.
This patch will allow for a minimal run of update_stats using an extra
parameter which will update necessary counters only and cut 13
firmware commands in each iteration of the work.

Work duration previous to this patch: ~4200us.
Work duration after this patch: ~700us (17% of the original time).

Subject: net/mlx5: Expose command polling interface

Add a new interface for commands execution that allows the
caller to wait for the command's completion in a busy-wait
loop (polling mode).

This is useful if we want to execute a command in a polling mode
while the driver is working in events mode for the rest of
the commands.
This interface will be used in the downstream patches.

Subject: net/mlx5: Add fast unload support in shutdown flow

Adding a support to flush all HW resources with one FW command and
skip all the heavy unload flows of the driver on kernel shutdown.
There's no need to free all the SW context since a new fresh kernel
will be loaded afterwards.

Regarding the FW resources, they should be closed, otherwise we will
have leakage in the FW. To accelerate this flow, we execute one command
in the beginning that tells the FW that the driver isn't going to close
any of the FW resources and asks the FW to clean up everything.
Once the commands complete, it's safe to close the PCI resources and
finish the routine.

Subject: atm: solos-pci: remove useless variable assignments

Value assigned to variable _data32_ at lines 1254 and 1257 is
overwritten at line 1260 before it can be used. This makes
such variable assignments useless.

Subject: net/mlx4_en: Remove unused argument in TX datapath function

Remove owner argument, as it is obsolete and unused.
This also saves the overhead of calculating its value in data-path.

Subject: net/mlx4_en: Optimized single ring steering

Avoid touching RX QP RSS context when loading with only
one RX ring, to allow optimized A0 RX steering.

Enable by:
- loading mlx4_core with module param: log_num_mgm_entry_size = -6.
- then: ethtool -L <interface> rx 1

Performance tests:
Tested on ConnectX3Pro, Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz

Subject: net/mlx4_en: Improve receive data-path

Several small performance improvements in RX datapath,
including:
- Compiler branch predictor hints.
- Replace a multiplication with a shift operation.
- Minimize variables scope.
- Write-prefetch for packet header.
- Avoid trinary-operator ("?") when value can be preset in a matching
  branch.
- Save a branch by updating RX ring doorbell within
  mlx4_en_refill_rx_buffers(), which now returns void.

Performance tests:
Tested on ConnectX3Pro, Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz
Single queue no-RSS optimization ON
(enable by ethtool -L <interface> rx 1).

XDP_DROP packet rate:
Same (28.1 Mpps), lower CPU utilization (from ~100% to ~92%).

Drop packets in TC:
-------------------------------------
     | Before    | After     | Gain |
IPv4 | 4.14 Mpps | 4.18 Mpps |   1% |
-------------------------------------

XDP_TX packet rate:
-------------------------------------
     | Before    | After     | Gain |
IPv4 | 10.1 Mpps | 10.3 Mpps |   2% |
IPv6 | 10.1 Mpps | 10.3 Mpps |   2% |

Subject: net/mlx4_en: Improve transmit CQ polling

Several small performance improvements in TX CQ polling,
including:
- Compiler branch predictor hints.
- Minimize variables scope.
- More proper check of cq type.
- Use boolean instead of int for a binary indication.

Performance tests:
Tested on ConnectX3Pro, Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz

Packet-rate tests for both regular stack and XDP use cases:
No noticeable gain, no degradation.

Subject: net/mlx4_en: Improve stack xmit function

Several small code and performance improvements in stack TX datapath,
including:
- Compiler branch predictor hints.
- Minimize variables scope.
- Move tx_info non-inline flow handling to a separate function.
- Calculate data_offset in compile time rather than in runtime
  (for !lso_header_size branch).
- Avoid trinary-operator ("?") when value can be preset in a matching
  branch.

Performance tests:
Tested on ConnectX3Pro, Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz

Gain is too small to be measurable, no degradation sensed.
Results are similar for IPv4 and IPv6.

Subject: net/mlx4_en: Improve XDP xmit function

Several performance improvements in XDP TX datapath,
including:
- Ring a single doorbell for XDP TX ring per NAPI budget,
  instead of doing it per a lower threshold (was 8).
  This includes removing the flow of immediate doorbell ringing
  in case of a full TX ring.
- Compiler branch predictor hints.
- Calculate values in compile time rather than in runtime.

Performance tests:
Tested on ConnectX3Pro, Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz
Single queue no-RSS optimization ON.

XDP_TX packet rate:
-------------------------------------
     | Before    | After     | Gain |
IPv4 | 10.3 Mpps | 12.0 Mpps |  17% |
IPv6 | 10.3 Mpps | 12.0 Mpps |  17% |

Subject: net/mlx4_en: Poll XDP TX completion queue in RX NAPI

Instead of having their own NAPIs, XDP TX completion queues get
polled within the corresponding RX NAPI.
This prevents any possible race on TX ring prod/cons indices,
between the context that issues the transmits (RX NAPI) and the
context that handles the completions (was previously done in
a separate NAPI).

This also improves performance, as it decreases the number
of NAPIs running on a CPU, saving the overhead of syncing
and switching between the contexts.

Performance tests:
Tested on ConnectX3Pro, Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz
Single queue no-RSS optimization ON.

XDP_TX packet rate:
-------------------------------------
     | Before    | After     | Gain |
IPv4 | 12.0 Mpps | 13.8 Mpps |  15% |
IPv6 | 12.0 Mpps | 13.8 Mpps |  15% |

Subject: net/mlx4_en: Increase default TX ring size

Increase the default TX ring size (from 512 to 1024) to match
the RX ring size.
This gives the XDP TX ring a better chance to keep up with the
rate of its RX ring in case of a high load of XDP_TX actions.

Tested:
Ethtool counter rx_xdp_tx_full used to increase, after applying this
patch it stopped.

Subject: net/mlx4_en: Replace TXBB_SIZE multiplications with shift operations

Define LOG_TXBB_SIZE, log of TXBB_SIZE, and use it with a shift
operation instead of a multiplication with TXBB_SIZE.
Operations are equivalent as TXBB_SIZE is a power of two.

Performance tests:
Tested on ConnectX3Pro, Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz

Gain is too small to be measurable, no degradation sensed.
Results are similar for IPv4 and IPv6.

From 4c07c132408a685d31bb6e638aef4d245e30703a Mon Sep 17 00:00:00 2001
From: Tariq Toukan <tariqt@mellanox.com>
Date: Thu, 15 Jun 2017 14:35:40 +0300
Subject: net/mlx4_en: Refactor mlx4_en_free_tx_desc

Some code re-ordering, functionally equivalent.

- The !tx_info->inl check is evaluated anyway in both flows
  (common case/end case). Run it first, this might finish
  the flows earlier.
- dma_unmap calls are identical in both flows, get it out
  of the if block into the common area.

Performance tests:
Tested on ConnectX3Pro, Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz

Gain is too small to be measurable, no degradation sensed.
Results are similar for IPv4 and IPv6.

Subject: ath10k: define structures for CE ctrl/misc register

Define structures for the copy engine ctrl/misc registers,
that includes CE CMD halt, watermark source, watermark destination,
host IE ring, source, destination and dmax ring.

This adds support to avoid the conditional compilation,
code optimization and dynamic configuration of the copy engine
register map for respective hardware bus interface.

Subject: r8152: move calling delay_autosuspend function

Move calling delay_autosuspend() in rtl8152_runtime_suspend(). Calling
delay_autosuspend() as late as possible.

The original flows are
   1. check if the driver/device is busy now.
   2. set wake events.
   3. enter runtime suspend.

If the wake event occurs between (1) and (2), the device may miss it. Besides,
to avoid the runtime resume occurs after runtime suspend immediately, move the
checking to the end of rtl8152_runtime_suspend().

Subject: networking: introduce and use skb_put_data()

A common pattern with skb_put() is to just want to memcpy()
some data into the new space, introduce skb_put_data() for
this.

An spatch similar to the one for skb_put_zero() converts many
of the places using it:

Subject: networking: make skb_put & friends return void pointers

It seems like a historic accident that these return unsigned char *,
and in many places that means casts are required, more often than not.

Make these functions (skb_put, __skb_put and pskb_put) return void *
and remove all the casts across the tree, adding a (u8 *) cast only
where the unsigned char pointer was used directly, all done with the
following spatch:

    @@
    expression SKB, LEN;
    typedef u8;
    identifier fn = { skb_put, __skb_put };
    @@
    - *(fn(SKB, LEN))
    + *(u8 *)fn(SKB, LEN)

    @@
    expression E, SKB, LEN;
    identifier fn = { skb_put, __skb_put };
    type T;
    @@
    - E = ((T *)(fn(SKB, LEN)))
    + E = fn(SKB, LEN)

which actually doesn't cover pskb_put since there are only three
users overall.

A handful of stragglers were converted manually, notably a macro in
drivers/isdn/i4l/isdn_bsdcomp.c and, oddly enough, one of the many
instances in net/bluetooth/hci_sock.c. In the former file, I also
had to fix one whitespace problem spatch introduced.

Subject: networking: make skb_pull & friends return void pointers

It seems like a historic accident that these return unsigned char *,
and in many places that means casts are required, more often than not.

Make these functions return void * and remove all the casts across
the tree, adding a (u8 *) cast only where the unsigned char pointer
was used directly, all done with the following spatch:

From 634fef61076d644b989b86abc2f560d81a089a31 Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Fri, 16 Jun 2017 14:29:24 +0200
Subject: networking: add and use skb_put_u8()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Joe and Bjørn suggested that it'd be nicer to not have the
cast in the fairly common case of doing
	*(u8 *)skb_put(skb, 1) = c;

Add skb_put_u8() for this case, and use it across the code,
using the following spatch:

    @@
    expression SKB, C, S;
    typedef u8;
    identifier fn = {skb_put};
    fresh identifier fn2 = fn ## "_u8";
    @@
    - *(u8 *)fn(SKB, S) = C;
    + fn2(SKB, C);

Note that due to the "S", the spatch isn't perfect, it should
have checked that S is 1, but there's also places that use a
sizeof expression like sizeof(var) or sizeof(u8) etc. Turns
out that nobody ever did something like
	*(u8 *)skb_put(skb, 2) = c;

which would be wrong anyway since the second byte wouldn't be
initialized.

Subject: net: mvmdio: put the poll intervals in the ops structure

Put the two poll intervals (min and max) in the driver's ops
structure. This is needed to add the xmdio support later.

Subject: net: mvmdio: check the MII_ADDR_C45 bit is not set for smi operations

Add a check for the read and write smi operations, to ensure the
MII_ADDR_C45 bit isn't set. This will be needed as soon as the xSMI
support is added to the mvmdio driver.

Subject: net: mvmdio: add xmdio xsmi support

This patch adds the xmdio xsmi interface support in the mvmdio driver.
This interface is used in Ethernet controllers on Marvell 370, 7k and 8k
(as of now). The xsmi interface supported by this driver complies with
the IEEE 802.3 clause 45. The xSMI interface is used by 10GbE devices.

Subject: net: dsa: loop: Implement ethtool statistics

When a DSA driver implements ethtool statistics, we also override the
master network device's ethtool statistics with the CPU port's
statistics and this has proven to be a possible source of bugs in the
past. Enhance the dsa_loop.c driver to provide statistics under the
forme of ok/error reads and writes from the per-port PHY read/writes.

Subject: ibmvnic: driver initialization for kdump/kexec

When booting into the kdump/kexec kernel, pHyp and vios
are not prepared for the initialization crq request and
a failover transport event is generated. This is not
handled correctly.

At this point in initialization the driver is still in
the 'probing' state and cannot handle a full reset of the
driver as is normally done for a failover transport event.

To correct this we catch driver resets while still in the
'probing' state and return EAGAIN. This results in the
driver tearing down the main crq and calling ibmvnic_init()
again.

Subject: ipv6: take dst->__refcnt for insertion into fib6 tree

In IPv6 routing code, struct rt6_info is created for each static route
and RTF_CACHE route and inserted into fib6 tree. In both cases, dst
ref count is not taken.
As explained in the previous patch, this leads to the need of the dst
garbage collector.

This patch holds ref count of dst before inserting the route into fib6
tree and properly releases the dst when deleting it from the fib6 tree
as a preparation in order to fully get rid of dst gc later.

Also, correct fib6_age() logic to check dst->__refcnt to be 1 to indicate
no user is referencing the dst.

And remove dst_hold() in vrf_rt6_create() as ip6_dst_alloc() already puts
dst->__refcnt to 1.

Subject: net: remove DST_NOCACHE flag

DST_NOCACHE flag check has been removed from dst_release() and
dst_hold_safe() in a previous patch because all the dst are now ref
counted properly and can be released based on refcnt only.
Looking at the rest of the DST_NOCACHE use, all of them can now be
removed or replaced with other checks.
So this patch gets rid of all the DST_NOCACHE usage and remove this flag
completely.

