mlxsw_sp_nexthop_counter_disable() decays to a nop when called on a
disabled counter, but mlxsw_sp_nexthop_counter_enable() can't similarly
be called on an enabled counter. This would be useful in the following
patches. Add the missing condition.

For the report_delta-like interface like a previous patch has added for
collection of NH group statistics, it's easiest to read the counter and
have the HW clear it right away. Thus, change mlxsw_sp_flow_counter_get()
to take a bool indicating whether this should be done.

The function mlxsw_sp_nexthop_counter_alloc() doesn't directly allocate
anything, and mlxsw_sp_nexthop_counter_free() doesn't directly free. For
the following patches, we will need names for functions that actually do
those things. Therefore rename to mlxsw_sp_nexthop_counter_enable() and
mlxsw_sp_nexthop_counter_disable() to free up the namespace.

Add a space (' ') prefix to every userdata line to match docs for
dev-kmsg. To account for this extra character in each userdata entry,
reduce userdata entry names (directory name) from 54 characters to 53.
According to the dev-kmsg docs, a space is used for subsequent lines to
mark them as continuation lines.
> A line starting with ' ', is a continuation line, adding
> key/value pairs to the log message, which provide the machine
> readable context of the message, for reliable processing in
> userspace.
Testing for this patch::
cd /sys/kernel/config/netconsole && mkdir cmdline0
cd cmdline0
mkdir userdata/test && echo "hello" > userdata/test/value
mkdir userdata/test2 && echo "hello2" > userdata/test2/value
echo "message" > /dev/kmsg
Outputs::
6.8.0-rc5-virtme,12,493,231373579,-;message
test=hello
test2=hello2
And I confirmed all testing works as expected from the original patchset

Handling case err == 0 in the other branch allows to simplify the

Disable LEDs just before resetting the MT7530 to avoid
situations where the ESW_P4_LED_0 and ESW_P3_LED_0 pin
states may cause an unintended external crystal frequency
to be selected.
The HT_XTAL_FSEL (External Crystal Frequency Selection)
field of HWTRAP (the Hardware Trap register) stores a
2-bit value that represents the state of the ESW_P4_LED_0
and ESW_P4_LED_0 pins (seemingly) sampled just after the
MT7530 has been reset, as:
ESW_P4_LED_0 ESW_P3_LED_0 Frequency
-----------------------------------------
0 1 20MHz
1 0 40MHz
1 1 25MHz
The value of HT_XTAL_FSEL is bootstrapped by pulling
ESW_P4_LED_0 and ESW_P3_LED_0 up or down accordingly,
but:
if a 40MHz crystal has been selected and
the ESW_P3_LED_0 pin is high during reset,
or a 20MHz crystal has been selected and
the ESW_P4_LED_0 pin is high during reset,
then the value of HT_XTAL_FSEL will indicate
that a 25MHz crystal is present.
By default, the state of the LED pins is PHY controlled
to reflect the link state.
To illustrate, if a board has:
5 ports with active low LED control,
and HT_XTAL_FSEL bootstrapped for 40MHz.
When the MT7530 is powered up without any external
connection, only the LED associated with Port 3 is
illuminated as ESW_P3_LED_0 is low.
In this state, directly after mt7530_setup()'s reset
is performed, the HWTRAP register (0x7800) reflects
the intended HT_XTAL_FSEL (HWTRAP bits 10:9) of 40MHz:
mt7530-mdio mdio-bus:1f: mt7530_read: 00007800 == 00007dcf
>>> bin(0x7dcf >> 9 & 0b11)
'0b10'
But if a cable is connected to Port 3 and the link
is active before mt7530_setup()'s reset takes place,
then HT_XTAL_FSEL seems to be set for 25MHz:
mt7530-mdio mdio-bus:1f: mt7530_read: 00007800 == 00007fcf
>>> bin(0x7fcf >> 9 & 0b11)
'0b11'
Once HT_XTAL_FSEL reflects 25MHz, none of the ports
are functional until the MT7621 (or MT7530 itself)
is reset.
By disabling the LED pins just before reset, the chance
of an unintended HT_XTAL_FSEL value is reduced.

