14a7ba034f wifi: mt76: mt792x: add PSE handling barrier for the large MCU cmd
Add a dummy register read in mt76_connac_mcu_rate_txpower_band() to act as
a PSE barrier. This would release PSE pages and prevents buffer underflow
issues when handling MCU commands with larger payloads without the response

This is a prerequisite patch before enabling MT7902 PCIe and SDIO support.

37d5b68ab5 wifi: mt76: fix backoff fields and max_power calculation
The maximum power value may exist in either the data or backoff field.
Previously, backoff power limits were not considered in txpower reporting.
This patch ensures mt76 also considers backoff values in the SKU table.

Also, each RU entry (RU26, RU52, RU106, BW20, ...) in the DTS corresponds
to 10 stream combinations (1T1ss, 2T1ss, 3T1ss, 4T1ss, 2T2ss, 3T2ss,
4T2ss, 3T3ss, 4T3ss, 4T4ss).

For beamforming tables:
- In connac2, beamforming entries for BW20~BW160, and OFDM do not include
  1T1ss.
- In connac3, beamforming entries for BW20~BW160, and RU include 1T1ss,
  but OFDM beamforming does not include 1T1ss.

Non-beamforming and RU entries for both connac2 and connac3 include 1T1ss.

mt76_remain_on_channel() and mt76_roc_complete() call mt76_set_channel()

d5059e52fd wifi: mt76: mt7921: fix potential deadlock in mt7921_roc_abort_sync
roc_abort_sync() can deadlock with roc_work(). roc_work() holds
dev->mt76.mutex, while cancel_work_sync() waits for roc_work()

sides block and no progress is possible.

This deadlock can occur during station removal when
mt76_sta_state() -> mt76_sta_remove() -> mt7921_mac_sta_remove() ->
mt7921_roc_abort_sync() invokes cancel_work_sync() while
roc_work() is still running and holding dev->mt76.mutex.

This avoids the mutex deadlock and preserves exactly-once
work ownership.

fdfa39f9f4 wifi: mt76: mt7921: fix ROC abort flow interruption in mt7921_roc_work
The mt7921_set_roc API may be executed concurrently with mt7921_roc_work,
specifically between the following code paths:

- The check and clear of MT76_STATE_ROC in mt7921_roc_work:
    if (!test_and_clear_bit(MT76_STATE_ROC, &phy->mt76->state))
        return;

- The execution of ieee80211_iterate_active_interfaces.

This race condition can interrupt the ROC abort flow, resulting in
the ROC process failing to abort as expected.

To address this defect, the modification of MT76_STATE_ROC is now
protected by mt792x_mutex_acquire(phy->dev). This ensures that
changes to the ROC state are properly synchronized, preventing
race conditions and ensuring the ROC abort flow is not interrupted.

c41075ce8c wifi: mt76: Fix memory leak after mt76_connac_mcu_alloc_sta_req()
mt76_connac_mcu_alloc_sta_req() allocates an skb which is expected to
be freed eventually by mt76_mcu_skb_send_msg(). However, currently if
an intermediate function fails before sending, the allocated skb is
leaked.

Specifically, mt76_connac_mcu_sta_wed_update() and
mt76_connac_mcu_sta_key_tlv() may fail, leading to an immediate memory
leak in the error path.

Fix this by explicitly freeing the skb in these error paths.
Commit 7c0f63fe37 ("wifi: mt76: mt7996: fix memory leak on
mt7996_mcu_sta_key_tlv error") made a similar change.

4d0bf21e3e wifi: mt76: mt7921: Place upper limit on station AID
Any station configured with an AID over 20 causes a firmware crash.
This situation occurred in our testing using an AP interface on 7922
hardware, with a modified hostapd, sourced from Mediatek's OpenWRT
feeds.

In stock hostapd, station AIDs begin counting at 1, and this
configuration is prevented with an upper limit on associated stations.
However, the modified hostapd began allocation at 65, which caused the
firmware to crash. This fix does not allow these AIDs to work, but will
prevent the firmware crash.

This crash was only seen on IFTYPE_AP interfaces, and the fix does not
appear to have an effect on IFTYPE_STATION behavior.

The mt7996 driver currently checks the MT_RXD3_NORMAL_FCS_ERR bit in
rxd1 whereas other Connac3-based drivers(mt7925) correctly check this
bit in rxd3.

Since the MT_RXD3_NORMAL_FCS_ERR bit is defined in the fourth RX
descriptor word (rxd3), update mt7996 to use the proper descriptor
field. This change aligns mt7996 with mt7925 and the rest of the
Connac3 family.

3416394219 wifi: mt76: fix list corruption in mt76_wcid_cleanup
mt76_wcid_cleanup() was not removing wcid entries from sta_poll_list
before mt76_reset_device() reinitializes the master list. This leaves
stale pointers in wcid->poll_list, causing list corruption when
mt76_wcid_add_poll() later checks list_empty() and tries to add the
entry back.

The fix adds proper cleanup of poll_list in mt76_wcid_cleanup(),
matching how tx_list is already handled. This is similar to what
mt7996_mac_sta_deinit_link() already does correctly.

Fixes list corruption warnings like:
  list_add corruption. prev->next should be next (ffffffff...)
