Some firmware versions do not support the host capability QMI request.
Since this request occurs before firmware-N.bin and board-M.bin are
loaded, the quirk cannot be expressed in the firmware itself.
The root cause is unclear, but there appears to be a generation of
firmware that lacks host capability support.
Without this quirk, ath10k_qmi_host_cap_send_sync() returns
QMI_ERR_MALFORMED_MSG_V01 before loading the firmware. This error is not
fatal - Wi-Fi services still come up successfully if the request is simply
skipped.
Add a device-tree quirk to skip the host capability QMI request on devices
whose firmware does not support it.
For example, firmware build
"QC_IMAGE_VERSION_STRING=WLAN.HL.2.0.c3-00257-QCAHLSWMTPLZ-1"
on Xiaomi Poco F1 phone requires this quirk.

Just use the michael_mic() function from cfg80211 instead of a local
implementation of it using the crypto_shash API.
Note: when the kernel is booted with fips=1,
crypto_alloc_shash("michael_mic", 0, 0) always returned
ERR_PTR(-ENOENT), because Michael MIC is not a "FIPS allowed" algorithm.
For now, just preserve that behavior exactly, to ensure that TKIP is not
allowed to be used in FIPS mode. This logic actually seems to disable
the entire driver in FIPS mode and not just TKIP, but that was the
existing behavior. Supporting this driver in FIPS mode, if anyone
actually needs it there, should be a separate commit.

Rename the driver-local michael_mic() function to libipw_michael_mic()
to prevent a name conflict with the common michael_mic() function.
Note that this code will be superseded later when libipw starts using
the common michael_mic(). This commit just prevents a bisection hazard.

Currently, ath12k AHB (in IPQ5332) uses SCM calls to authenticate the
firmware image to bring up userpd. From IPQ5424 onwards, Q6 firmware can
directly communicate with the Trusted Management Engine - Lite (TME-L),
eliminating the need for SCM calls for userpd bring-up.
Hence, to enable IPQ5424 device support, use qcom_mdt_load_no_init() and
skip the SCM call as Q6 will directly authenticate the userpd firmware.

Add ath12k_hw_params for the ath12k AHB-based WiFi 7 device IPQ5424.
The WiFi device IPQ5424 is similar to IPQ5332. Most of the hardware
parameters like hw_ops, wmi_init, ring_mask, etc., are the same between
IPQ5424 and IPQ5332, hence use these same parameters for IPQ5424.

Recent commit [1] moved station statistics collection to an earlier stage
of the disconnect flow. With this change in place, ath10k fails to resolve
the station entry when handling a peer stats event triggered during
disconnect, resulting in log messages such as:
wlp58s0: deauthenticating from 74:1a:e0:e7:b4:c8 by local choice (Reason: 3=DEAUTH_LEAVING)
ath10k_pci 0000:3a:00.0: not found station for peer stats
ath10k_pci 0000:3a:00.0: failed to parse stats info tlv: -22
The failure occurs because ath10k relies on ieee80211_find_sta_by_ifaddr()
for station lookup. That function uses local->sta_hash, but by the time
the peer stats request is triggered during disconnect, mac80211 has
already removed the station from that hash table, leading to lookup
failure.
Before commit [1], this issue was not visible because the transition from
IEEE80211_STA_NONE to IEEE80211_STA_NOTEXIST prevented ath10k from sending
a peer stats request at all: ath10k_mac_sta_get_peer_stats_info() would
fail early to find the peer and skip requesting statistics.
Fix this by switching the lookup path to ath10k_peer_find(), which queries
ath10k's internal peer table. At the point where the firmware emits the
peer stats event, the peer entry is still present in the driver's list,
ensuring lookup succeeds.

In single-wiphy design, when more than one radio is registered as a
single-wiphy in the mac80211 layer, the following warnings are seen:
1. debugfs: File 'ath12k' in directory 'phy0' already present!
2. debugfs: File 'simulate_fw_crash' in directory 'pci-0000:57:00.0' already present!
debugfs: File 'device_dp_stats' in directory 'pci-01777777777777777777777:57:00.0' already present!
When more than one radio is registered as a single-wiphy, symlinks for
all the radios are created in the same debugfs directory:
/sys/kernel/debug/ieee80211/phyX/ath12k, resulting in warning 1. When a
symlink is created for the first radio, since the 'ath12k' directory is
not present, it will be created and no warning will be thrown. But when
symlink is created for more than one radio, since the 'ath12k'
directory was already created for symlink for radio 1, a warning is
thrown complaining that 'ath12k' directory is already present. To resolve
warning 1, create symlink for each radio in separate debugfs directories.
For the first radio, the symlink will always be the 'ath12k' directory.
This ensures that the existing directory structure is retained for
single-wiphy and multi-wiphy architectures. In single-wiphy architecture
with multiple radios, create symlink in separate debugfs directories
introduced by mac80211.
Existing debugfs directory in single-wiphy architecture:
/sys/kernel/debug/ieee80211/phyX/ath12k is a symlink to
/sys/kernel/debug/ath12k/pci-0001:01:00.0/macY
Proposed debugfs directory in single-wiphy architecture with one radio:
/sys/kernel/debug/ieee80211/phyX/ath12k is a symlink to
/sys/kernel/debug/ath12k/pci-0001:01:00.0/mac0
Proposed debugfs directory in single-wiphy architecture with more than
one radio:
/sys/kernel/debug/ieee80211/phyX/radio0/ath12k is a symlink to
/sys/kernel/debug/ath12k/pci-0001:01:00.0/mac0 and
/sys/kernel/debug/ieee80211/phyX/radioY/ath12k is a symlink to
/sys/kernel/debug/ath12k/pci-0001:01:00.0/macY
Where X is phy index and Y is radio index, seen in
'iw phyX info | grep Idx'. Two symlinks for the first radio are to ensure
compatibility with the existing design. Add radio_idx inside ar, to track
the radio index in probing order.
API ath12k_debugfs_pdev_create() that creates SoC entries is called more
than once when hardware group starts up, resulting in warning 2. To
resolve this warning, remove all other calls to this API and add one
inside the ath12k_core_pdev_create(). This API carries all pdev-specific
initializations and can conveniently hold a call to
ath12k_debugfs_pdev_create().

