Move mt76x02_set_tx_ackto and mt76x02_set_coverage_class routines in mt76x02-lib module in order to be reused by mt76x0 driver. This is a preliminary patch to unify drv_bss_info_changed mac80211 callback between mt76x0 and mt76x2 drivers Signed-off-by: Lorenzo Bianconi <[email protected]> Signed-off-by: Felix Fietkau <[email protected]>