Subject: NFC: nfcmrvl: do not use device-managed resources

This specifically fixes resource leaks in the registration error paths.

Device-managed resources is a bad fit for this driver as devices can be
registered from the n_nci line discipline. Firstly, a tty may not even
have a corresponding device (should it be part of a Unix98 pty)
something which would lead to a NULL-pointer dereference when
registering resources.

Secondly, if the tty has a class device, its lifetime exceeds that of
the line discipline, which means that resources would leak every time
the line discipline is closed (or if registration fails).

Currently, the devres interface was only being used to request a reset
gpio despite the fact that it was already explicitly freed in
nfcmrvl_nci_unregister_dev() (along with the private data), something
which also prevented the resource leak at close.

Note that the driver treats gpio number 0 as invalid despite it being
perfectly valid. This will be addressed in a follow-up patch.

This specifically fixes a NULL-pointer dereference in
nfcmrvl_fw_dnld_init() during registration when the underlying tty is
one end of a Unix98 pty.

Note that the driver still uses the phy device for any debugging, which
is fine for now.

Subject: NFC: nfcmrvl: fix firmware-management initialisation

The nci-device was never deregistered in the event that
fw-initialisation failed.

Fix this by moving the firmware initialisation before device
registration since the firmware work queue should be available before
registering.

Note that this depends on a recent fix that moved device-name
initialisation back to to nci_allocate_device() as the
firmware-workqueue name is now derived from the nfc-device name.

Subject: NFC: nfcmrvl_usb: use interface as phy device

Use the USB-interface rather than parent USB-device device, which is
what this driver binds to, when registering the nci device.

Note that using the right device is important when dealing with device-
managed resources as the interface can be unbound independently of the
parent device.

Also note that private device pointer had already been set by
nfcmrvl_nci_register_dev() so the redundant assignment can therefore be
removed.

Subject: pptp: Remove unused variable in pptp_release()

Variable opt in pptp_release() is set but never used, thus needs to be
removed.

Subject: liquidio: replace info-pointer mode with buffer-pointer-only mode

Each Octeon output ring can DMA packets to host memory in two modes:  info-
pointer mode and buffer-pointer-only mode.  In info-pointer mode, Octeon
takes two buffer pointers for each packet and places the length of the
packet along with specified number of bytes from the beginning of the
packet into one buffer and the rest of the packet in a separate buffer.  In
buffer-pointer-only mode, Octeon takes single buffer pointer and places the
length of the packet at the beginning of the buffer followed by the packet
data.

This patch switches all Octeon output rings from info-pointer mode to
buffer-pointer-only mode.  This results in fewer DMA setups and cache line
snoops.

Subject: cxgb4: notify uP to route ctrlq compl to rdma rspq

During the module initialisation there is a possible race
(basically race between uld and lld) where neither the uld
nor lld notifies the uP about where to route the ctrl queue
completions. LLD skips notifying uP as the rdma queues were
not created by then (will leave it to ULD to notify the uP).
As the ULD comes up, it also skips notifying the uP as the
flag FULL_INIT_DONE is not set yet (ULD assumes that the
interface is not up yet).

Consequently, this race between uld and lld leaves uP
unnotified about where to send the ctrl queue completions
to, leading to iwarp RI_RES WR failure.

Here is the race:

CPU 0                                   CPU1

- allocates nic rx queus
- t4_sge_alloc_ctrl_txq()
(if rdma rsp queues exists,
tell uP to route ctrl queue
compl to rdma rspq)
                                - acquires the mutex_lock
                                - allocates rdma response queues
                                - if FULL_INIT_DONE set,
                                  tell uP to route ctrl queue compl
                                  to rdma rspq
                                - relinquishes mutex_lock
- acquires the mutex_lock
- enable_rx()
- set FULL_INIT_DONE
- relinquishes mutex_lock

This patch fixes the above issue.

Subject: net/mlx5e: Prevent PFC call for non ethernet ports

Port flow control supported only for ethernet ports,
therefore, prevent any call if the port type differs from
MLX5_CAP_PORT_TYPE_ETH.

Subject: net/mlx5e: Add new profile function update_carrier

Updating the carrier involves specific HW setting, each profile should
use its own function for that.

Both IPoIB and VF representor don't need carrier update function, since
VF representor has only a logical link to VF and IPoIB manages its own
link via ib_core upper layer.

Subject: net/mlx5e: Use hard_mtu as part of the mlx5e_priv struct

The mtu extra space that kept for the HW is specific for each link type,
and it is different in mlx5e and mlx5i modules.
Now it is kept in the priv structures, set by the mlx5e/mlx5i driver
accordingly.

independently, so add the infrastructure to provide it externally.

Subject: qed*: qede_roce.[ch] -> qede_rdma.[ch]

Once we have iWARP support, the qede portion of the qedr<->qede would
serve all the RDMA protocols - so rename the file to be appropriate
to its function.

While we're at it, we're also moving a couple of inclusions to it into
.h files and adding includes to make sure it contains all type
definitions it requires.

Subject: qed: SPQ async callback registration

Whenever firmware indicates that there's an async indication it needs
to handle, there's a switch-case where the right functionality is called
based on function's personality and information.

Before iWARP is added [as yet another client], switch over the SPQ into
a callback-registered mechanism, allowing registration of the relevant
event-processing logic based on the function's personality. This allows
us to tidy the code by removing protocol-specifics from a common file.

Subject: net-next: stmmac: dwmac-sun8i: force EPHY clock freq to 24MHz

The EPHY control part of the EMAC syscon register has a bit called
CLK_SEL. On the datasheet it says that if it's 0 the EPHY clock is 25MHz
and if it's 1 the clock is 24MHz.

However, according to the datasheets, no Allwinner SoC with EPHY has any
extra xtal input pins for the EPHY, and the system xtal is 24MHz.

That means the EPHY is not possible to get a 25MHz xtal input, and thus
the frequency can only be 24MHz.

It doesn't matter on H3 as the default value of H3 is 24MHz, however on
V3s the default value is wrongly set to 25MHz, which prevented the EPHY
from working properly.

Force the EPHY clock frequency to 24MHz.

Subject: net-next: stmmac: dwmac-sun8i: add support for V3s EMAC

Allwinner V3s SoC has an Ethernet MAC and an internal PHY like the ones
in H3 SoC, however the MAC has no external *MII interfaces available at
GPIOs, thus only MII connection to internal PHY is supported.

Add this variant of EMAC to dwmac-sun8i driver.

The default value of the syscon EMAC-related register seems to have
changed from H3, but it seems to be a harmless change.

Subject: net: dsa: mv88e6xxx: add irl_init_all op

Some Marvell chips have an Ingress Rate Limit unit. But the command
values slightly differs between models: 88E6352 use 3-bit for operations
while 88E6390 use different 2-bit operations.

This commit kills the IRL flags in favor of a new operation implementing
the "Init all resources to the initial state" operation.

This fixes the operation of 88E6390 family where 0x1000 means Read the
selected resource 0, register 0 on port 16, instead of init all.

A mv88e6xxx_irl_setup helper is added to wrap the operation call.

Subject: net: dsa: mv88e6xxx: clarify SMI PHY functions

Marvell chips with an SMI PHY access in Global 2 registers handle both
Clause 22 and Clause 45 of IEEE 802.3.

The 88E6390 family has addition bits to target the internal or external
PHYs connected to the device, and a Setup function in addition to the
default (register) Access function.

Prefix the SMI PHY Command and Data registers macros, implement clear
helpers for Clause 22 and 44 Access functions, rename variable to match
the SMI and switch vocabulary (device and register addresses for Clause
22 and port and device class for Clause 45.)

Finally do not use complex macros but simple 16-bit mask to document the
registers organization.

Subject: net: dsa: mv88e6xxx: prefix Global 2 Watchdog macros

The Marvell 88E6352 family has a Global 2 register dedicated to the
watchdog setup. But the 88E6390 turned it into an indirect table.

Prefix and document that.

representation of the register layout.

From a985343ba90635cda3f3704f71021254c91cebbd Mon Sep 17 00:00:00 2001
From: Matthias Schiffer <mschiffer@universe-factory.net>
Date: Mon, 19 Jun 2017 10:03:55 +0200
Subject: vxlan: refactor verification and application of configuration

The vxlan_dev_configure function was mixing validation and application of
the vxlan configuration; this could easily lead to bugs with the changelink
operation, as it was hard to see if the function wcould return an error
after parts of the configuration had already been applied.

This commit splits validation and application out of vxlan_dev_configure as
separate functions to make it clearer where error returns are allowed and
where the vxlan_dev or net_device may be configured. Log messages in these
functions are removed, as it is generally unexpected to find error output
for netlink requests in the kernel log. Userspace should be able to handle
errors based on the error codes returned via netlink just fine.

In addition, some validation and initialization is moved to vxlan_validate
and vxlan_setup respectively to improve grouping of similar settings.

Finally, this also fixes two actual bugs:

* if set, conf->mtu would overwrite dev->mtu in each changelink operation,
  reverting other changes of dev->mtu
* the "if (!conf->dst_port)" branch would never be run, as conf->dst_port
  was set in vxlan_setup before. This caused VXLAN-GPE to use the same
  default port as other VXLAN sockets instead of the intended IANA-assigned
  4790.

Subject: vxlan: improve validation of address family configuration

Address families of source and destination addresses must match, and
changelink operations can't change the address family.

In addition, always use the VXLAN_F_IPV6 to check if a VXLAN device uses
IPv4 or IPv6.

* Multicast addresses are never valid as local address
* Link-local IPv6 unicast addresses may only be used as remote when the
  local address is link-local as well
* Don't allow link-local IPv6 local/remote addresses without interface

We also store in the flags field if link-local addresses are used for the
follow-up patches that actually make VXLAN over link-local IPv6 work.

Subject: vxlan: fix snooping for link-local IPv6 addresses

If VXLAN is run over link-local IPv6 addresses, it is necessary to store
the ifindex in the FDB entries. Otherwise, the used interface is undefined
and unicast communication will most likely fail.

Support for link-local IPv4 addresses should be possible as well, but as
the semantics aren't as well defined as for IPv6, and there doesn't seem to
be much interest in having the support, it's not implemented for now.

Subject: vxlan: allow multiple VXLANs with same VNI for IPv6 link-local
 addresses

As link-local addresses are only valid for a single interface, we can allow
to use the same VNI for multiple independent VXLANs, as long as the used
interfaces are distinct. This way, VXLANs can always be used as a drop-in
replacement for VLANs with greater ID space.

This also extends VNI lookup to respect the ifindex when link-local IPv6
addresses are used, so using the same VNI on multiple interfaces can
actually work.

Subject: net-next: mediatek: add RX IRQ delay support

The PDMA engine used for RX allows IRQ aggregation. The patch sets up the
corresponding registers to aggregate 4 IRQs into one. Using aggregation
reduces the load on the core handling to a quarter thus reducing IRQ
latency and increasing RX performance by around 10%.

Subject: net-next: mediatek: split IRQ register locking into TX and RX

Originally the driver only utilised the new QDMA engine. The current code
still assumes this is the case when locking the IRQ mask register. Since
RX now runs on the old style PDMA engine we can add a second lock. This
patch reduces the IRQ latency as the TX and RX path no longer need to wait
on each other under heavy load.

Subject: net-next: mediatek: set the rx_queue to 0

The get_rps_cpu() function will not do any RPS on the data flow when no
queue is setup and always use the current cpu where the IRQ was handled
to also handle the backlog. As we only have one physical queue we always
set this to 0 unconditionally.

may not be initialized and directly calling the interrupt handler will

With -Wformat-truncation, gcc throws the following warning.

Fix this by increasing the size of devname to accommodate 15 character
netdev interface name and description.

Remove length format precision for %s. We can fit entire name.

Also increment the version.

Subject: s390/qeth: fix packing buffer statistics

There's two spots in qeth_send_packet() where we don't accurately
account for transmitted packing buffers in qeth's performance
statistics:

1) when flushing the current buffer due to insufficient size,
   and the next buffer is not EMPTY, we need to account for that
   flushed buffer.
2) when synchronizing with the TX completion code, we reset
   flush_count and thus forget to account for any previously
   flushed buffers.

Subject: s390/qeth: use diag26c to get MAC address on L2

When a s390 guest runs on a z/VM host that's part of a SSI cluster,
it can be migrated to a different host. In this case, the MAC address
it originally obtained on the old host may be re-assigned to a new
guest. This would result in address conflicts between the two guests.

When running as z/VM guest, use the diag26c MAC Service to obtain
a hypervisor-managed MAC address. The MAC Service is SSI-aware, and
won't re-assign the address after the guest is migrated to a new host.