ethtool: ice: Support for RSS settings to GTP
Takeru Hayasaka enables RSS functionality for GTP packets on ice driver
with ethtool.
A user can include TEID and make RSS work for GTP-U over IPv4 by doing the
following:`ethtool -N ens3 rx-flow-hash gtpu4 sde`
In addition to gtpu(4|6), we now support gtpc(4|6),gtpc(4|6)t,gtpu(4|6)e,
gtpu(4|6)u, and gtpu(4|6)d.
gtpc(4|6): Used for GTP-C in IPv4 and IPv6, where the GTP header format does
not include a TEID.
gtpc(4|6)t: Used for GTP-C in IPv4 and IPv6, with a GTP header format that
includes a TEID.
gtpu(4|6): Used for GTP-U in both IPv4 and IPv6 scenarios.
gtpu(4|6)e: Used for GTP-U with extended headers in both IPv4 and IPv6.
gtpu(4|6)u: Used when the PSC (PDU session container) in the GTP-U extended
header includes Uplink, applicable to both IPv4 and IPv6.
gtpu(4|6)d: Used when the PSC in the GTP-U extended header includes Downlink,
for both IPv4 and IPv6.

Following the addition of new GTP RSS hash options to ethtool.h, this patch
implements the corresponding RSS settings for GTP packets in the Intel ice
driver. It enables users to configure RSS for GTP-U and GTP-C traffic over IPv4
and IPv6, utilizing the newly defined hash options.
The implementation covers the handling of gtpu(4|6), gtpc(4|6), gtpc(4|6)t,
gtpu(4|6)e, gtpu(4|6)u, and gtpu(4|6)d traffic, providing enhanced load
distribution for GTP traffic across multiple processing units.

Support Multi-PF netdev (Socket Direct)
This series adds support for combining multiple devices (PFs) of the
same port under one netdev instance. Passing traffic through different
devices belonging to different NUMA sockets saves cross-numa traffic and
allows apps running on the same netdev from different numas to still
feel a sense of proximity to the device and achieve improved
performance.
We achieve this by grouping PFs together, and creating the netdev only
once all group members are probed. Symmetrically, we destroy the netdev
once any of the PFs is removed.
The channels are distributed between all devices, a proper configuration
would utilize the correct close numa when working on a certain app/cpu.
We pick one device to be a primary (leader), and it fills a special
role. The other devices (secondaries) are disconnected from the network
in the chip level (set to silent mode). All RX/TX traffic is steered
through the primary to/from the secondaries.
Currently, we limit the support to PFs only, and up to two devices
(sockets).

1) Each TX TLS device offloaded context has its own TIS object. Extra work
is needed to get it working in a SD environment, where a stream can move
between different SQs (belonging to different mdevs).
2) Each RX TLS device offloaded context needs a DEK object from the DEK
pool.
Extra work is needed to get it working in a SD environment, as the DEK
pool currently falsely depends on TX cap, and is on the primary device
only.
Disallow this combination for now.

Distribute the channels between the different SD-devices to acheive
local numa node performance on multiple numas.
Each channel works against one specific mdev, creating all datapath
queues against it.
We distribute channels to mdevs in a round-robin policy.
Example for 2 mdevs and 6 channels:
+-------+---------+
| ch ix | mdev ix |
+-------+---------+
| 0 | 0 |
| 1 | 1 |
| 2 | 0 |
| 3 | 1 |
| 4 | 0 |
| 5 | 1 |
+-------+---------+
This round-robin distribution policy is preferred over another suggested
intuitive distribution, in which we first distribute one half of the
channels to mdev #0 and then the second half to mdev #1.
We prefer round-robin for a reason: it is less influenced by changes in
the number of channels. The mapping between channel index and mdev is
fixed, no matter how many channels the user configures. As the channel
stats are persistent to channels closure, changing the mapping every
single time would turn the accumulative stats less representing of the
channel's history.
Per-channel objects should stop using the primary mdev (priv->mdev)
directly, and instead move to using their own channel's mdev.

Implement the needed SD steering adjustments for the primary and
secondaries.
While the SD multiple PFs are used to avoid cross-numa memory, when it
comes to chip level all traffic goes only through the primary device.
The secondaries are forced to silent mode, to guarantee they are not
involved in any unexpected ingress/egress traffic.
In RX, secondary devices will not have steering objects. Traffic will be
steered from the primary device to the RQs of a secondary device using
advanced cross-vhca RX steering capabilities.
In TX, the primary creates a new TX flow table, which is aliased by the
secondaries.

