2025-01-27wifi: mt76: move napi_enable() from under BHJakub Kicinski
mt76 does a lot of: local_bh_disable(); napi_enable(...napi); napi_schedule(...napi); local_bh_enable(); local_bh_disable() is not a real lock, its most likely taken because napi_schedule() requires that we invoke softirqs at some point. napi_enable() needs to take a mutex, so move it from under the BH protection.

2025-01-14wifi: mt76: mt7996: add implicit beamforming support for mt7992Howard Hsu
The configuration of mt7992 iBF has some differences to mt7996, rework related code to make it work. Also, most of our chipsets support iBF only on HT and VHT mode, except mt7992 variant that has 5T on 5GHz band also supports iBF on HE and EHT mode.

2025-01-14wifi: mt76: mt7996: fix beacon command during disablingMichael-CY Lee
When stopping AP, mac80211 frees beacon template before it calls driver's stop_ap operation. In other words, on the path of stopping AP, ieee80211_beacon_get_template() must returns NULL in mt7996_mcu_add_beacon(). In such case mt7996 immediately returns -EINVAL without telling FW to disable the beacon. This commit refactors mt7996_mcu_add_beacon() so that FW can be correctly informed when disabling AP interface.

2025-01-14wifi: mt76: mt7925: add handler to hif suspend/resume eventQuan Zhou

Add flow to handle hif_ctrl event to avoid command timeout. We also exented API mt76_connac_mcu_set_hif_suspend for connac3 this time.