This patch adds support for the z/VM MAC Service on L2 devices.

Subject: i40e: add support for XDP_TX action
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch adds proper XDP_TX action support. For each Tx ring, an
additional XDP Tx ring is allocated and setup. This version does the
DMA mapping in the fast-path, which will penalize performance for
IOMMU enabled systems. Further, debugfs support is not wired up for
the XDP Tx rings.

Subject: i40evf: assign num_active_queues inside i40evf_alloc_queues

The variable num_active_queues represents the number of active queues we
have for the device. We assign this pretty early in i40evf_init_subtask.

Several code locations are written with loops over the tx_rings and
rx_rings structures, which don't get allocated until
i40evf_alloc_queues, and which get freed by i40evf_free_queues.

These call sites were written under the assumption that tx_rings and
rx_rings would always be allocated at least when num_active_queues is
non-zero.

Lets fix this by moving the assignment into the function where we
allocate queues. We'll use a temporary variable for storage so that we
don't assign the value in the adapter structure until after the rings
have been set up.

Finally, when we free the queues, we'll clear the value to ensure that
we do not loop over the rings memory that no longer exists.

This resolves a possible NULL pointer dereference in
i40evf_get_ethtool_stats which could occur if the VF fails to recover
from a reset, and then a user requests statistics.

Subject: i40e: use dev_dbg instead of dev_info when warning about missing
 routine

When searching for the vf_capability client routine, dev_info() was
used, instead of the normal dev_dbg(). This causes the message to be
displayed at standard log levels which can cause administrators to
worry. Avoid this by using dev_dbg instead.

Subject: i40e: comment that udp_port must be in host byte order

The firmware expects the port number passed when setting up
the UDP tunnel configuration to be in Little Endian format.
The i40e_aq_add_udp_tunnel command byte swaps the value from
host order to Little Endian.

Since commit fe0b0cd97b4f ("i40e: send correct port number to
AdminQ when enabling UDP tunnels") we've correctly
sent the value in host order.

Let's also add a comment to the function explaining that it must
be in host order, as the port numbers are commonly stored as Big
Endian values.

The fix makes sure that the array is not accessed past the size of

Changes parsing of FW 4.33 AQ command Get CEE DCBX OPER CFG (0x0A07).
Change is required because FW now creates the oper_prio_tc

This change will only apply to FW 4.33 as future FW versions will use a

Subject: i40e: genericize the partition bandwidth control

Partition bandwidth control is not in just one form of MFP (multi-function
partitioning), so make the code more generic and be sure to nudge the Tx
scheduler for all MFP.

Subject: i40e: fix disabling overflow promiscuous mode

There exists a bug in which the driver does not correctly exit overflow
promiscuous mode.  This can occur if "too many" mac filters are added,
putting the driver into overflow promiscuous mode, and the filters are
then removed.  When the failed filters are removed, the driver reports
exiting overflow promiscuous mode which is correct, however traffic
continues to be received as if in promiscuous mode still.

The bug occurs because the conditional for toggling promiscuous mode was
set to only execute when promiscuous mode was enabled and not when it
was disabled as well.  This patch fixes the conditional to correctly
execute when promiscuous mode is toggled and not just enabled.  Without
this patch, the driver is unable to correctly exit overflow promiscuous
mode.

Subject: i40e: clear only cause_ena bit

When disabling interrupts, we should only be clearing the CAUSE_ENA bit,
not clearing the whole register.  Clearing the whole register sets the
NEXTQ_IDX field to 0 instead of 0x7ff which can confuse the Firmware in
some reset sequences.

Subject: i40e: Handle PE_CRITERR properly with IWARP enabled

When IWARP is enabled, we weren't clearing the PE_CRITERR, just logging
it and removing it from the mask. We need to do a corer to reset the
PE_CRITERR register, so set the bit for that as we handle the
interrupt.

We should also be checking for the error against the PFINT_ICR0 register,
and only need to clear it in the value getting written to
PFINT_ICR0_ENA.

Subject: i40e: don't hold RTNL lock for the entire reset

We recently refactored i40e_do_reset() and its friends to be able to
hold the RTNL lock only for the portions that actually need to be
protected. However, a separate refactoring added several new callers of
these functions during the PCIe error recovery and suspend/resume
cycles.

When merging the changes together, it was not noticed that we could
reduce the RTNL scope by letting the reset function handle the lock
itself, as previously it was not possible.

Fix this by replacing these call sites to indicate that the reset
function should handle its own lock. This enables multiple PFs to reset
or resume simultaneously without serializing the resets via the RTNL
lock. The end result is that on systems with lots of PFs and VFs the
resets don't stall waiting for each other to finish.

It is probable that we can also do the same for i40e_do_reset_safe, but
this author did not research that change carefully enough to be
confident.

Subject: ath10k: use complete VHT chan width for 160MHz workaround

The ath10k firmware doesn't announce its VHT channel width capabilities in
the vht_cap information from the "service ready event" arguments. The
driver must therefore check whether the 160MHz short GI bit is set and
whether the driver still doesn't set the bits for the 160/80+80 MHz
capabilities.

The two bits for the channel width are a two bit integer and not two
separate bits which cannot be parsed without the knowledge of the other
bit. Using IEEE80211_VHT_CAP_SUPP_CHAN_WIDTH_160_80PLUS80MHZ (b10..) as a
mask for this task doesn't make any sense. The correct mask for the VHT
channel width should be used instead to make this check more readable.

Subject: ath10k: configure rxnss_override for QCA9984

QCA9984 hardware can do 4x4 at 80Mhz, but only 2x2 at 160Mhz.

First, report this to user-space by setting the max-tx-speed
and max-rx-speed vht capabilities.

Second, if the peer rx-speed is configured, and if we
are in 160 or 80+80 mode, and the peer rx-speed matches
the max speed for 2x2 or 1x1 at 160Mhz (long guard interval),
then use that info to set the peer_bw_rxnss_override appropriately.

Without this, a 9984 firmware will not use 2x2 ratesets when
transmitting to peer (it will be stuck at 1x1), because
the firmware would not have configured the rxnss_override.

Subject: ath10k: set rxnss_override for QCA9888

QCA9888 supports VHT80 with 2x2. But it only support 1x1 with VHT160 or
VHT80+80. Inform userspace and the the QCA firmware about that limitation
whenever VHT80+80 or VHT160 is configured.

Subject: wil6210: prevent platform callbacks after uninit

After calling platform_ops.uninit() it is still possible to invoke
platform callbacks.
To prevent this, zero platform_ops right after invoking uninit.

Subject: wil6210: add support for PCIe D3hot in system suspend

In order to preserve the connection in suspend/resume flow,
wil6210 host allows going to PCIe D3hot state in suspend,
instead of performing a full wil6210 device reset. This
requires the platform ability to initiate wakeup in case of
RX data. To check that, a new platform API is added.
In addition, add cfg80211 suspend/resume callbacks
implementation.

Subject: brcmfmac: Use separate firmware for revision 0 of the brcm43430 chip

The brcm43430 chip needs different firmware files for chip revision 0
and 1. The file currently in linux-firmware is for revision 1 only.

This commit makes brcmfmac request brcmfmac43430a0-sdio.bin instead
of brcmfmac43430-sdio.bin for revision 0 chips.

Note that the behavior for revision 1 chips is not changed, ideally those
would load brcmfmac43430a1-sdio.bin, but that will break existing setups.

Subject: mwifiex: fixes the unexpected be printed log by default

This patch uses WARN level is not printed by default.

In some cases, some boards have always met the unused log be printed as
follows.
...
[23193.523182] mwifiex_pcie 0000:01:00.0: mwifiex_get_cfp:
cannot find cfp by band 2    & channel=13 freq=0
[23378.633684] mwifiex_pcie 0000:01:00.0: mwifiex_get_cfp:
cannot find cfp by band 2    & channel=13 freq=0

Due to we used the wifi default area was US and didn't support 12~14
channels. As Frequencies:
* 2412 MHz [1] (30.0 dBm)
* 2417 MHz [2] (30.0 dBm)
* 2422 MHz [3] (30.0 dBm)
* 2427 MHz [4] (30.0 dBm)
* 2432 MHz [5] (30.0 dBm)
* 2437 MHz [6] (30.0 dBm)
* 2442 MHz [7] (30.0 dBm)
* 2447 MHz [8] (30.0 dBm)
* 2452 MHz [9] (30.0 dBm)
* 2457 MHz [10] (30.0 dBm)
* 2462 MHz [11] (30.0 dBm)
* 2467 MHz [12] (disabled)
* 2472 MHz [13] (disabled)
* 2484 MHz [14] (disabled)

Also, as the commit 1b499cb72f26b
("mwifiex: disable channel filtering feature in firmware"), it proved to
be a feature to get better scan result from overlapping channel.

Even there could be AP from overlapping channel (might be 12/13/14
in this case), it will be filtered depend on reg domain rules.
e.g:
...
if (ch->flags & IEEE80211_CHAN_DISABLED)
        continue;

So it should not been an ERROR, use the WARN level to instead it for now.

Subject: rsi: Register interrupt handler before firmware load

Before firmware load, sometimes false interrupts are received.
System hang is observed if interrupt handler is not registered
to receive these interrupts. Hence interrupt handler registration
is moved before firmware load. We will drop these false interrupts
as these are not from the device.

Subject: rsi: add tx frame for common device configuration

After successful loading of firmware, a CARD READY indication is
received by host. Common device configuration parameters are sent
to the device after this. It includes information like device
operating mode (Wi-Fi alone or BT coex), power save related
parameters, GPIO information etc. As device supports BT coex,
this frame is send in COEX queue initially. Based on the operating
mode, CARD READY indication is received from each protocol module
in firmware i.e. WLAN, BT.

Subject: rtlwifi: btcoex: set correct interface type and parameter.

This commit fixies two problems. The first one is interface types
(e.g. PCI) that are used to switch antenna, and the second is to add
wifi_only parameter to give correct state.

Subject: rtlwifi: Correct power save capability while init mac80211

Since the driver itself will enter power saving mode dynamically
according to the traffic, we set hw capability SUPPORTS_PS and
SUPPORTS_DYNAMIC_PS in case of fwctrl_lps.

The process IEEE80211_CONF_CHANGE_PS in op_config is used by
SW-LPS only, so we add constraints to avoid errors.

Subject: rtlwifi: Add TX report and disable key to force wait until report
 acked.

When using EAPOL to do a PTK rekey, there is a possible race condition.
When msg 3/4 is received, the supplicant will send msg 4/4 and install
the new key immediately; however, the driver must make sure that msg 4/4
is sent before installing the new key. We use TX report to ensure it is
sent.

Subject: brcmfmac: initialize oob irq data before request_irq()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This fixes spin-forever in irq handler when IRQ is already asserted
at request_irq() time.

Subject: qed: Duplicate qed_roce.[ch] to qed_rdma.[ch]

This patch adds files that will contain common code for RoCE/iWARP.
The files are currently identical to qed_roce.c / qed_roce.h and
intentionally not added to the makefile. The next patch in the series
will modify the files so that roce specific code is left in qed_roce
and common roce/iwarp code will be placed in qed_rdma

This patch is the result of a simple
cp qed_rdma.c qed_roce.c
cp qed_rdma.h qed_roce.h

From b71b9afdf6d6c1ca728fde2aa14bc71721cab34e Mon Sep 17 00:00:00 2001
From: "Kalderon, Michal" <Michal.Kalderon@cavium.com>
Date: Wed, 21 Jun 2017 16:22:45 +0300
Subject: qed: Split rdma content between qed_rdma and qed_roce

This patch places common iWARP / RoCE code in qed_rdma
and roce specific code in qed_roce

There is one new function ( qed_roce_setup ) added, the rest
of the patch removes content from the files and removes some
static definitions.

From 7003cdd6a121e7bdb8a05eb1931f9549a36ea723 Mon Sep 17 00:00:00 2001
From: "Kalderon, Michal" <Michal.Kalderon@cavium.com>
Date: Wed, 21 Jun 2017 16:22:46 +0300
Subject: qed*: Rename qed_roce_if.h to qed_rdma_if.h

Rename the qed_roce_if file to qed_rdma_if as it
represents a common interface for RoCE and iWARP.

this commit affects RDMA/qedr as well.

Subject: net/mlx5e: Build SKB with exact frag_size

Build the SKB over the receive packet instead of the
whole page. Getting the SKB's linear data and shared_info
closer improves locality.
In addition, this opens up the possibility to make use of
other parts of the page in the downstream page-reuse patch.

