Commit 1cc93c48b5 ("selftests/net: packetdrill: remove tests for
tcp_rcv_*big") removed the test for the reverted commit 1d2fbaad7c
("tcp: stronger sk_rcvbuf checks") but also the one for commit
9ca48d616e ("tcp: do not accept packets beyond window").

Restore the test with the necessary adaptation: expect a delayed ACK
instead of an immediate one, since tcp_can_ingest() does not fail
anymore for the last data packet.

Daniel Machon says:

====================
net: sparx5: clean up probe/remove init and deinit paths

This series refactors the sparx5 init and deinit code out of
sparx5_start() and into probe(), adding proper per-subsystem cleanup
labels and deinit functions.

Currently, the sparx5 driver initializes most subsystems inside
sparx5_start(), which is called from probe(). This includes registering
netdevs, starting worker threads for stats and MAC table polling,
requesting PTP IRQs, and initializing VCAP. The function has grown to
handle many unrelated subsystems, and has no granular error handling —
it either succeeds entirely or returns an error, leaving cleanup to a
single catch-all label in probe().

The remove() path has a similar problem: teardown is not structured as
the reverse of initialization, and several subsystems lack proper deinit
functions. For example, the stats workqueue has no corresponding
cleanup, and the mact workqueue is destroyed without first cancelling
its delayed work.

Refactor this by moving each init function out of sparx5_start() and
into probe(), with a corresponding goto-based cleanup label. Add deinit
functions for subsystems that allocate resources, to properly cancel
work and destroy workqueues. Ensure that cleanup order in both error
paths and remove() follows the reverse of initialization order.
sparx5_start() is eliminated entirely — its hardware register setup
is renamed to sparx5_forwarding_init() and its FDMA/XTR setup is
extracted to sparx5_frame_io_init().

Before this series, most init functions live inside sparx5_start() with
no individual cleanup:

  probe():
    sparx5_start():              <- no granular error handling
      sparx5_mact_init()
      sparx_stats_init()           <- starts worker, no cleanup
      mact_queue setup             <- no cancel on teardown
      sparx5_register_netdevs()
      sparx5_register_notifier_blocks()
      sparx5_vcap_init()
    sparx5_ptp_init()

    probe() error path:
      cleanup_ports:
        sparx5_cleanup_ports()
        destroy_workqueue(mact_queue)

After this series, probe() initializes subsystems in order with
matching cleanup labels, and remove() tears down in reverse:

  probe():
    sparx5_pgid_init()
    sparx5_vlan_init()
    sparx5_board_init()
    sparx5_forwarding_init()
    sparx5_calendar_init()         -> cleanup_ports
    sparx5_qos_init()              -> cleanup_ports
    sparx5_vcap_init()             -> cleanup_ports
    sparx5_mact_init()             -> cleanup_vcap
    sparx5_stats_init()            -> cleanup_mact
    sparx5_frame_io_init()         -> cleanup_stats
    sparx5_ptp_init()              -> cleanup_frame_io
    sparx5_register_netdevs()      -> cleanup_ptp
    sparx5_register_notifier_blocks() -> cleanup_netdevs

  remove():
    sparx5_unregister_notifier_blocks()
    sparx5_unregister_netdevs()
    sparx5_ptp_deinit()
    sparx5_frame_io_deinit()
    sparx5_stats_deinit()
    sparx5_mact_deinit()
    sparx5_vcap_deinit()
    sparx5_destroy_netdevs()

With all subsystem initializations moved out, sparx5_start() only sets

Some chipsets, e.g. Wi-Fi 7, will not record SER (system error recovery),
which are triggered by simulations, in the HW counters. Their HW counters
only record the SER happen in field. However for verification, it's still
needed to check if simulations are triggered. So, add SW counters to count
any causes that SER happen. But, SW can only count L1 and L2. SW does not
involve L0 SER, so SW cannot count it.

d03c9ae654 Merge branch 'net-stmmac-further-cleanups'
Russell King says:

====================
net: stmmac: further cleanups

Yet another bunch of patches cleaning up the stmmac driver.

We start off by cleaning up the formatting for stmmac_mac_finish(). Then
remove a plat_dat->port_node which is redundant, followed by several
descriptor methods that aren't called.

We then remove useless dwmac4 interrupt definitions, and realise that
v4.10 definitions are the same as v4.0, so get rid of those as well.
We also remove the write-only priv->hw->xlgmac member.

Next, we change priv->extend_desc and priv->chain_mode to be a boolean
and document what each of these are doing. Also do the same for
dma_cfg->fixed_burst and dma_cfg->mixed_burst.

Then, move the initialisation of dma_cfg->atds into stmmac_hw_init()
as this is where we have all the dependencies for this known, and
simplify its initialisation. Also comment what this is doing.

