[][MAC80211][core][mt76][Airtime Fairness Scheduler Feature Off]
[Description]
Change Airtime Fairness Scheduler feature
mac80211: airtime_flags depends on NL80211_EXT_FEATURE_AIRTIME_FAIRNESS
mt76: Airtime Fairness Scheduler feature disbale
MAC80211 provides three Fairness Componments (ATF/AQL/AQM)
To fit with Mediatek WiFi6 Feature, will default disable ATF scheduler.
The airtime info is registered by mt76 which reads it from WTBL and
MAC80211 grant permission based on a historical average of airtime usage.
When ATF on, packets per station is unbalance a split second and
cause firmware algorithm hard to send HEMU PPDUs.
