Subject: [PATCH v2] mt76: mt7921: reset msta->airtime_ac while clearing up hw value
Date: Tue, 30 Aug 2022 06:57:44 +0800 [thread overview]
Message-ID: <1c3f22097ebc54bcf055208e8ae5f4d3807513c6.1661813328.git.objelf@gmail.com> (raw)
From: Sean Wang <sean.wang@mediatek.com>
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.

v2: only reset msta->airtime_ac at the assocation
