Series [v2,01/24] mt76: mt7603: fix mixed declarations and code | expand

Commit Message

Felix Fietkau Aug. 27, 2024, 9:29 a.m. UTC
Allows adding stations before assoc, though they are not passed to the
firmware yet at that point.

Signed-off-by: Felix Fietkau <nbd@nbd.name>

v2:
- fix regressions in vif sta entry update
- avoid using vif sta wcid for unicast tx packets
- fix wcid flag update
