Series [v2] mt76: mt7615: enable beacon filtering by default for offload fw | expand

Commit Message

Lorenzo Bianconi Sept. 30, 2020, 8:57 a.m. UTC 
In order to reduce cpu cycles, enable hw beacon filter by default if
the device is running offload fw with sta only interfaces.
Disable runtime pm for multi-vif scenario.

Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org>

Changes since v1:
- disable hw beacon filtering for multi-vif scenario.
- disable runtime pm for multi-vif scenario.
