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>

2020-08-27mt76: mt7615: use v1 MCU API on MT7615 to fix issues with adding/removing ↵Felix Fietkau
stations The implementation of embedding WTBL update inside the STA_REC update is buggy on the MT7615 v2 firmware. This leads to connection issues after a station has connected and disconnected again. Switch to the v1 MCU API ops, since they have received much more testing and should be more stable. On MT7622 and later, the v2 API is more actively used, so we should keep using it as well.

In the implementation of mt7601u_mcu_msg_send(), skb is supposed to be consumed on all execution paths. Release skb before returning if test_bit() fails.
