2020-12-04mt76: mt7915: query station rx rate from firmwareFelix Fietkau5-3/+127
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 Fietkau1-0/+1
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.

When looking for a MAC address slot, start by using main BSSID slots 1-3, afterwards use 16 repeater mode BSSID slots, then start using the slots usually used for AP mode.

2020-12-04mt76: mt7615: add debugfs knob for setting extended local mac addressesFelix Fietkau3-0/+101
This is primarily for testing and can be used in combination with monitor mode to make the card respond to packets sent to a specific MAC address. For now this is only exposed as a debug/testing feature, later on the approach might be used to support more concurrent station interfaces Signed-off-by: Felix Fietkau <[email protected]>
