[ Upstream commit d22fcc806b84b9818de08b32e494f3c05dd236c7 ]
Before this patch, when adding multiple ethtool steering rules with
identical classification, the driver used to append the new destination
to the already existing hw rule, which caused the hw to forward the
traffic to all destinations (rx queues).
Here we avoid this by setting the "no append" mlx5 fs core flag when
adding a new ethtool rule.

[ Upstream commit 276d197e70bcc47153592f4384675b51c7d83aba ]
CQE recovery function begins with test and set of recovery bit. Add an
error flow which ensures clearing of this bit when leaving the recovery
function, to allow further recoveries to take place. This allows removal

[ Upstream commit 405b93eb764367a670e729da18e54dc42db32620 ]
The current ARFS code relies on certain fields to be set in the SKB
(e.g. transport_header) and extracts IP addresses and ports by custom
code that parses the packet. The necessary SKB fields, however, are not
always set at that point, which leads to an out-of-bounds access. Use
skb_flow_dissect_flow_keys() to get the necessary information reliably,
fix the out-of-bounds access and reuse the code.

[ Upstream commit d9a2fcf53c76a7edb2bcf99e94507935561a83d5 ]
Remove wrong error return value when SQ is not in error state.
CQE recovery on TX reporter queries the sq state. If the sq is not in
error state, the sq is either in ready or reset state. Ready state is
good state which doesn't require recovery and reset state is a temporal
state which ends in ready state. With this patch, CQE recovery in this
scenario is successful.

[ Upstream commit 4b95840a6ced0634082f6d962ba9aa0ce797f12f ]
Speed translation is performed based on legacy or extended PTYS
register. Translate speed with respect to:
1) Capability bit of extended PTYS table.
2) User request:
a) When auto-negotiation is turned on, inspect advertisement whether it
contains extended link modes.
b) When auto-negotiation is turned off, speed > 100Gbps (maximal
speed supported in legacy mode).
With both conditions fulfilled translation is done with extended PTYS
table otherwise use legacy PTYS table.
Without this patch 25/50/100 Gbps speed cannot be set, since try to
configure in extended mode but read from legacy mode.

[ Upstream commit 90bb769291161cf25a818d69cf608c181654473e ]
This patch prevents a race between user invoked cached counters
query and a neighbor last usage updater.
The cached flow counter stats can be queried by calling
"mlx5_fc_query_cached" which provides the number of bytes and
packets that passed via this flow since the last time this counter
was queried.
It does so by reducting the last saved stats from the current, cached
stats and then updating the last saved stats with the cached stats.
It also provide the lastuse value for that flow.
Since "mlx5e_tc_update_neigh_used_value" needs to retrieve the
last usage time of encapsulation flows, it calls the flow counter
query method periodically and async to user queries of the flow counter
using cls_flower.
This call is causing the driver to update the last reported bytes and
packets from the cache and therefore, future user queries of the flow
stats will return lower than expected number for bytes and packets
since the last saved stats in the driver was updated async to the last
saved stats in cls_flower.
This causes wrong stats presentation of encapsulation flows to user.
Since the neighbor usage updater only needs the lastuse stats from the
cached counter, the fix is to use a dedicated lastuse query call that
returns the lastuse value without synching between the cached stats and
the last saved stats.

[ Upstream commit 60d60c8fbd8d1acf25b041ecd72ae4fa16e9405b ]
The commit 069d11465a80 ("net/mlx5e: RX, Enhance legacy Receive Queue
memory scheme") introduced an undefined behaviour below due to
"frag->last_in_page" is only initialized in mlx5e_init_frags_partition()

or after bailed out the loop,
for (i = 0; i < mlx5_wq_cyc_get_size(&rq->wqe.wq); i++)
As the result, there could be some "frag" have uninitialized
value of "last_in_page".
Later, get_frag() obtains those "frag" and check "frag->last_in_page" in
mlx5e_put_rx_frag() and triggers the error during boot. Fix it by always
initializing "frag->last_in_page" to "false" in
mlx5e_init_frags_partition().

[ Upstream commit 577fa14d210073ba1ce6237c659a8820312104ad ]
The switch periodically sends notifications about learned FDB entries.
Among other things, the notification includes the FID (Filtering
Identifier) and the port on which the MAC was learned.
In case the driver does not have the FID defined on the relevant port,
the following error will be periodically generated:
mlxsw_spectrum2 0000:06:00.0 swp32: Failed to find a matching {Port, VID} following FDB notification
This is not supposed to happen under normal conditions, but can happen
if an ingress tc filter with a redirect action is installed on a bridged
port. The redirect action will cause the packet's FID to be changed to
the dummy FID and a learning notification will be emitted with this FID
- which is not defined on the bridged port.
Fix this by having the driver ignore learning notifications generated
with the dummy FID and delete them from the device.
Another option is to chain an ignore action after the redirect action
which will cause the device to disable learning, but this means that we
need to consume another action whenever a redirect action is used. In
addition, the scenario described above is merely a corner case.

[ Upstream commit dedfde2fe1c4ccf27179fcb234e2112d065c39bb ]
Spectrum systems use DSCP rewrite map to update DSCP field in egressing
packets to correspond to priority that the packet has. Whether rewriting
will take place is determined at the point when the packet ingresses the
switch: if the port is in Trust L3 mode, packet priority is determined from
the DSCP map at the port, and DSCP rewrite will happen. If the port is in
Trust L2 mode, 802.1p is used for packet prioritization, and no DSCP
rewrite will happen.
The driver determines the port trust mode based on whether any DSCP
prioritization rules are in effect at given port. If there are any, trust
level is L3, otherwise it's L2. When the last DSCP rule is removed, the
port is switched to trust L2. Under that scenario, if DSCP of a packet
should be rewritten, it should be rewritten to 0.
However, when switching to Trust L2, the driver neglects to also update the
DSCP rewrite map. The last DSCP rule thus remains in effect, and packets
egressing through this port, if they have the right priority, will have
their DSCP set according to this rule.
Fix by first configuring the rewrite map, and only then switching to trust
L2 and bailing out.

