Subject: [PATCH] wifi: mt76: mt7921: reset msta->airtime_ac while clearing up hw value
Git-commit: 1bf66dc31032ff5292f4d5b76436653f269fcfbd
Patch-mainline: v6.1-rc1
References: git-fixes
We should reset mstat->airtime_ac along with clear up the entries in the
hardware WLAN table for the Rx and Rx accumulative airtime. Otherwsie, the
value msta->airtime_ac - [tx, rx]_last may be a negative and that is not
the actual airtime the device took in the last run.
