They're unused since the original 2010

iwl_ppag_table_cmd versions"
It turns out that version 6 is still needed.
This change will be brought back once the FW that supports version 6 will no
longer be supported.
This reverts commit 24bc49d158c7 ("wifi: iwlwifi: remove support of several

This feature turns out to have an issue: it can take up to 8 seconds to
detect high throughput scenarios and to leave RX OMI bandwidth
reduction. This leads to throughput degradation.

This version doesn't provide the sta id, so we need to look it up -
assuming that no other sta exists, since one of the conditions of
entering OMI is not having P2P/TDLS.
But when we leave OMI, because of the P2P/TDLS activation, the P2P/TDLS
sta can already exist while we receive the notification from the FW.
This causes an error log which is incorrect.
Since OMI is only supported in SC, which is not shipped yet, no one will
use a FW with the old version.
Remove support for it.

The only difference between SC2 and SC2F is that they use a different
FSEQ image.
The firmware of SC2 implements the logic of selecting the right FSEQ
image to load, so there is no need for SC2F firmware image.

If no frames are received on a queue for a while, the reorder buffer
head_sn may be an old one. When the next frame that is received on
that queue and buffered is a subframe of an AMSDU but not the last
subframe, it will not update the buffer's head_sn. When the frame
release notification arrives, it will not release the buffered frame
because it will look like the notification's NSSN is lower than the
buffer's head_sn (because of a wraparound).
Fix it by updating the head_sn when the first frame is buffered.

When fips_enabled is set, keys will not be given to the
hardware by mac80211 since the hardware isn't certified.
In this case, various features cannot work correctly as
the firmware needs to handle frames, but it then cannot
since no keys are available.
Disable features:
- WoWLAN since no keys etc.
- MFP since some frames need to be handled in firmware
- EHT/6GHz since MFP is required
Also restrict A-MSDU size since A-MSDUs cannot be split
up by hardware and thus need to fit into the RX buffers
in one piece.

This driver was written with multiple SOC platforms in mind. However
since Ralink was aquired by Mediatek, it only effectively got used by
older platforms. As such, we can slim down the driver slightly by moving
all of rt2x00soc to rt2800soc in order to benefit from inlining.

The test is supposed to observe that the 'clash_resolve' stat counter
incremented (i.e., the code path was covered).
This check was incorrect, 'conntrack -S' needs to be called in the
revevant namespace, not the initial netns.
The clash resolution logic in conntrack is only exercised when multiple
packets with the same udp quadruple race. Depending on kernel config,
number of CPUs, scheduling policy etc. this might not trigger even
after several retries. Thus the script eventually returns SKIP if the
retry count is exceeded.
The udpclash tool with also exit with a failure if it did not observe
the expected number of replies.
In the script, make a note of this but do not fail anymore, just check if
the clash resolution logic triggered after all.
Remove the 'single-core' test: while unlikely, with preemptible kernel it
should be possible to also trigger clash resolution logic.
With this change the test will either SKIP or pass.
Hard error could be restored later once its clear whats going on, so
also dump 'conntrack -S' when some packets went missing to see if
conntrack dropped them on insert.

The nipa CI is reporting frequent failures in the mptcp_connect
self-tests.
In the failing scenarios (TCP -> MPTCP) the involved sockets are
actually plain TCP ones, as fallback for passive socket at 2whs
time cause the MPTCP listener to actually create a TCP socket.
The transfer is stuck due to the receiver buffer being zero.
With the stronger check in place, tcp_clamp_window() can be invoked
while the TCP socket has sk_rmem_alloc == 0, and the receive buffer
will be zeroed, too.
Check for the critical condition in tcp_prune_queue() and just
drop the packet without shrinking the receiver buffer.

Background
==========
When TCP retransmits a packet due to missing ACKs, the
retransmission may fail for various reasons (e.g., packets
stuck in driver queues, receiver zero windows, or routing issues).
The original tcp_retransmit_skb tracepoint:
'commit e086101b150a ("tcp: add a tracepoint for tcp retransmission")'
lacks visibility into these failure causes, making production
diagnostics difficult.
Solution
========
Adds the retval("err") to the tcp_retransmit_skb tracepoint.
Enables users to know why some tcp retransmission failed and
users can filter retransmission failures by retval.
Compatibility description
=========================
This patch extends the tcp_retransmit_skb tracepoint
by adding a new "err" field at the end of its
existing structure (within TP_STRUCT__entry). The
compatibility implications are detailed as follows:
1) Structural compatibility for legacy user-space tools
Legacy tools/BPF programs accessing existing fields
(by offset or name) can still work without modification
or recompilation.The new field is appended to the end,
preserving original memory layout.
2) Note: semantic changes
The original tracepoint primarily only focused on
successfully retransmitted packets. With this patch,
the tracepoint now can figure out packets that may
terminate early due to specific reasons. For accurate
statistics, users should filter using "err" to
distinguish outcomes.

====================
selftests: drv-net: Test XDP native support
This patch series add tests to validate XDP native support for PASS,
DROP, ABORT, and TX actions, as well as headroom and tailroom adjustment.
For adjustment tests, validate support for both the extension and
shrinking cases across various packet sizes and offset values.
The pass criteria for head/tail adjustment tests require that at-least
one adjustment value works for at-least one packet size. This ensure
that the variability in maximum supported head/tail adjustment offset
across different drivers is being incorporated.
The results reported in this series are based on netdevsim. However,
the series is tested against multiple other drivers including fbnic.
Note: The XDP support for fbnic will be added later.

Add test to validate the headroom adjustment support for both extension
and the shrinking cases. For the extension part, eat up space from
the start of payload data whereas, for the shrinking part, populate
the newly available space with a tag. In the user-space, validate that a
test string is manipulated accordingly.
The negative and positive offset values result in shrinking and growing of
headroom (growing and shrinking of payload) respectively.

Add test to validate support for the two cases of tail adjustment: 1)
tail extension, and 2) tail shrinking across different frame sizes and
offset values. For each of the two cases, test both the single and
multi-buffer cases by choosing appropriate packet size.
The negative offset value result in growing of tailroom (shrinking of
payload) while the positive offset result in shrinking of tailroom
(growing of payload).
Since the support for tail adjustment varies across drivers, classify the
test as pass if at least one combination of packet size and offset from a
pre-selected list results in a successful run. In case of an unsuccessful
run, report the failure and highlight the packet size and offset values
that caused the test to fail, as well as the values that resulted in the
last successful run.
Note: The growing part of this test for netdevsim may appear flaky when
the offset value is larger than 1. This behavior occurs because tailroom
is not explicitly reserved for netdevsim, with 1 being the typical
tailroom value. However, in certain cases, such as payload being the last
in the page with additional available space, the truesize is expanded.
This also result increases the tailroom causing the test to pass
intermittently. In contrast, when tailrrom is explicitly reserved, such
as in the of fbnic, the test results are deterministic.

Octeontx2/CN10k MAC block supports DMAC filters. DMAC filters
can be installed on the interface through ethtool.
When a user installs a DMAC filter, the interface's MAC address
is implicitly added to the filter list. To ensure consistency,
this MAC address must be kept in sync with the pfvf->mac_addr field,
which is used to install MAC-based NPC rules.
This patch updates the pfvf->mac_addr field with the programmed MAC
address and also enables VF interfaces to install DMAC filters.