[ Upstream commit e18953240de8b46360a67090c87ee1ef8160b35d ]
When an XDP program is set, a full reopen of all channels happens in two
cases:
1. When there was no program set, and a new one is being set.
2. When there was a program set, but it's being unset.
The full reopen is necessary, because the channel parameters may change
if XDP is enabled or disabled. However, it's performed in an unsafe way:
if the new channels fail to open, the old ones are already closed, and
the interface goes down. Use the safe way to switch channels instead.
The same way is already used for other configuration changes.

Due to an issue on Spectrum-2, in front-panel ports split four ways, 2 out
of 32 port buffers cannot be used. To work around this, the next FW release
will mark them as unused, and will report correspondingly lower total
shared buffer size. mlxsw will pick up the new value through a query to
cap_total_buffer_size resource. However the initial size for shared buffer
pool 0 is hard-coded and therefore needs to be updated.
Thus reduce the pool size by 2.7 MiB (which corresponds to 2/32 of the
total size of 42 MiB), and round down to the whole number of cells.

The driver tries to periodically refresh neighbours that are used to
reach nexthops. This is done by periodically calling neigh_event_send().
However, if the neighbour becomes dead, there is nothing we can do to
return it to a connected state and the above function call is basically
a NOP.
This results in the nexthop never being written to the device's
adjacency table and therefore never used to forward packets.
Fix this by dropping our reference from the dead neighbour and
associating the nexthop with a new neigbhour which we will try to
refresh.

The same hash function and seed are used for both ECMP and LAG hash.

After introducing dedicated uplink representor, the netdev instance
set over the esw manager vport (PF) became no longer in use, so it was
removed in the cited commit once we're on switchdev mode.
However, the mlx5e_detach function was not updated accordingly, and it
still tries to detach a non-existing netdev, causing a kernel crash.
This patch fixes this issue.

The TX queue index returned by the fallback function ranges
between [0,NUM CHANNELS - 1] if QoS isn't set and
[0, (NUM CHANNELS)*(NUM TCs) -1] otherwise.
Our HW uses different TC mapping than the fallback function
(which is denoted as 'up', user priority) so we only need to extract
a channel number out of the returned value.
Since (NUM CHANNELS)*(NUM TCs) is a relatively small number, using
reciprocal scale almost always returns zero.
We instead access the 'txq2sq' table to extract the sq (and with it the
channel number) associated with the tx queue, thus getting
a more evenly distributed channel number.
Perf:
Rx/Tx side with Intel(R) Xeon(R) Silver 4108 CPU @ 1.80GHz and ConnectX-5.
Used 'iperf' UDP traffic, 10 threads, and priority 5.
Before: 0.566Mpps
After: 2.37Mpps
As expected, releasing the existing bottleneck of steering all traffic
to TX queue zero significantly improves transmission rates.

Prior to reloading a device we must first verify that it was not already
removed. Otherwise, the attempt to remove the device will do nothing, and
in that case we will end up proceeding with adding an new device that no
one was expecting to remove, leaving behind used resources such as EQs that
causes a failure to destroy comp EQs and syndrome (0x30f433).
Fix that by making sure that we try to remove and add a device (based on a

When CQE compression is enabled (Multi-host systems), compressed CQEs
might arrive to the driver rx, compressed CQEs don't have a valid hash
offload and the driver already reports a hash value of 0 and invalid hash
type on the skb for compressed CQEs, but this is not good enough.
On a congested PCIe, where CQE compression will kick in aggressively,
gro will deliver lots of out of order packets due to the invalid hash
and this might cause a serious performance drop.
The only valid solution, is to disable rxhash offload at all when CQE
compression is favorable (Multi-host systems).

Pull SPDX update from Greg KH:
"Here is a series of patches that add SPDX tags to different kernel
files, based on two different things:
- SPDX entries are added to a bunch of files that we missed a year
ago that do not have any license information at all.
These were either missed because the tool saw the MODULE_LICENSE()
tag, or some EXPORT_SYMBOL tags, and got confused and thought the
file had a real license, or the files have been added since the
last big sweep, or they were Makefile/Kconfig files, which we
didn't touch last time.
- Add GPL-2.0-only or GPL-2.0-or-later tags to files where our scan
tools can determine the license text in the file itself. Where this
happens, the license text is removed, in order to cut down on the
700+ different ways we have in the kernel today, in a quest to get
rid of all of these.
These patches have been out for review on the linux-spdx@vger mailing
list, and while they were created by automatic tools, they were
hand-verified by a bunch of different people, all whom names are on
the patches are reviewers.
The reason for these "large" patches is if we were to continue to
progress at the current rate of change in the kernel, adding license
tags to individual files in different subsystems, we would be finished
in about 10 years at the earliest.
There will be more series of these types of patches coming over the
next few weeks as the tools and reviewers crunch through the more
"odd" variants of how to say "GPLv2" that developers have come up with
over the years, combined with other fun oddities (GPL + a BSD
disclaimer?) that are being unearthed, with the goal for the whole
kernel to be cleaned up.
These diffstats are not small, 3840 files are touched, over 10k lines
removed in just 24 patches"
