2020-09-24mt76: mt7915: clean up station stats polling and rate control updateFelix Fietkau
Queueing a per-sta work item from the tx free path can become very expensive under load. This work is only supposed to pull rate control stats every second and deal with rate control changes. Additionally, the rate control update code was wrong, because it was confusing bit masks and bit numbers in test_bit. Fix this by introducing a dedicated device work item for rate control updates, and by polling station stats from the phy mac work. Stations requiring polling or rate control updates are added to lists protected by dev->sta_poll_lock. Signed-off-by: Felix Fietkau <nbd@nbd.name>