Subject: net/mlx5e: Enhance RX SKB headroom logic

In the RX memory scheme of non Striding RQ, we use linear SKBs.
Keeping NET_IP_ALIGN in headroom can improve performance on some archs.
In addition, take this headroom into account when calculating the
LRO WQE size.

These are not needed in Striding RQ as they're done implicitly
within the non-linear SKB allocation.

Subject: net/mlx5e: Introduce RX Page-Reuse

Introduce a Page-Reuse mechanism in non-Striding RQ RX datapath.

A WQE (RX descriptor) buffer is a page, that in most cases was fully
wasted on a packet that is much smaller, requiring a new page for
the next round.

In this patch, we implement a page-reuse mechanism, that resembles a
`SW Striding RQ`.
We allow the WQE to reuse its allocated page as much as it could,
until the page is fully consumed.  In each round, the WQE is capable
of receiving packet of maximal size (MTU). Yet, upon the reception of
a packet, the WQE knows the actual packet size, and consumes the exact
amount of memory needed to build a linear SKB. Then, it updates the
buffer pointer within the page accordingly, for the next round.

Feature is mutually exclusive with XDP (packet-per-page)
and LRO (session size is a power of two, needs unused page).

Performance tests:
iperf tcp tests show huge gain:

Subject: net/mlx5e: Relocate the TC match on ip tos offload code section

The code section for offloading matches on ip tos (L3) should come
before and not after the one that deals with tcp/udp (L4) matches.

Otherwise, we might come up with wrong min-inline requirement, when
one attempts to match on both L3 and L4.

Fixes: fd7da28b280d ('net/mlx5e: Offload TC matching on ip tos / traffic-class')

Subject: net/mlx5e: Offload TC matching on ip ttl

Enable offloading of TC matching on ip ttl / hop-limit

As matching on ttl is supported only by newer HW brands (ConnectX-5),
we should do capability check before attempting to offload that.

Subject: net/mlx5e: Use macro for TC header re-write offload field mapping

Use a macro for the static mapping between the enumeration of field
supported by the firmware for header re-write to the corresponding
network header field. This improves the readability of the code and
doesn't change any functionality.

Subject: net/mlx5e: Support the flash device ethtool callback

This callback further invokes the mlxfw module to flash the new
firmware file to the device.

As the firmware flash process takes about 20 seconds and ethtool
takes the rtnl lock during the flash_device callback, we release
the rtnl lock at the beginning of the flash process and take it
again before leaving the callback.

This way, rtnl is not held during the process. To make sure the
device does not get deleted while being flashed, we take a
reference to it before releasing rtnl lock.

Date: Wed, 21 Jun 2017 14:53:01 -0500
Subject: ibmvnic: Fix error handling when registering long-term-mapped buffers

The patch stores the return code of the REQUEST_MAP_RSP sub-CRQ command
in the private data structure, where it can be later checked during
device open or a reset.

In the case of a reset, the mapping request to the vNIC Server may fail,
especially in the case of a partition migration. The driver attempts to
handle this by re-allocating the buffer and re-sending the mapping request.

The original error handling implementation was removed. The separate
function handling the REQUEST_MAP response message was also removed,
since it is now simple enough to be handled in the ibmvnic_handle_crq
function.

Subject: ibmvnic: Correct return code checking for ibmvnic_init during probe

The update to ibmvnic_init to allow an EAGAIN return code broke
the calling of ibmvnic_init from ibmvnic_probe. The code now
will return from this point in the probe routine if anything
other than EAGAIN is returned. The check should be to see if rc
is non-zero and not equal to EAGAIN.

Without this fix, the vNIC driver can return 0 (success) from
its probe routine due to ibmvnic_init returning zero, but before
completing the probe process and registering with the netdev layer.

Subject: hv_netvsc: Fix the carrier state error when data path is off

When the VF NIC is opened, the synthetic NIC's carrier state is set to
off. This tells the host to transitions data path to the VF device. But
if startup script or user manipulates the admin state of the netvsc
device directly for example:
        # ifconfig eth0 down
	# ifconfig eth0 up
Then the carrier state of the synthetic NIC would be on, even though the
data path was still over the VF NIC. This patch sets the carrier state
of synthetic NIC with consideration of the related VF state.

Subject: net: mvpp2: add comments about smp_processor_id() usage

A previous commit modified a number of smp_processor_id() used in
migration-enabled contexts into get_cpu/put_cpu sections. However, a few
smp_processor_id() calls remain in the driver, and this commit adds
comments explaining why they can be kept.

When all a function does is calling another function with the exact same
arguments, in the exact same order, you know it's time to remove said
function. Which is exactly what this commit does.

Subject: iwlwifi: remove resp_pkt NULL checks

Contrary to what some of the comments say, if rfkill was
asserted the transport will return -ERFKILL instead of
success, if CMD_WANT_SKB was set, so it's not necessary
to check cmd.resp_pkt for being NULL if the return code
was success.

Validate that this is true in iwl_trans_send_cmd().

Most of the other code modifications were done with the
following spatch:
    @@
    struct iwl_host_cmd cmd;
    identifier pkt;
    @@
    <...
    (
    pkt = cmd.resp_pkt;
    ...
    -if (!pkt) { ... }
    |
    pkt = cmd.resp_pkt;
    ...
    -if (WARN_ON(!pkt)) { ... }
    |
    -if (!cmd.resp_pkt) { ... }
    )
    ...>

If FW isn't alive, trying to collect debug data will
result in errors both in driver and in the collected

Subject: iwlwifi: mvm: avoid unnecessary cache trashing in Tx path

When sending a Tx Command with a Tx packet, we allocate the
Tx command separately from the payload of the packet.
The WiFi MAC header is then copied into the buffer that was
allocated for the Tx Command. This means that this buffer
needs to be big enough to contain both. This is why it is
allocated with iwl_trans_alloc_tx_cmd which returns a
pointer to a newly allocated not zeroed struct
iwl_device_cmd.

The Tx command has a few bit fields and hence it needs to
be zeroed, but all the rest of the buffer doesn't need to
be zeroed since it will either be memcopy'ed with the MAC
header, or not even sent to the device.
This means that we don't need to zero all the
iwl_device_cmd structure, but rather only the size of
the iwl_tx_cmd structure.

Since sizeof(iwl_tx_cmd) - sizeof(iwl_tx_cmd) is about
260 bytes, this can avoid touching 4 cache lines for each
packet.

Subject: iwlwifi: mvm: use scnprintf() instead of snprintf()

It's safer to use scnprintf() here because the buffer might
be too short for the full format strings. In most cases
this isn't true because of external limits on the values.

In one case, this fixes a stack data leak.

Subject: iwlwifi: mvm: track and report IBSS manager status to mac80211

Shaul reported that when iwlmvm was sending beacons, it didn't properly
also take ownership of the probe responses. This is because the whole
mac80211 callback (tx_last_beacon) wasn't implemented. Fix that to make
IBSS discovery work better.

There is no need to send D0I3_END_CMD as ASYNC during the system
resume flow.  Additionally, the other flags used are meaningless in
this case (they were just copied from the runtime resume flow), so
remove them all.

Subject: iwlwifi: mvm: support D0I3_END_CMD at the start of resume

New FW versions require the D0I3_END_CMD to be sent as the first
command to the FW in the resume flow.  If the TLV is set, send that
command first, otherwise keep the original behavior (i.e. send last).

Subject: iwlwifi: mvm: make iwl_mvm_update_mcc() easier to follow

Some static checkers (e.g. smatch) complain about the logic, saying that
resp_cp might be leaked. Clearly that isn't true, but making the logic
easier to follow does not result in any significant code changes and makes
the code more readable by moving the NULL check closer to its source.

Subject: iwlwifi: mvm: don't warn in queue sync on RF-kill

If we happen to be in or get into the queue sync when RF-kill
is asserted, we return from there and warn since there are
still queue sync notifications outstanding. These can't ever
come though, because we're in RF-kill, so don't WARN then.

While at it, also move the warning to the appropriate place,
if the request is not synchronous then we shouldn't warn, but
currently always will.

To make it fast, also trigger the waitq when on rfkill assert.

Subject: iwlwifi: pcie: don't report RF-kill enabled while shutting down

When toggling the RF-kill pin quickly in succession, the driver can
get rather confused because it might be in the process of shutting
down, expecting all commands to go through quickly due to rfkill,
but the transport already thinks the device is accessible again,
even though it previously shut it down. This leads to bugs, and I
even observed a kernel panic.

Avoid this by making the PCIe code only report that the radio is
enabled again after the higher layers actually decided to shut it
off.

This also pulls out this common RF-kill checking code into a common
function called by both transport generations and also moves it to
the direct method - in the internal helper we don't really care
about the RF-kill status anymore since we won't report it up until
the stop anyway.

We don't actually care about the value at all, just making sure
that we can successfully parse a single integer value, but that's
entirely pointless - remove it.

Subject: iwlwifi: mvm: support aggregations on A000 HW

On A000 HW, the SCD rdptr has only 8 bits allocated
for it, thus when checking if a queue is full, or
when checking if the SSN is equal to the TID's
next_reclaimed, A000 HW should trim the SSN.

Fix this by "normalizing" the SSN to wrap around
0xFF when comparing to the next_reclaimed on A000
HW.

Subject: NFC: pn544: Switch to devm_acpi_dev_add_driver_gpios()

Switch to use managed variant of acpi_dev_add_driver_gpios() to simplify
error path and fix potentially wrong assignment if ->probe() fails.

Subject: NFC: st21nfca: Add GPIO ACPI mapping table

In order to make GPIO ACPI library stricter prepare users of
gpiod_get_index() to correctly behave when there no mapping is
provided by firmware.

Here we add explicit mapping between _CRS GpioIo() resources and
their names used in the driver.

Legacy platform data must go away. We are on the safe side here since
there are no users of it in the kernel.

If anyone by any odd reason needs it the GPIO lookup tables and
built-in device properties at your service.

Subject: NFC: st-nci: Get rid of "interesting" use of interrupt polarity

I2C and SPI frameworks followed by IRQ framework do set
interrupt polarity correctly if it's properly specified in firmware
(ACPI or DT).

Get rid of the redundant trick when requesting interrupt.

Subject: NFC: st-nci: Covert to use GPIO descriptor

Since we got rid of platform data, the driver may use GPIO descriptor
directly.

Looking deeply to the use of the GPIO pin it looks like it should be
a GPIO based reset control rather than custom GPIO handling. But this
is out of scope of the change.

Subject: NFC: st-nci: Add GPIO ACPI mapping table

In order to make GPIO ACPI library stricter prepare users of
gpiod_get_index() to correctly behave when there no mapping is
provided by firmware.

Here we add explicit mapping between _CRS GpioIo() resources and
their names used in the driver.

The "or" condition (clk_freq != TRF7970A_27MHZ_CLOCK_FREQUENCY) ||
(clk_freq != TRF7970A_13MHZ_CLOCK_FREQUE) will always be true because
clk_freq cannot be equal to two different values at the same time. Use
the  && operator instead of || to fix this.

Subject: Revert "NFC: trf7970a: Handle extra byte in response to Type 5 RMB
 commands"

This reverts commit ab714817d7e891608d31f6996b1e4c43cf2bf342.

The original commit was designed to handle a bug in the trf7970a NFC
controller where an extra byte was returned in Read Multiple Blocks (RMB)
command responses.  However, it has become less clear whether it is a bug
in the trf7970a or in the tag.  In addition, it was assumed that the extra
byte was always returned but it turns out that is not always the case. The
result is that a byte of good data is trimmed off when the extra byte is
not present ultimately causing the neard deamon to fail the read.

Since the trf7970a driver does not have the context to know when to trim
the byte or not, remove the code from the trf7970a driver all together
(and move it up to the neard daemon).  This has the added benefit of
simplifying the kernel driver and putting the extra complexity into
userspace.

Subject: iwlwifi: fix TX tracing for non-linear SKBs

When sending non-linear SKBs that should be included in the regular
TX tracing completely (and not be pushed into the tx_data tracing),
the (tracing) code didn't correctly take the fact that they were
non-linear into account and added only the skb head portion.

This probably never really triggered, since those frames we want
traced fully are most likely linear anyway, but the code gets easier
to understand and we lose an argument to the tracing function, so
overall fixing this is better.

Subject: iwlwifi: pcie: fix command completion name debug

When the command name is printed on command completion, the wrong
group is used, leading to the wrong name being printed. Fix this
by using the group ID without inappropriately mangling it through
iwl_cmd_groupid() - it's already a u8. Also, while at it, use it
from the same place as the command ID, everything else is just
confusing.

Note: This fix is only for DRAM collection mode.
      For other modes, an additional fix will be

Subject: iwlwifi: mvm: fix the recovery flow while connecting

In BSS mode in the disconnection flow, mac80211 removes
the AP station before the vif is set to unassociated.
Our firmware wants it the other way around: first set
the vif as unassociated, and then remove the AP station.

