2020-12-04mt76: mt7915: query station rx rate from firmwareFelix Fietkau
When per-packet rate reporting is enabled, the hardware can get stuck under some conditions. It self-recovers quickly, but in practice this leads to reduced performance. In order to avoid running into this issue, disable per-packet rate reporting by default and query the rx rate from firmware instead, unless monitor mode is enabled.

2020-12-04mt76: mt7915: fix processing txfree eventsFelix Fietkau
In the MT7915 info, the fields for the WLAN index / queue overlap with the token id, and the MT_TX_FREE_PAIR bit indicates, which one is present. If MT_TX_FREE_PAIR is set, skip processing the token index, since the data will not be valid. This fixes accidentally freeing tokens which are still in use by the hardware with a wrong station pointer. Signed-off-by: Felix Fietkau <nbd@nbd.name>
