2022-07-11mt76: mt7921: fix command timeout in AP stop periodDeren Wu
Due to AP stop improperly, mt7921 driver would face random command timeout by chip fw problem. Migrate AP start/stop process to .start_ap/.stop_ap and congiure BSS network settings in both hooks. The new flow is shown below. * AP start .start_ap() configure BSS network resource set BSS to connected state .bss_info_changed() enable fw beacon offload * AP stop .bss_info_changed() disable fw beacon offload (skip this command) .stop_ap() set BSS to disconnected state (beacon offload disabled automatically) destroy BSS network resource Fixes: 116c69603b01 ("mt76: mt7921: Add AP mode support") Signed-off-by: Sean Wang <sean.wang@mediatek.com> Signed-off-by: Deren Wu <deren.wu@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