In order to bridge between those two different behaviors,
iwlmvm doesn't remove the station from the firmware when
mac80211 removes it, but only after the vif is set to
unassociated. The implementation is in
iwl_mvm_bss_info_changed_station:

if (assoc state was modified && mvmvif->ap_sta_id is VALID
    && assoc state is now UNASSC)
	remove_the_station_from_the_firmware()

During the recovery flow, mac80211 re-adds the AP station
and then reconfigures the vif. Since the vif is not
associated, and then, we enter the if above (which was
intended to be taken in the disconnection flow only) and
remove the station we just added. This defeats the
recovery flow.

Fix this by not removing the AP station in this flow if
we are in recovery flow.

not involved, so we don't need it.

Subject: iwlwifi: mvm: reset the HW before dumping if HW error is detected

If the hardware is stuck, we can't read any of the memory we need to
dump it, so we end up printing only 0xa5a5a5a5, which is useless.

To solve this, poke the hardware by triggering a reset and re-enabling
the clocks if we detect a HW error.

Subject: iwlwifi: add a W/A for a scheduler hardware bug

In case we need to move the scheduler write pointer by
steps of 0x40, 0x80 or 0xc0, the scheduler gets stuck.
This leads to hardware error interrupts with status:
0x5A5A5A5A or alike.

In order to work around this, detect in the transport
layer that we are going to hit this case and tell iwlmvm
to increment the sequence number of the packets. This
allows to keep the requirement that the WiFi sequence
number is in sync with the index in the scheduler Tx queue
and it also allows to avoid the problematic sequence.
This means that from time to time, we will start a queue
from ssn + 1, but that shouldn't be a problem since we
don't switch to new queues for AMPDU now that we have
DQA which allows to keep the same queue while toggling
the AMPDU state.

This bug has been fixed on 9000 devices and up.

This new API allows flushing queues based on station ID and TID in A000

for 32 queues, which is not enough for A000 devices.

It's sometimes hard to find out which HW address the iwlwifi device is

easier, print out an info level message with the HW address as soon as
we know it.

Subject: iwlwifi: pcie: reduce unwanted noise in the logs

The driver prints "L1 Enabled - LTR Enabled" all the time as dev_info,
which is just useless noise in most cases.  Convert this to
IWL_DEBUG_POWER() so we don't pollute the log unnecessarily but still
can get this info on demand.

Subject: iwlwifi: pcie: delete the Tx queue timer earlier upon firmware crash

When the firmware crashes, the transmit queues can't make
any progress. This is why we stop the counter that monitor
the transmit queues' activity.
The call that notifies the error to the op_mode may take
a bit of time, so stop the timer of the transmit queues
earlier.

Subject: iwlwifi: pcie: work around suspend/resume issue

In some platforms, having the device enabled with certain radio
frontends causes the platform to not be able to resume properly
from suspend, regardless of the wakeup cause. This was traced to
a hardware issue with the integrated 9000-series A-step variant.
Set the right hardware bit to disable the problematic state.

Subject: iwlwifi: mvm: support TX on MONITOR iface

When trying to TX through a monitor interface, the
conditions in iwl_mvm_tx_skb_non_sta() don't match
and the frame tries to go out from an usued TXQ.

Add a check for monitor iface, and use the AUX queue
in such a case.

In non-DQA mode the frame is sent through the
static-allocated queues anyway, so the problem is
in DQA mode only.

Subject: nfp: xdp: move driver XDP setup into a separate function

In preparation of XDP offload flags move the driver setup into
a function.  Otherwise the number of conditions in one function
would make it slightly hard to follow.  The offload handler may
now be called with NULL prog, even if no offload is currently
active, but that's fine, offload code can handle that.

Subject: nfp: bpf: don't offload XDP programs in DRV_MODE

DRV_MODE means that user space wants the program to be run in
the driver.  Do not try to offload.  Only offload if no mode
flags have been specified.

Remember what the mode is when the program is installed and refuse
new setup requests if there is already a program loaded in a
different mode.  This should leave it open for us to implement
simultaneous loading of two programs - one in the drv path and
another to the NIC later.

Subject: nfp: bpf: release the reference on offloaded programs

The xdp_prog member of the adapter's data path structure is used
for XDP in driver mode.  In case a XDP program is loaded with in
HW-only mode, we need to store it somewhere else.  Add a new XDP
prog pointer in the main structure and use that when we need to
know whether any XDP program is loaded, not only a driver mode
one.  Only release our reference on adapter free instead of
immediately after netdev unregister to allow offload to be disabled
first.

Subject: net: stmmac: make some functions static

The functions dwmac4_dma_init_rx_chan, dwmac4_dma_init_tx_chan and
dwmac4_dma_init_channel do not need to be in global scope, so them
static.

Cleans up sparse warnings:
"symbol 'dwmac4_dma_init_rx_chan' was not declared. Should it be static?"
"symbol 'dwmac4_dma_init_tx_chan' was not declared. Should it be static?"
"symbol 'dwmac4_dma_init_channel' was not declared. Should it be static?"

Subject: net: ena: add hardware hints capability to the driver

With this patch, ENA device can update the ena driver about
the desired timeout values:
These values are part of the "hardware hints" which are transmitted
to the driver as Asynchronous event through ENA async
event notification queue.

In case the ENA device does not support this capability,
the driver will use its own default values.

Subject: net: ena: add support for out of order rx buffers refill

ENA driver post Rx buffers through the Rx submission queue
for the ENA device to fill them with receive packets.
Each Rx buffer is marked with req_id in the Rx descriptor.

Newer ENA devices could consume the posted Rx buffer in out of order,
and as result the corresponding Rx completion queue will have Rx
completion descriptors with non contiguous req_id(s)

In this change the driver holds two rings.
The first ring (called free_rx_ids) is a mapping ring.
It holds all the unused request ids.
The values in this ring are from 0 to ring_size -1.

When the driver wants to allocate a new Rx buffer it uses the head of
free_rx_ids and uses it's value as the index for rx_buffer_info ring.
The req_id is also written to the Rx descriptor

Upon Rx completion,
The driver took the req_id from the completion descriptor and uses it
as index in rx_buffer_info.
The req_id is then return to the free_rx_ids ring.

This patch also adds statistics to inform when the driver receive out
of range or unused req_id.

Note:
free_rx_ids is only accessible from the napi handler, so no locking is
required

Subject: net: ena: allow the driver to work with small number of msix vectors

Current driver tries to allocate msix vectors as the number of the
negotiated io queues. (with another msix vector for management).
If pci_alloc_irq_vectors() fails, the driver aborts the probe
and the ENA network device is never brought up.

With this patch, the driver's logic will reduce the number of IO
queues to the number of allocated msix vectors (minus one for management)
instead of failing probe().

Subject: cxgb4: Update T6 Buffer Group and Channel Mappings

We were using t4_get_mps_bg_map() for both t4_get_port_stats()
to determine which MPS Buffer Groups to report statistics on for a given
Port, and also for t4_sge_alloc_rxq() to provide a TP Ingress Channel
Congestion Map.  For T4/T5 these are actually the same values (because they
are ~somewhat~ related), but for T6 they should return different values
(T6 has Port 0 associated with MPS Buffer Group 0 (with MPS Buffer Group 1
silently cascading off) and Port 1 is associated with MPS Buffer Group 2
(with 3 cascading off)).

Subject: cxgb4: Use Firmware params to get buffer-group map

Buffer group mappings can be obtained using FW_PARAMs cmd for newer FW.

Since some of the bg_maps are obtained in atomic context, created another
t4_query_params_ns(), that wont sleep when awaiting mbox cmd completion.

Add app callback for reporting eswitch mode.  Non-SRIOV apps
should not implement this callback, nfp_app code will then
respond with -EOPNOTSUPP.

Subject: nfp: map mac_stats and vf_cfg BARs

If present map mac_stats and vf_cfg BARs. These will be used by
representor netdevs to read statistics for phys port and vf representors.

Also provide defines describing the layout of the mac_stats area.
Similar defines are already present for the cf_cfg area.

Based in part on work by Jakub Kicinski.

Subject: nfp: app callbacks for SRIOV

Add app-callbacks for app-specific initialisation of SRIOV.

Disabling SRIOV is brought forward in nfp_pci_remove()
so that nfp_app_sriov_disable is called while the app still exists.

This is intended to be used to implement representor netdevs for virtual
ports.

Subject: nfp: provide nfp_port to of nfp_net_get_mac_addr()

Provide port rather than vNIC as parameter of nfp_net_get_mac_addr.
This is to allow this function to be used by representor netdevs where
a vNIC may have more than one physical port none of which are associated
with the vNIC.

Subject: nfp: add flower app

Add app for flower offload. At this point the PF netdev and phys port
representor netdevs are initialised. Follow-up work will add support for
VF and PF representors and beyond that offloading the flower classifier.

Based in part on work by Benjamin LaHaise and Bert van Leeuwen.

Subject: net: qcom/emac: do not reset the EMAC during initialization

On ACPI systems, the driver depends on firmware pre-initializing the
EMAC because we don't have access to the clocks, and the EMAC has specific
clock programming requirements.  Therefore, we don't want to reset the
EMAC while we are completing the initialization.

Subject: net/mlx5e: Fix TX carrier errors report in get stats ndo

Symbol error during carrier counter from PPCNT was mistakenly reported as
TX carrier errors in get_stats ndo, although it's an RX counter.

Fixes: 269e6b3af3bf ("net/mlx5e: Report additional error statistics in get stats ndo")

Subject: net/mlx5: Set interface flags before cleanup in unload_one

In load_one, the interface flags are changed from down to up,
only after initializing the interfaces.
In unload_one, the flags are changed from up to down before the
interface cleanup.

Change the cleanup order to be opposite to initialization order.

This fixes flag consistency between init and cleanup.

Subject: net/mlx5: Add reserved-gids support

Reserved GIDs are entries in the GID table in use by the mlx5_core
and its submodules (e.g. FPGA, SRIOV, E-Swtich, netdev).
The entries are reserved at the high indexes of the GID table.

A mlx5 submodule may reserve a certain amount of GIDs for its own use
during the load sequence by calling mlx5_core_reserve_gids, and must
also take care to un-reserve these GIDs when it closes.
Reservation is only allowed during the load sequence and before any
interfaces (e.g. mlx5_ib or mlx5_en) are up.

After reservation, a submodule may call mlx5_core_reserved_gid_alloc/
free to allocate entries from the reserved GIDs pool.

Reserve a GID table entry for every supported FPGA QP.

A later patch in the patchset will remove them from being reported to
IB core.
Another such patch will make use of these for FPGA QPs in Innova NIC.

Added lib/mlx5.h to serve as a library for mlx5 submodlues, and to
expose only public mlx5 API, more mlx5 library files will be added in
future submissions.

Subject: net/mlx5: Add support for multiple RoCE enable

Previously, only mlx5_ib enabled RoCE on the port, but FPGA needs it as
well.
Add support for counting number of enables, so that FPGA and IB can work
in parallel and independently.
Program the HW to enable RoCE on the first enable call, and program to
disable RoCE on the last disable call.

Subject: IB/mlx5: Respect mlx5_core reserved GIDs

Reserved gids are taken by the mlx5_core, report smaller GID table
size to IB core.

Set mlx5_query_roce_port's return value back to int. In case of
error, return an indication. This rolls back some of the change
in commit 50f22fd8ecf9 ("IB/mlx5: Set mlx5_query_roce_port's return value to void")

Change set_roce_addr to use gid_set function, instead of directly
sending the command.

Subject: net/mlx5: Make get_cqe routine not ethernet-specific

Move mlx5e_get_cqe routine to wq.h and rename it to
mlx5_cqwq_get_cqe.

This allows it to be used by other CQ users outside of the
ethernet driver code.

A later patch in this patchset will make use of it from
FPGA code for the FPGA high-speed connection.

Subject: net/mlx5: Add QP WQ support

A QP in ConnectX is a concatenation of RQ and SQ which share a QP-number
and work together.
Add support for allocating and managing the work-queue buffer for a QP, in
a similar way to how SQs and RQs are already supported.

Subject: net/mlx5: FPGA, Add FW commands for FPGA QPs

The FPGA QP is a high-bandwidth communication channel between the host
CPU and the FPGA device. It allows performing DMA operations between
host memory and the FPGA logic via the ConnectX chip.

Add ConnectX FW commands which create and manipulate FPGA QPs.

Subject: net/mlx5: FPGA, Add high-speed connection routines

An FPGA high-speed connection has two endpoints, an FPGA QP and a
ConnectX QP.
Add library routines to create and connect the endpoints of an
FPGA high-speed connection.