Currently, a vdev that is created is considered active for partner link
population. In case of an MLD station, non-associated link vdevs can be
created but not started. Yet, they are added as partner links. This leads
to the creation of stale FW partner entries which accumulate and cause
assertions.
To resolve this issue, check if the vdev is started and operating on a
chosen frequency, i.e., arvif->is_started, instead of checking if the vdev
is created, i.e., arvif->is_created. This determines if the vdev is active
or not and skips adding it as a partner link if it's inactive.

ath12k_ah_to_ar() is returning radio from the given hardware based on the
radio index passed. But, the variable that radio index is received at is
wrongly named 'hw_link_id', which points to the hardware link index that

Ping-Ke Shih says:
==================
rtw-next patches for -next
Improve MLO and some random fixes. Notable changes are:
* drop usb device reference across drivers
rtw89:
* add RTL8922DE but not enabled yet, because BT coexistence is still
cooking.
* add USB RX aggregation to improve performance.
* add USB TX flow control by tracking in-flight URBs.

The driver tries to load optional firmware files, specific to
the actual board compatible. These might not exist resulting in a warning
like this:
brcmfmac mmc2:0001:1: Direct firmware load for brcm/brcmfmac4373-sdio.tq,imx93-tqma9352-mba93xxla-mini.bin failed with error -2
Silence this by using firmware_request_nowait_nowarn() for all firmware
loads which use brcmf_fw_request_done_alt_path() as callback. This one
handles optional firmware files.

Do not latch these flags, they should be re-evaluated for each
iteration of the loop.
Concretely, rxq->free_count is incremented during the loop so the
__GFP_NOWARN decision may be stale. There may be other reasons to
require the re-evaluation too.

Fix 2 issues spotted by AI[0]:
1. Missing space after the full stop.
2. Wrong GFP flags are printed.
And also switch to %pGg for the GFP flags. This produces nice readable

USB drivers bind to USB interfaces and any device managed resources
should have their lifetime tied to the interface rather than parent USB
device. This avoids issues like memory leaks when drivers are unbound
without their devices being physically disconnected (e.g. on probe
deferral or configuration changes).
Fix the USB anchor lifetime so that it is released on driver unbind.

rtw89_usb_ops_check_and_reclaim_tx_resource() returns a hardcoded
placeholder value (42) instead of actual TX resource availability.
This violates mac80211's flow control contract, preventing backpressure
and causing uncontrolled URB accumulation under sustained TX load.
Fix by adding per-channel atomic counters (tx_inflight[]) that track
in-flight URBs. Increment before usb_submit_urb() with rollback on
failure, decrement in the completion callback, and return the
remaining capacity to mac80211. The firmware command channel (CH12)
always returns 1 since it has its own flow control.
The pre-increment pattern prevents a race where USB core completes the
URB on another CPU before the submitting code increments the counter.
128 URBs per channel provides headroom for RTL8832CU at 160 MHz
bandwidth. Tested on RTL8852AU (USB3 80 MHz) where 64 and 128 showed
equivalent throughput, and on RTL8832AU where 128 sustained full
throughput under 8-stream parallel load.
Tested on D-Link DWA-X1850 (RTL8832AU), kernel 6.19.8, Fedora 43:
Unpatched -> Patched (128 URBs)
USB3 5GHz UL: 844 -> 837 Mbps (no regression)
USB3 5GHz retx: 3 -> 0
USB3 2.4GHz UL: 162 -> 164 Mbps (no regression)
4-stream UL: 858 -> 826 Mbps (within variance)
8-stream UL: 872 -> 826 Mbps (within variance)
UDP flood: 0% loss (690K datagrams)
60-second soak: 855 Mbps, 0 retransmits

The chips ops related to RF calibration include init, init_late, channel,

is ready, so receiving C2H event is possible. The ops channel is the main
function that do all RF calibration on operating channel.
The ops band_change and scan are to reset RF calibration because channel is
switching at these moment, we need to reset RF state. The ops track is to
monitor temperature to check if re-calibrate RF again.

Sometimes while watching a Youtube video with Bluetooth headphones the
audio has a lot of interruptions, because the 5th byte of the BT info
sent by RTL8821AU has strange values, which result in
coex_stat->bt_hid_pair_num being 2 or 3. When this happens
rtw_coex_freerun_check() returns true, which causes
rtw_coex_action_wl_connected() to call rtw_coex_action_freerun() instead
of rtw_coex_action_bt_a2dp().
The RTL8821AU vendor driver doesn't do anything with the 5th byte of the
BT info, so ignore it here as well.
