Sean WangandFelix Fietkau 7f65b1b28b wifi: mt76: connac: Extend mt76_connac_mcu_uni_add_dev for MLO
This commit extends the `mt76_connac_mcu_uni_add_dev` function to include
support for Multi-Link Operation (MLO). Additionally, backward
compatibility for MT7921 is preserved, enabling seamless integration with
existing setups.

Aditya Kumar SinghandFelix Fietkau 82a452919f wifi: mac80211: handle ieee80211_radar_detected() for MLO
Currently DFS works under assumption there could be only one channel
context in the hardware. Hence, drivers just calls the function
ieee80211_radar_detected() passing the hardware structure. However, with
MLO, this obviously will not work since number of channel contexts will be
more than one and hence drivers would need to pass the channel information
as well on which the radar is detected.

Also, when radar is detected in one of the links, other link's CAC should
not be cancelled.

Hence, in order to support DFS with MLO, do the following changes -
  * Add channel context conf pointer as an argument to the function
    ieee80211_radar_detected(). During MLO, drivers would have to pass on
    which channel context conf radar is detected. Otherwise, drivers could
    just pass NULL.
  * ieee80211_radar_detected() will iterate over all channel contexts
    present and
  	* if channel context conf is passed, only mark that as radar
  	  detected
  	* if NULL is passed, then mark all channel contexts as radar
  	  detected
  	* Then as usual, schedule the radar detected work.
  * In the worker, go over all the contexts again and for all such context
    which is marked with radar detected, cancel the ongoing CAC by calling
    ieee80211_dfs_cac_cancel() and then notify cfg80211 via
    cfg80211_radar_event().
  * To cancel the CAC, pass the channel context as well where radar is
    detected to ieee80211_dfs_cac_cancel(). This ensures that CAC is
    canceled only on the links using the provided context, leaving other
    links unaffected.

This would also help in scenarios where there is split phy 5 GHz radio,
which is capable of DFS channels in both lower and upper band. In this
case, simultaneous radars can be detected.

Wang ZhaoandFelix Fietkau 9ef06028d4 wifi: mt76: mt7921s: fix workqueue problem causes STA association fail
The ieee80211_queue_work function queues work into the mac80211
local->workqueue, which is widely used for mac80211 internal
work processes. In the mt76 driver, both the mt76-sido-status and
mt76-sdio-net threads enqueue workers to the workqueue with this
function. However, in some cases, when two workers are enqueued
to the workqueue almost simultaneously, the second worker may not
be scheduled immediately and may get stuck for a while.
This can cause timing issues. To avoid these timing
conflicts caused by worker scheduling, replace the worker
with an independent thread.

Felix Fietkau 269df4b01f wifi: mt76: fix rx checksum offload on mt7615/mt7915/mt7921
Checking the relevant rxd bits for the checksum information only indicates
if the checksum verification was performed by the hardware and doesn't show
actual checksum errors. Checksum errors are indicated in the info field of
the DMA descriptor. Fix packets erroneously marked as CHECKSUM_UNNECESSARY
by checking the extra bits as well.
Those bits are only passed to the driver for MMIO devices at the moment, so
limit checksum offload to those.