These routines allow creating and interacting with both types of
connections: Shell and Sandbox Unit (SBU).

Shell connection provides an interface to the FPGA's address space,
which includes the configuration space and the DDR.
Use of the shell connection will be introduced in a later patchset.

SBU connection provides a command and/or data interface to the
application-specific logic within the FPGA.
Use of the SBU connection will be introduced in a later patch in
this patchset.

Some struct definitions are added to a new header file sdk.h, which
will be extended in later patches in the patchset.
This header file will contain the in-kernel FPGA client driver API.

Subject: net/mlx5: FPGA, Add SBU bypass and reset flows

The Innova FPGA includes shell hardware and Sandbox-Unit (SBU) hardware.
The shell hardware is handled by mlx5_core itself, while the SBU is
handled by a client driver.

Reset the SBU to a well-known initial state when initializing a new
device, and set the FPGA to bypass mode when uninitializing a device.
This allows the client driver to assume that its device has been
reset when a new device is detected.

During SBU reset, the FPGA is put into SBU-bypass mode. In this mode
packets do not pass through the SBU, so it cannot affect the network
data stream at all.

A factory-image does not have an SBU, so skip these flows.

Subject: net/mlx5: FPGA, Add SBU infrastructure

Add interface to initialize and interact with Innova FPGA SBU
connections.
A client driver may use these functions to set up a high-speed DMA
connection with its SBU hardware logic, and send/receive messages
over this connection.

A later patch in this patchset will make use of these functions for
Innova IPSec offload in mlx5 Ethernet driver.

Add commands to retrieve Innova FPGA SBU capabilities, and to
read/write Innova FPGA configuration space registers and memory,
over internal I2C.

At high level, the FPGA configuration space is divided such:
 0x00000000 - 0x007fffff is reserved for the SBU
 0x00800000 - 0xffffffff is reserved for the Shell
0x400000000 - ...        is DDR memory

A later patchset will add support for accessing FPGA CrSpace and memory
over a high-speed connection. This is the reason for the ACCESS_TYPE
enumeration, which currently only supports I2C.

From bebb23e6cb02d2fc752905e39d09ff6152852c6c Mon Sep 17 00:00:00 2001
From: Ilan Tayari <ilant@mellanox.com>
Date: Tue, 25 Apr 2017 22:42:31 +0300
Subject: net/mlx5: Accel, Add IPSec acceleration interface

Add routines for manipulating the hardware IPSec SA database (SADB).

In Innova IPSec, a Security Association (SA) is added or deleted
via a command message over the SBU connection.
The HW then sends a response message over the same connection.

Add implementation for Innova IPSec (FPGA-based) hardware.

These routines will be used by the IPSec offload support in a later patch
However they may also be used by others such as RDMA and RoCE IPSec.

mlx5/accel is a middle acceleration layer to allow mlx5e and other ULPs
to work directly with mlx5_core rather than Innova FPGA or other mlx5
acceleration providers.

In this patchset we add Innova IPSec support and mlx5/accel delegates
IPSec offloads to Innova routines.

In the future, when IPSec/TLS or any other acceleration gets integrated
into ConnectX chip, mlx5/accel layer will provide the integrated
acceleration, rather than the Innova one.

Subject: net/mlx5e: IPSec, Innova IPSec offload infrastructure

Add Innova IPSec ESP crypto offload configuration paths.
Detect Innova IPSec device and set the NETIF_F_HW_ESP flag.
Configure Security Associations using the API introduced in a previous
patch.

Add Software-parser hardware descriptor layout
Software-Parser (swp) is a hardware feature in ConnectX which allows the
host software to specify protocol header offsets in the TX path, thus
overriding the hardware parser.
This is useful for protocols that the ASIC may not be able to parse on
its own.

Note that due to inline metadata, XDP is not supported in Innova IPSec.

From 899a59d301bc0ccd312dd23d58899cfbbc94bead Mon Sep 17 00:00:00 2001
From: Ilan Tayari <ilant@mellanox.com>
Date: Mon, 19 Jun 2017 14:04:36 +0300
Subject: net/mlx5e: IPSec, Add Innova IPSec offload RX data path

In RX data path, the hardware prepends a special metadata ethertype
which indicates that the packet underwent decryption, and the result of
the authentication check.

Communicate this to the stack in skb->sp.

Make wqe_size large enough to account for the injected metadata.

Support only Linked-list RQ type.

IPSec offload RX packets may have useful CHECKSUM_COMPLETE information,
which the stack may not be able to use yet.

instructs the hardware to perform cryptography.

In addition, fill Software-Parser segment in TX descriptor so
that the hardware may parse the ESP protocol, and perform TX
checksum offload on the inner payload.

Support GSO, by providing the inverse of gso_size in the metadata.
This allows the FPGA to update the ESP header (seqno and seqiv) on the
resulting packets, by calculating the packet number within the GSO
back from the TCP sequence number.

Note that for GSO SKBs, the stack does not include an ESP trailer,
unlike the non-GSO case.

Subject: brcmfmac: fix double free upon register_netdevice() failure

The function brcmf_net_attach() can only fail when register_netdevice()
fails. When this happens register_netdevice() calls priv_destructor, ie.
brcmf_cfg80211_free_netdev() freeing the vif instance. Also upon this
failure brcmf_net_attach() calls free_netdev(). However, callers are also
doing cleanup resulting in double free. In some places they need netdev
private space as it holds parameters to communicate with the device. So
we want to do the cleanup only in callers of brcmf_net_attach() by making
the following changes:

 - set priv_destructor after register_netdevice() succeeds.
 - remove call to free_netdev() in brcmf_net_attach().
 - call free_netdev() in brcmf_net_detach() for unregistered netdev.
 - add free_netdev() if brcmf_net_attach() fails for a created interface.

Fixes: cf124db566e6 ("net: Fix inconsistent teardown and release of private netdev state.")

handling path to free it in such a case.

Subject: Bluetooth: hci_bcm: Fix unwanted error reporting if no bcm dev

The hci_bcm proto is able to operate without bcm platform device linked
to its uart port. In that case, firmware can be applied, but there is
no power operation (no gpio/irq resources mgmt).

However, the current implementation breaks this use case because of
reporting a ENODEV error in the bcm setup procedure if bcm_request_irq
fails (which is the case if no bcm device linked).

Fix this by removing bcm_request_irq error forwarding.

Subject: nfp: explicitly check if application FW is loaded

We support application FW being either loaded automatically at
boot from flash or (more commonly) by the driver from disk.
If FW is not found on disk and nothing is preloaded users are
faced with this unintuitive error:

nfp 0000:04:00.0: nfp: Failed to find PF symbol _pf0_net_bar0

We can do better.  Since we rely on symbol table being present -
check early if it could be correctly read out of from the device
and if not print a more informative message.

Subject: nfp: move area mapping helper into nfpcore

nfp_net_map_area() is a helper for mapping areas of NFP memory
defined in nfp_net_main.c.  Move it to nfpcore to allow reuse
and rename accordingly.  Create an additional helper -
nfp_cpp_area_alloc_acquire() the opposite of already existing
nfp_cpp_area_release_free().

Move most of the helper for mapping RTsyms from nfp_net_main.c
to nfpcore.  Use the new helper directly for mapping MAC statistics,
since they don't need to include the PCIe interface ID in the symbol
name.

Subject: nfp: add nfp_app cleanup callback and make flower use it

Add a cleanup callback for undoing what app init callback did.
Make flower allocate its private structure on init and free
it from the new callback.

While at it remember to set the app pointer to NULL on the
error path to avoid any races while probe path unwinds.

Subject: nfp: spawn nfp_ports for PF and VF ports

nfp_port is an abstraction which is supposed to allow us sharing
code between different netdev types (vNIC vs repr).  Spawn ports
for PFs and VFs to enable this sharing.

Subject: nfp: move representors' struct net_device_ops to shared code

Apps shouldn't declare their own struct net_device_ops for
representors, this makes sharing code harder.  Add necessary
nfp_app callbacks and move the definition of representors'
struct net_device_ops to common code.

Subject: nfp: allow converting representor's netdev into nfp_port

Based on struct net_device_ops figure out if netdev is a nfp_repr.
Use this knowledge to convert netdev directly to nfp_port.

Subject: nfp: handle SR-IOV already enabled when driver is probing

We assumed that when we probe number of enabled VFs will be at 0.
This doesn't have to be the case for example if previous driver left
SR-IOV enabled due to some VFs being assigned.  Read the number of VFs
enabled.  Fail probe if it's above current FWs limit.

Subject: nfp: reorder SR-IOV config and nfp_app SR-IOV callbacks

We previously assumed that app callback can be guaranteed to be
executed before SR-IOV is actually enabled.  Given that we can't
guarantee that SR-IOV will be disabled during probe or that we
will be able to disable it on remove, we should reorder the callbacks.
We should also call the app's sriov_enable if SR-IOV was enabled
during probe.

Application FW must be able to disable VFs internally and not depend
on them being removed at PCIe level.

Subject: nfp: allocate a private workqueue for driver work

Since we grab pf->lock around pci_enable_sriov() we can no longer
safely queue work which may also grab that lock onto system workqueue.
pci_enable_sriov() will flush system workqueue as part to wait for VF
probing.

Subject: ath9k: fix tx99 use after free

One scenario that could lead to UAF is two threads writing
simultaneously to the "tx99" debug file. One of them would
set the "start" value to true and follow to ath9k_tx99_init().
Inside the function it would set the sc->tx99_state to true
after allocating sc->tx99skb. Then, the other thread would
execute write_file_tx99() and call ath9k_tx99_deinit().
sc->tx99_state would be freed. After that, the first thread
would continue inside ath9k_tx99_init() and call
r = ath9k_tx99_send(sc, sc->tx99_skb, &txctl);
that would make use of the freed sc->tx99_skb memory.

The bug was triggered when do suspend/resuming continuously

4.12.0-041200rc4-generic. But can't reproduce on DELL

The warning is caused by accessing invalid pointer sc->rng_task.
sc->rng_task is not be cleared after kthread_stop(sc->rng_task)
be called in ath9k_rng_stop(). Because the kthread is stopped
before ath9k_rng_kthread() be scheduled.

So set sc->rng_task to null after kthread_stop(sc->rng_task) to
resolve this issue.

Subject: ath9k: avoid potential freezing during random generator read

In the worst case, ath9k_rng_stop() may take 10s to stop rng kthread.
The time is too long for users, use wait_event_interruptible_timeout()
instead of msleep_interruptible(), wakup immediately once
kthread_should_stop() is true.

Subject: mwifiex: Do not change bss_type in change_virtual_intf

When user adds a virtual interface driver will set the
bss_type to the iface_type given by the user. When
supplicant is started on the same interface, a call to
change_virtual_intf will be triggered if if_type is not
NL80211_IFTYPE_STATION. Here driver should not update
it's bss_type, because bss_type is intended to indicate
the original iface_type and changing the same will defeat
the purpose of creating this interface.

Since commit 9cc4b7cb86cb ("brcmfmac: Make skb header writable

driver was keeping statistics that got lost. So reworking the
code so we get those driver statistics back for debugging.

Subject: rsi: add in missing RSI_FSM_STATES into array fsm_state

Two recent commits added new RSI_FSM_STATES (namely FSM_FW_NOT_LOADED
and FSM_COMMON_DEV_PARAMS_SENT) and the corresponding table fsm_state
was not updated to match. This can lead to an array overrun when
accessing the latter two states in fsm_state. Fix this by adding in
the missing states.

Detected by CoverityScan, CID#1398379 ("Illegal address computation")

Fixes: 9920322ccd8e ("rsi: add tx frame for common device configuration")
Fixes: 015e367494c1 ("rsi: Register interrupt handler before firmware load")

Declare hwbus_ops structures as const as they are only passed as an
argument to the function cw1200_core_probe. This argument is of type
const. So, make these structures const.

We are going to add debugfs entry to retrieve the current geographic
profile being used in the FW. Currently the driver reads those tables
from the BIOS and passes them to the FW.
To prepare for this retrieving we want to store those
tables in the driver.

Subject: iwlwifi: dvm: use macros for format strings

Some static checkers (e.g. smatch) complain if a non-constant
format string is used, even if that's a static const variable.
Since there's no impact on code generation, just change those
format strings to be macros.

Subject: iwlwifi: pcie: fix 9000-series RF-kill interrupt propagation

A hardware issue on 9000 series devices sometimes causes RF-kill
interrupts to not be propagated to the host properly if ASPM is
enabled. Work around this by setting the right hardware bit to
allow it to interrupt the host for this reason (rfkill).

