Benjamin LinandFelix Fietkau d71716d93a wifi: mt76: mt7996: fix incorrect interpretation of EHT MCS caps
The EHT MCS map subfield of 20 MHz-Only is not present in the EHT
capability of AP, so STA does not need to parse the subfield.
Moreover, AP should parse the subfield only if STA is 20 MHz-Only, which
can be confirmed by checking supported channel width in HE capability.

Ming Yen HsiehandFelix Fietkau a84a355d2e wifi: mt76: mt7921: fix country count limitation for CLC
Due to the increase in the number of power tables for 6Ghz on CLC,
the variable nr_country is no longer sufficient to represent the
total quantity. Therefore, we have switched to calculating the
length of clc buf to obtain the correct power table. Additionally,
the version number has been incremented to 1.

Sean WangandFelix Fietkau dbea515141 wifi: mt76: mt7921: reduce the size of MCU firmware download Rx queue
We actually don't need the reserve the 512 entries for the MCU firmware
download Rx queue because the queue was only used in the firmware download
phase to save the most of space and the reduction can significantly help
with reducing latency we spent by ~20% further in resetting the Rx queue
as the device was waking up from deep sleep mode.

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.
