There's a race between driver and fw on some tx/rx control registers
when setting ifs, which will cause accidental hw queue pause problems.
Avoid this by setting ifs time with bss_info mcu command.

When in suspend mode, WoW (Wake-on-WLAN) fails to wake the system remotely

old STA_REC_KEY_V2 command will send incorrect parameters to the firmware.
Therefore, STA_REC_KEY_V3 has been introduced as a replacement for it.

When enter suspend/resume while in a connected state, the upper layer
will trigger disconnection before entering suspend, and at the same time,
it will trigger regd_notifier() and update CLC, causing the CLC event to
not be received due to suspend, resulting in a command timeout.
Therefore, the update of CLC is postponed until resume, to ensure data
consistency and avoid the occurrence of command timeout.

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.