Use devcom to communicate between the different devices. Add a new
devcom component type for this.
Each device registers itself to the devcom component <SD, group ID>.
Once all devices of a component are registered, the component becomes
ready, and a primary device is elected.
In principle, any of the devices can act as a primary, they are all
capable, and a random election would've worked. However, we aim to
achieve predictability and consistency, hence each group always choses
the same device, with the lowest PCI BUS number, as primary.

====================
pull-request: ieee802154-next 2024-03-07
Various cross tree patches for ieee802154v drivers and a resource leak
fix for ieee802154 llsec.
Andy Shevchenko changed GPIO header usage for at86rf230 and mcr20a to
only include needed headers.
Bo Liu converted the at86rf230, mcr20a and mrf24j40 driver regmap
support to use the maple tree register cache.
Fedor Pchelkin fixed a resource leak in the llsec key deletion path.
Ricardo B. Marliere made wpan_phy_class const.
Tejun Heo removed WQ_UNBOUND from a workqueue call in ca8210.

Workqueue is in the process of cleaning up the distinction between unbound
workqueues w/ @nr_active==1 and ordered workqueues. Explicit WQ_UNBOUND
isn't needed for alloc_ordered_workqueue() and will trigger a warning in the
future. Let's remove it. This doesn't cause any functional changes.

Unlike the event configuration which can be modified by MHI, the
channel and controller configurations are expected to be const. And
since they are not modified locally, constify them to prevent runtime
modification.
No functional changes, compile tested only.

Currently buf_len field of ath11k_mhi_config_qca6390 is assigned
with 0, making MHI use a default size, 64KB, to allocate channel
buffers. This is likely to fail in some scenarios where system
memory is highly fragmented and memory compaction or reclaim is
not allowed.
There is a fail report which is caused by it:

Actually those buffers are used only by QMI target -> host communication.
And for WCN6855 and QCA6390, the largest packet size for that is less
than 6KB. So change buf_len field to 8KB, which results in order 1
allocation if page size is 4KB. In this way, we can at least save some
memory, and as well as decrease the possibility of allocation failure
in those scenarios.

Every time the firmware boots we call ath11k_core_qmi_firmware_ready() which
ends up calling ath11k_thermal_register(). So we try to register thermal
devices multiple times. And when we power off the firmware during
suspend/hibernation (implemented in the next patch) we get a warning in resume:
hwmon hwmon4: PM: parent phy0 should not be sleeping
Workaround this similarly like ath11k_mac_register() does by testing
ATH11K_FLAG_REGISTERED.

Both the firmware reset feature and the power management
suspend/resume feature share common power-down and power-up
functionality. One aspect of the power-up functionality is
the handling of the ATH11K_QMI_EVENT_FW_INIT_DONE event.
When this event is received, a call is made to
ath11k_hal_dump_srng_stats(), with the purpose to collect
information that may be useful in debugging the cause of a
firmware reset.
Unfortunately, since this functionality is shared between
both the firmware reset path and the power management
resume path, the kernel log is flooded with messages during
resume. Since these messages are not useful during resume,
and in fact can be confusing and can increase the time it
takes to resume, update the logic to only call
ath11k_hal_dump_srng_stats() during firmware reset.

There is no driver to match these two channels, so
remove them. This fixes warnings from MHI subsystem during suspend:
mhi mhi0_LOOPBACK: 1: Failed to reset channel, still resetting
mhi mhi0_LOOPBACK: 0: Failed to reset channel, still resetting

For non WoW suspend/resume, ath11k host powers down whole hardware
when suspend and powers up it when resume, the code path it goes
through is very like the ath11k reset logic.
In order to reuse that logic, rearrange IRQ handling in the reset
path.

Now WoWLAN firmware will disable PCIE DMA after driver call cfg_wake
function, and it will lead to release offload packet fail because driver
can't receive completion notification from firmware. We move release
offload packet earlier to avoid this error.

The security engine is set for management frames by default for 802.11be
chips, so no need to set it in WoWLAN flow.

The setting during suspend or resume is different between different
generation, so update it.