Subject: iwlwifi: mvm: simplify CHECK_MLME_TRIGGER macro

There's no reason to pass mvm and trig as parameters to the macro,
since it will be expanded inside the function itself.  Also remove the
bogus buf parameter which doesn't exist and is not used.

When the firmware supports CDB, PHY contexts cannot be modified to
change their band, but need to be added/remove instead. Instead of
relying on iwl_mvm_has_new_tx_api(), check the right FW capa flag
IWL_UCODE_TLV_CAPA_BINDING_CDB_SUPPORT and remove the comment.

Subject: iwlwifi: mvm: change when the BT_COEX is sent

The BT_COEX command should not be sent to the INIT
firmware image starting from 8000 family.
The firmware team also requested to send the BT_COEX
command after the PHY_DB_CMD and the PHY_CFG_CMD.

While at it:

Subject: iwlwifi: mvm: support multi tid ba notif

When receiving a BA_NOTIF on new TX API, it can
contain BAs for several TIDs. Go over them and
reclaim TX for every TID.

Note that although the small API change, the API
version still isn't bumped forward, as this NIC
isn't still officially released.

Subject: iwlwifi: unify external & internal modparam names

Where possible (all except for "11n_disable", which isn't valid in C)
rename the internal names for module parameters to be the same as the
externally visible names, to aid finding their use etc.

Subject: iwlwifi: pcie: warn if paging is already initialized during init

This appears to happen in some cases, like when iwlmvm is unloaded and
loaded again without also unloading iwlwifi. Warn in this case and free
the paging data to be able to continue without causing corruption and
kernel crashes due to it (otherwise, paging data is overwritten, but
dram->paging_cnt gets to be twice as big as it should be, and then an
eventual free will crash.)

Subject: iwlwifi: mvm: unconditionally stop device after init

In commit b93b1fe3b532 ("iwlwifi: mvm: fix init_dbg flow to work
as expected"), the code was changed to make the stop conditional
on not having failed (and on not having init_dbg), which doesn't
make sense - we should stop the device regardless of failures.

Failure to do so is leading to the device being enabled when it
shouldn't be, and - if it gets re-enabled later - the new context
info code gets confused as paging data wasn't freed.

Remove the invalid error condition again.

Subject: iwlwifi: mvm: fix deduplication start logic

If the first frame on a given TID is received with seqno 0 and needed
to be retransmitted, we erroneously drop it because the deduplication
data is initialized to zero, and then comparing

        if (unlikely(ieee80211_has_retry(hdr->frame_control) &&
                     dup_data->last_seq[tid] == hdr->seq_ctrl &&
                     dup_data->last_sub_frame[tid] >= sub_frame_idx))
                return true;

will return in iwl_mvm_is_dup() since last_sub_frame is also set to
zero, and sub_frame_idx is usually zero since this only covers the
relatively rare case of A-MSDU.

Fix this by initializing the last_seq array to 0xffff, which is an
impossible value for hdr->seq_ctrl to have here because the lower
four bits are the fragment number, and fragments aren't handled in
this code but go to mac80211 instead.

Subject: iwlwifi: create new subdirectory for FW interaction

There's a lot of mvm code that really should be more generic
and part of the iwlwifi module. Start by making a place to
keep such code - in the new "fw" subdirectory - and already
move the firmware related header files there.

Subject: iwlwifi: mvm: remove version 2 of paging command

Only a000-series devices were going to use this, but actually
initialize using the context info, which includes paging, so
this code is never invoked; remove it.

Subject: iwlwifi: mvm: quietly accept non-sta assoc response frames

When hostapd adds a station, it does so before sending the association
response frame, so that it can indicate the correct status code in the
response.

However, when this then fails, or the association response already is
a reject for some other reason, then there's no station entry and thus
no per-station management queue to send the response on and it must be
sent on the probe response queue. The code should therefore not warn.

In theory, we could check and warn if the status code is success, but
that seems excessive, so just relax the check to allow any association
response frames.

Subject: Bluetooth: hci_bcm: Add active_low irq polarity quirk for Asus
 T100CHI

Just like the T100TA the host-wake irq on the Asus T100CHI is
active low. Having a quirk for this is actually extra important on the
T100CHI as it ships with a bluetooth keyboard dock, which does not
work properly without this quirk.

The bond_options.c file contains multiple netdev_info statements that clutter kernel output.
This patch replaces all netdev_info with netdev_dbg and adds a netdev_dbg statement for the
packets per slave parameter. Also fixes misalignment at line 467.

Subject: net: stmmac: support future possible different internal phy mode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The current way to find if the phy is internal is to compare DT phy-mode
and emac_variant/internal_phy.
But it will negate a possible future SoC where an external PHY use the
same phy mode than the internal one.

By using phy-mode = "internal" we permit to have an external PHY with
the same mode than the internal one.

Subject: net: ethernet: ti: cpsw: fix sw timestamping for non PTP packets

The cpts can timestmap only ptp packets at this moment, so driver
cannot mark every packet as though it's going to be timestamped,
only because h/w timestamping for given skb is enabled with
SKBTX_HW_TSTAMP. It doesn't allow to use sw timestamping, as result
outgoing packet is not timestamped at all if it's not PTP and h/w
timestamping is enabled. So, fix it by setting SKBTX_IN_PROGRESS
only for PTP packets.

Subject: net: ethernet: ti: netcp_ethss: use cpts to check if packet needs
 timestamping

There is cpts function to check if packet can be timstamped with cpts.
Seems that ptp_classify_raw cover all cases listed with "case".

Subject: iwlwifi: mvm: properly enable IP header checksumming

The code was intended to enable IP header checksumming on AMSDUs, but
failed to really do so because the A-MSDU bit was set after all the
checksumming bits, and thus checking for A-MSDU could never be true.

Fix this by setting the A-MSDU bit before the offload bits.

Subject: iwlwifi: mvm: fix mac80211 queue tracking

In the driver, we track which hardware queue is associated with
which mac80211 "hw_queue", in order to be able to stop and wake
it. When moving these bitmaps out of the queue_info structures,
the type of the bitmap was erroneously changed from u32 to u8,
presumably in order to save memory.

Turns out that u32 isn't needed, because the highest queue we
can ever tell mac80211 is always < 16, but a u16 definitely is
needed, queues >=8 do happen.

While at it, throw a BUILD_BUG_ON() into the place where we set
the limit (mvm->first_agg_queue) and a warning when it actually
gets put into the bitmap.

The consequence of this bug is that full HW queues associated
with such a too-high mac80211 number never stop higher layer
queues when full, and thus would simply drop all packets that
couldn't be enqueued to the hardware queue.

There may be a difference between the mac80211 vif->cab_queue and
mvmvif->cab_queue, particularly with TVQM. Make the code map this
earlier, instead of first returning the mac80211 one again from
iwl_mvm_get_ctrl_vif_queue().

Subject: iwlwifi: mvm: fix mac80211's hw_queue in DQA mode

When in non-DQA mode, mac80211 actually gets a pretty much perfect
idea (in vif->hw_queue/cab_queue) of which queues we're using. But
in DQA mode, this isn't true - nonetheless, we were adding all the
queues, even the ones stations are using, to the queue allocation
bitmap.

Fix this, we should only add the queues we really are using in DQA
mode:
 * IWL_MVM_OFFCHANNEL_QUEUE, as we use this in both modes
 * mvm->aux_queue, as we use this in both modes - mac80211
   never really knows about it but we use it as a cookie
   internally, so can't reuse it
 * possibly the GCAST queue (cab_queue)
 * all the "queues" we told mac80211 about we were using on each
   interface (vif->hw_queue), these are entirely virtual in this
   mode

Also add back the failure now when we can't allocate any more of
these - now virtual - queues; this was skipped in DQA mode and
would lead to having multiple ACs or even interfaces use the same
queue number in mac80211 (10, since that's the limit), which would
stop far too many queues if stopped.

When going into suspend, the HW configuration for MSI-X will
likely be lost. As a consequence, after waking up, all IRQ
causes will be mapped to interrupt 0, and as a consequence we
don't notice the interrupt because in most cases this is an
interrupt for a queue, and getting it doesn't read the other
cause registers.

Subject: iwlwifi: mvm: remove DQA non-STA client mode special case

When we get a non-STA frame to transmit in client mode, we try to use
the IWL_MVM_DQA_BSS_CLIENT_QUEUE queue (queue #4). However, at this
point, the queue might not be allocated at all, causing warnings. The
scenario on which this happened was a race condition between mac80211
and our queue allocation work:
 * mac80211 sends auth
 * we stop mac80211 queues to allocate a hw queue
 * authentication is aborted
 * we allocate HW queue and start mac80211 queues
 * mac80211 removes station
 * mac80211 hands us the auth frame from the pending queue

At this point, since mac80211 has already removed the station, we try
to transmit the frame through this special non-station case on queue
4 anyway.

In order to really use it properly, we'd have to again go through the
hw queue allocation work, and attach it to a station, etc. In this
case that isn't possible (there's no station anymore), but if this
special case were needed, then we'd have to do it this way.

However, the special case is documented to exist for TDLS, but can't
trigger there because the TDLS setup frames etc. are normal to-DS
frames going to the peer through the AP. Testing also confirms that
this code path isn't triggered in TDLS.

Therefore, remove the code path to avoid using an unused queue. The
erroneous frame described above will still be transmitted on the AUX
queue, but arguably that's a mac80211 problem, which will eventually
be fixed by moving everything there to TXQs.

Subject: iwlwifi: mvm: quietly accept non-sta disassoc frames

When a station that's not associated sends a data frame (e.g. an NDP)
hostapd will respond with a disassoc frame, telling it that it's not
associated. The station might also not be authenticated, in which case
there will not be a station entry for it, and as a result we need to
accept such frames without a station.

Subject: iwlwifi: pcie: propagate iwl_pcie_apm_init's status

iwl_pcie_apm_init can fail so make sure that the caller
takes the status into account.
Also, ensure that the error that iwl_pcie_apm_init can emit
will appear in the kernel log by default.

Subject: iwlwifi: pcie: wait longer after device reset

The newest devices need a longer time to reset because of
their more complex hardware. Wait 5ms after device reset.
Consolidate all the places that reset the device in the
PCIe transport to avoid future bugs.

While at it, unify the flow to use set_bit instead of full
write as requested by the hardware designers.

Subject: amd-xgbe: Fix SFP PHY supported/advertised settings

When using SFPs, the supported and advertised settings should be initially
based on the SFP that has been detected.  The code currently indicates the
overall support of the device as opposed to what the SFP is capable of.
Update the code to change the supported link modes, auto-negotiation, etc.
to be based on the installed SFP.

Subject: amd-xgbe: Use the proper register during PTP initialization

During PTP initialization, the Timestamp Control register should be
cleared and not the Tx Configuration register.  While this typo causes
the wrong register to be cleared, the default value of each register and
and the fact that the Tx Configuration register is programmed afterwards
doesn't result in a bug, hence only fixing in net-next.

Subject: amd-xgbe: Add a check for an skb in the timestamp path

Spurious Tx timestamp interrupts can cause an oops in the Tx timestamp
processing function if a Tx timestamp skb is NULL. Add a check to insure
a Tx timestamp skb is present before attempting to use it.

Subject: amd-xgbe: Re-issue interrupt if interrupt status not cleared

Some of the device interrupts should function as level interrupts. For
some hardware configurations this requires setting some control bits
so that if the interrupt status has not been cleared the interrupt
should be reissued.

Additionally, when using MSI or MSI-X interrupts, run the interrupt
service routine as a tasklet so that the re-issuance of the interrupt
is handled properly.

Subject: amd-xgbe: Add NUMA affinity support for memory allocations

Add support to perform memory allocations on the node of the device. The
original allocation or the ring structure and Tx/Rx queues allocated all
of the memory at once and then carved it up for each channel and queue.
To best ensure that we get as much memory from the NUMA node as we can,
break the channel and ring allocations into individual allocations.

Subject: amd-xgbe: Simplify the burst length settings

Currently the driver hardcodes the PBLx8 setting.  Remove the need for
specifying the PBLx8 setting and automatically calculate based on the
specified PBL value. Since the PBLx8 setting applies to both Tx and Rx
use the same PBL value for both of them.

Also, the driver currently uses a bit field to set the AXI master burst
len setting. Change to the full bit field range and set the burst length
based on the specified value.

Subject: amd-xgbe: Adjust register settings to improve performance

Add support to change some general performance settings and to provide
some performance settings based on the device that is probed.

This includes:

- Setting the maximum read/write outstanding request limit
- Reducing the AXI interface burst length size
- Selectively setting the Tx and Rx descriptor pre-fetch threshold
- Selectively setting additional cache coherency controls

Tested and verified on all versions of the hardware.

