    rtw88: support wowlan feature for 8822c · 44bc17f7
    Chin-Yen Lee authored
    Wake on WLAN(wowlan) is a feature which allows devices
    to be woken up from suspend state through wlan events.
    
    When user enables wowlan feature and then let the device
    enter suspend state, wowlan firmware will be loaded by
    the driver and periodically monitors wifi packets.
    Power consumption of wifi chip will be reduced in this
    state.
    
    If wowlan firmware detects that specific wlan event
    happens, it will issue wakeup signal to trigger resume
    process. Driver will load normal firmware and let wifi
    chip return to the original state.
    
    Currently supported wlan events include receiving magic packet,
    rekey packet and deauth packet, and disconnecting from AP.
