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 Signed-off-by: Deren Wu --- .../wireless/mediatek/mt76/mt76_connac_mcu.c | 2 + .../net/wireless/mediatek/mt76/mt7921/main.c | 49 +++++++++++++++---- .../net/wireless/mediatek/mt76/mt7921/mcu.c | 5 +- .../wireless/mediatek/mt76/mt7921/mt7921.h | 2 + 4 files changed, 45 insertions(+), 13 deletions(-) diff --git a/drivers/net/wireless/mediatek/mt76/mt76_connac_mcu.c b/drivers/net/wireless/mediatek/mt76/mt76_connac_mcu.c index faa279bbbcb2..7eb23805aa94 100644 --- a/drivers/net/wireless/mediatek/mt76/mt76_connac_mcu.c +++ b/drivers/net/wireless/mediatek/mt76/mt76_connac_mcu.c @@ -1403,6 +1403,8 @@ int mt76_connac_mcu_uni_add_bss(struct mt76_phy *phy, else conn_type = CONNECTION_INFRA_AP;