Subject: arcnet: add err_skb package for package status feedback

We need to track the status of our queued packages. This way the driving
process knows if failed packages need to be retransmitted. For this
purpose we queue the transferred/failed packages back into the err_skb
message queue added with some status information.

Subject: ibmvnic: Fix assignment of RX/TX IRQ's

The driver currently creates RX/TX queues during device probe, but
assigns IRQ's to them during device open. On reset, however,
IRQ's are assigned when resetting the queues. If there is a reset
while the device is closed and the device is later opened, the driver will
request IRQ's twice, causing the open to fail. This patch assigns
the IRQ's in the ibmvnic_init function after the queues are reset or
initialized, ensuring IRQ's are only requested once.

Subject: net/mlx4_en: Add dynamic variable to hold the number of user
 priorities (UP)

Until this patch, the number of UPs was hard coded for eight.
Replace this with a variable in struct "mlx4_en_port_profile".
Currently, the variable will hold the maximum number of UP,
as before.
The patch creates an infrastructure to add an option for dynamic
change of the actual number of TCs.

Subject: net/mlx4_en: Do not allocate redundant TX queues when TC is disabled

Currently the number of TX queues that are allocated doesn't depend
on the number of TCs, the module always loads with max num of UP
per channel.
In order to prevent the allocation of unnecessary memory, the
module will load with minimum number of UPs per channel, and the
user will be able to control the number of TX queues per channel
by changing the number of TC to 8 using the tc command.
The variable num_up will hold the information about the current
number of UPs.
Due to the change, needed to remove the lines that set the value of
UP to be different than zero in the func "mlx4_en_select_queue",
since now the num of TX queues that are allocated is only one per channel
in default.
In order not to force the UP to be zero in case of only one TC, added
a condition before forcing it in the func "mlx4_en_fill_qp_context".

Tested:
After the module is loaded with minimum number of UP per channel, to
increase num of TCs to 8, use:
tc qdisc add dev ens8 root mqprio num_tc 8
In order to decrease the number of TCs to minimum number of UP per channel,
use:
tc qdisc del dev ens8 root

Subject: brcmfmac: support 4-way handshake offloading for WPA/WPA2-PSK

The firmware may have supplicant code built-in. This is detected
by the driver and indicated in the wiphy features flags. User-space
can use this flag to determine whether or not to provide the
pre-shared key material in the nl80211 CONNECT command.

Subject: brcmfmac: switch to using cfg80211_connect_done()

The driver used cfg80211_connect_result() which is basically a wrapper
around cfg80211_connect_done() passing a subset of the information that
can be passed. For upcoming functionality this is not sufficient so
switching to use cfg80211_connect_done().

Subject: mwifiex: do not update MCS set from hostapd

We should not copy the MCS set from hostapd RX-STBC. We
have to just use the MCS set supported by the hardware.
This fixes an issue, where mwifiex is advertising wrong
MCS sets in beacons.

Subject: net: macb: macb.c changed to macb_main.c

In case that macb is compiled as a module, macb.c has been renamed to
macb_main.c to avoid naming confusion in Makefile.

Subject: net: macb: Add hardware PTP support

This patch is based on original Harini's patch and Andrei's patch,
implemented in a separate file to ease the review/maintanance
and integration with other platforms.

This driver supports GEM-GXL:
- Register ptp clock framework
- Initialize PTP related registers
- HW time stamp on the PTP Ethernet packets are received using the
  SO_TIMESTAMPING API. Time stamps are obtained from the dma buffer
  descriptors
- add macb_ptp to compilation chain

From 633547973ffc32fd2c815639d4675e1531f0896f Mon Sep 17 00:00:00 2001
From: "Reshetova, Elena" <elena.reshetova@intel.com>
Date: Fri, 30 Jun 2017 13:07:58 +0300
Subject: net: convert sk_buff.users from atomic_t to refcount_t

refcount_t type and corresponding API should be
used instead of atomic_t when the variable is used as
a reference counter. This allows to avoid accidental
refcounter overflows that might lead to use-after-free
situations.

Subject: net: convert sock.sk_wmem_alloc from atomic_t to refcount_t

refcount_t type and corresponding API should be
used instead of atomic_t when the variable is used as
a reference counter. This allows to avoid accidental
refcounter overflows that might lead to use-after-free
situations.

Subject: nfp: add phys_switch_id support

Add phys_switch_id support by allowing lookup of
SWITCHDEV_ATTR_ID_PORT_PARENT_ID via the nfp_repr_port_attr_get
switchdev operation.

This is visible to user-space in the phys_switch_id attribute
of a netdev.

e.g.

cd /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0
find . -name phys_switch_id | xargs grep .
./net/eth3/phys_switch_id:00154d1300bd
./net/eth4/phys_switch_id:00154d1300bd
./net/eth2/phys_switch_id:00154d1300bd
grep: ./net/eth5/phys_switch_id: Operation not supported

In the above eth2 and eth3 and representor netdevs for the first and second
physical port. eth4 is the representor for the PF. And eth5 is the PF netdev.

Subject: nfp: provide infrastructure for offloading flower based TC filters

Adds a flower based TC offload handler for representor devices, this
is in addition to the bpf based offload handler. The changes in this
patch will be used in a follow-up patch to add tc flower offload to
the NFP.

The flower app enables tc offloads on representors by default.

Subject: nfp: add metadata to each flow offload

Adds metadata describing the mask id of each flow and keeps track of
flows installed in hardware. Previously a flow could not be removed
from hardware as there was no way of knowing if that a specific flow
was installed. This is solved by storing the offloaded flows in a
hash table.

From abfcdc1de9bf38cdde6792a165c75d9037ea35fe Mon Sep 17 00:00:00 2001

Subject: nfp: add a stats handler for flower offloads

Previously there was no way of updating flow rule stats after they
have been offloaded to hardware. This is solved by keeping track of
stats received from hardware and providing this to the TC handler
on request.

Subject: nfp: add control message passing capabilities to flower offloads

Previously the flower offloads never sends messages to the hardware,
and never registers a handler for receiving messages from hardware.
This patch enables the flower offloads to send control messages to
hardware when adding and removing flow rules. Additionally it
registers a control message rx handler for receiving stats updates
from hardware for each offloaded flow.

Additionally this patch adds 4 control message types; Add, modify and
delete flow, as well as flow stats. It also allows
nfp_flower_cmsg_get_data() to be used outside of cmsg.c.

From 67b40dccc45ff5d488aad17114e80e00029fd854 Mon Sep 17 00:00:00 2001
From: "Kalderon, Michal" <Michal.Kalderon@cavium.com>

Subject: qed: Implement iWARP initialization, teardown and qp operations

This patch adds iWARP support for flows that have common code
between RoCE and iWARP, such as initialization, teardown and
qp setup verbs: create, destroy, modify, query.
It introduces the iWARP specific files qed_iwarp.[ch] and
iwarp_common.h

Subject: qed: iWARP CM - setup a ll2 connection for handling SYN packets

iWARP handles incoming SYN packets using the ll2 interface. This patch
implements ll2 setup and teardown. Additional ll2 connections will
be used in the future which are not part of this patch series.

From 65a91a6cdb868a28b919ca133c0f9d9dfd9a635a Mon Sep 17 00:00:00 2001
From: "Kalderon, Michal" <Michal.Kalderon@cavium.com>
Date: Sun, 2 Jul 2017 10:29:26 +0300
Subject: qed: iWARP CM add listener functions and initial SYN processing

This patch adds the ability to add and remove listeners and identify
whether the SYN packet received is intended for iWARP or not. If
a listener is not found the SYN packet is posted back to the chip.

Subject: qed: iWARP CM add passive side connect

This patch implements the passive side connect.
It addresses pre-allocating resources, creating a connection
element upon valid SYN packet received. Calling upper layer and
implementation of the accept/reject calls.

Error handling is not part of this patch.

From: "Kalderon, Michal" <Michal.Kalderon@cavium.com>
Date: Sun, 2 Jul 2017 10:29:28 +0300
Subject: qed: iWARP CM add active side connect

This patch implements the active side connect.
Offload a connection, process MPA reply and send RTR.
In some of the common passive/active functions, the active side
will work in blocking mode.

Subject: qed: iWARP implement disconnect flows

This patch takes care of active/passive disconnect flows.
Disconnect flows can be initiated remotely, in which case a async event
will arrive from peer and indicated to qedr driver. These
are referred to as exceptions. When a QP is destroyed, it needs to check
that it's associated ep has been closed.

Subject: net: cdc_ncm: Reduce memory use when kernel memory low
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The CDC-NCM driver can require large amounts of memory to create
skb's and this can be a problem when the memory becomes fragmented.

This especially affects embedded systems that have constrained
resources but wish to maximise the throughput of CDC-NCM with 16KiB
NTB's.

The issue is after running for a while the kernel memory can become
fragmented and it needs compacting.
If the NTB allocation is needed before the memory has been compacted
the atomic allocation can fail which can cause increased latency,
large re-transmissions or disconnections depending upon the data
being transmitted at the time.
This situation occurs for less than a second until the kernel has
compacted the memory but the failed devices can take a lot longer to
recover from the failed TX packets.

To ease this temporary situation I modified the CDC-NCM TX path to
temporarily switch into a reduced memory mode which allocates an NTB
that will fit into a USB_CDC_NCM_NTB_MIN_OUT_SIZE (default 2048 Bytes)
sized memory block and only transmit NTB's with a single network frame
until the memory situation is resolved.
Each time this issue occurs we wait for an increasing number of
reduced size allocations before requesting a full size one to not
put additional pressure on a low memory system.

Once the memory is compacted the CDC-NCM data can resume transmitting
at the normal tx_max rate once again.

Subject: vxlan: correctly set vxlan->net when creating the device in a netns

Commit a985343ba906 ("vxlan: refactor verification and application of
configuration") modified vxlan device creation, and replaced the
assignment of vxlan->net to src_net with dev_net(netdev) in ->setup().

But dev_net(netdev) is not the same as src_net. At the time ->setup()
is called, dev_net hasn't been set yet, so we end up creating the
socket for the vxlan device in init_net.

Fix this by bringing back the assignment of vxlan->net during device
creation.

Pointer hdr in netxen_setup_minidump() is set but never used, thus
should be removed.

refcount_t type and corresponding API should be
used instead of atomic_t when the variable is used as
a reference counter. This allows to avoid accidental
refcounter overflows that might lead to use-after-free
situations.

Subject: nfp: improve order of interfaces in breakout mode

For historical reasons we enumerate the vNICs in order.  This means
that if user configures breakout on a multiport card, the first
interface of the second port will have its MAC address changed.

What's worse, when moved from static information (HWInfo) to using
management FW (NSP), more features started depending on the port ids.
Right now in case of breakout first subport of the second port and
second subport of the first port will have their link info swapped.

Revise the ordering scheme so that first subport maintains its address.
Side effect of this change is that we will use base lane ids in
devlink (i.e. 40G ports will be 4 ids apart), e.g.:

pci/0000:04:00.0/0: type eth netdev p6p1
pci/0000:04:00.0/4: type eth netdev p6p2

Note that behaviour of phys_port_id is not changed since there is
a separate id number for the subport there.

Subject: nfp: remove legacy MAC address lookup

The legacy MAC address lookup doesn't work well with breakout
cables.  We are probably better off picking random addresses
than the wrong ones in the theoretical scenario where management
FW didn't tell us what the port config is.

Subject: nfp: default to chained metadata prepend format

ABI 4.x introduced the chained metadata format and made it the
only one possible.  There are cases, however, where the old
format is preferred - mostly to make interoperation with VFs
using ABI 3.x easier for the datapath.  In ABI 5.x we allowed
for more flexibility by selecting the metadata format based
on capabilities.  The default was left to non-chained.

In case of fallback traffic, there is no capability telling the
driver there may be chained metadata.  With a very stripped-
-down FW the default old metadata format would be selected
making the driver drop all fallback traffic.

This patch changes the default selection in the driver. It
should not hurt with old firmwares, because if they don't
advertise RSS they will not produce metadata anyway.  New
firmwares advertising ABI 5.x, however, can depend on the
driver defaulting to chained format.

Fixes: f9380629fafc ("nfp: advertise support for NFD ABI 0.5")

Subject: net: phy: dp83867: add workaround for incorrect RX_CTRL pin strap

The data manual for DP83867IR/CR, SNLS484E[1], revised march 2017,
advises that strapping RX_DV/RX_CTRL pin in mode 1 and 2 is not
supported (see note below Table 5 (4-Level Strap Pins)).

There are some boards which have the pin strapped this way and need
software workaround suggested by the data manual. Bit[7] of
Configuration Register 4 (address 0x0031) must be cleared to 0. This
ensures proper operation of the PHY.

Implement driver support for device-tree property meant to advertise
the wrong strapping.