Finally, move the check that priv->plat->dma_cfg is present and the
programmable burst limit is set into the driver probe rather than
checking it each time we are just about to reset the dwmac core.
It is unnecessary to keep checking this. This makes a platform glue
driver fail early when it hasn't setup everything that's required
rather than when attempting to bring the netdev up for the first time.

and priv->mode (the descriptor mode.)

We don't need to re-evaluate this in stmmac_init_dma_engine() - as the
state that it depends on only changes in stmmac_hwif_init() which is
only called in the probe path. Also, once set, no code clears this
flag.

which is equivalent to dev_fwnode(&pdev->dev) and, as priv->device
will be &pdev->dev, is also equivalent to dev_fwnode(priv->device).

Thus, plat_dat->port_node doesn't provide any extra benefit over
using dev_fwnode(priv->device) directly.

There is one case where port_node is used directly, which can be
found in stmmac_pcs_setup(). This may cause a change of behaviour
as PCI drivers do not populate plat_dat->port_node, but
dev_fwnode(priv->device) may be valid. PCI-based stmmac should
be tested.

b60796c07a wifi: rtw89: 8852a: update supported firmware format to 1
More data will be included in Firmware file and loaded via FW elements.
Unlike other chips, for RF radio, RTL8852A uses rtw89_phy_config_rf_reg
instead of v1, so update loading handling of corresponding FW element.
And then, increase RTL8852A FW format to 1 to prevent old driver from
misusing the data in FW elements.

5cfda90c63 wifi: rtw89: 8852a: move DIG tables to rtw8852a.c
Now, most of PHY parameter tables in driver can be loaded via FW elements.
Plan to generate the corresponding FW elements for 8852A PHY tables. Then,
after FW elements work for a enough time, rtw8852a_table.c can be cleaned
up. However, DIG (dynamic initial gain) tables are legacy for 8852A only,
so FW element doesn't support. Their sizes are not very big, so move them
to rtw8852a.c and keep rtw8852a_table.c for PHY tables which are supported
by FW elements.

No logic is changed.

888226bd56 wifi: rtw89: add general way to generate module firmware string
Module firmware string depends on max format of the firmware. When max
format is 0, the module firmware string will be like XYZ.bin. However,
when max format N > 0, the module firmware string will become XYZ-N.bin.
Originally, when one chip updated its max firmware format from 0 to 1,
the module firmware string also needed to be changed. However, did not
need to do for other cases, e.g. from 1 to 2. It's a bit inconvenient
to always remember that from 0 to 1 is a special case.

So, add a general macro to generate the corresponding module firmware
string based on max firmware format.

Jakub Kicinski says:

====================
selftests: drv-net: iou-zcrx: improve stability and make the large chunk test work

The iou-zcrx test hasn't been passing in NIPA, I assumed it's because
we're missing iouring changes, but it's still failing after the merge
window. Turns out there was a bug in the implementation which was fixed
separately via the iouring tree. With that out of the way the tests
are passing but flaky. Patch 1 deals with the flakiness.

While looking at this I also noticed that the large chunk test isn't
running at all. So fix and enable it (patches 2 and 3).

Commit a32bb32d01 ("selftests: iou-zcrx: test large chunk sizes")
and commit de7c600e2d ("selftests/net: parametrise iou-zcrx.py with
ksft_variants") landed at similar time. The large chunks test was
actually not included in the list of tests, so it never run.
We haven't noticed that it uses the old-style helpers
(_get_combined_channels, _get_current_settings, _set_flow_rule)
that were removed by the other commit.

Rework test_zcrx_large_chunks to reuse the single() setup function
and add it to the ksft_run cases list so it actually gets executed.

When the test's receiver process exits, bkg() returns but the memory
provider may still be attached to the rx queue. The subsequent defer()
that restores tcp-data-split then fails:

  # Exception while handling defer / cleanup (callback 3 of 3)!
  # Defer Exception| net.ynl.pyynl.lib.ynl.NlError:

Add a helper that polls netdev queue-get until no rx queue reports
the io-uring memory provider attribute. Register it as a defer()
just before tcp-data-split is restored as a "barrier".

2d85152020 wifi: rtw89: Turbo mode for RTL8851BU/RTL8852BU
RTL8851BU and RTL8852BU currently have much lower TX speed than
expected, ~100 and ~300 Mbps, respectively. This is because part of the
chip's memory is allocated for some unknown firmware features instead of
the TX buffers.

The vendor drivers have a module parameter called "rtw_quota_turbo_en",
which can be used to choose between full TX speed or the unknown
firmware features. It is on by default.

Change the relevant chip parameters to implement the turbo mode. Do it
only for USB because PCI is already fast even without the turbo mode.
It's unclear if SDIO will need it or not.
