[PATCH v2 0/5] mt76: move common beacon code in mt76 module

[PATCH v2 0/5] mt76: move common beacon code in mt76 module

[Lorenzo Bianconi]

Move beacon data structures shared between mt76x02 and mt7603 drivers
in mt76_dev.
Enable/disable pre_tbtt_tasklet tasklet in mt7603_set_channel

Changes since v1:
- added new patch: 'mt76: do not enable/disable pre_tbtt_tasklet in
  scan_start/scan_complete'

Lorenzo Bianconi (5):
  mt76: do not enable/disable pre_tbtt_tasklet in
    scan_start/scan_complete
  mt76: move beacon_int in mt76_dev
  mt76: move beacon_mask in mt76_dev
  mt76: move pre_tbtt_tasklet in mt76_dev
  mt76: mt7603: enable/disable pre_tbtt_tasklet in mt7603_set_channel
