    mac80211: add U-APSD client support · ab13315a
    Kalle Valo authored
    Add Unscheduled Automatic Power-Save Delivery (U-APSD) client support. The
    idea is that the data frames from the client trigger AP to send the buffered
    frames with ACs which have U-APSD enabled. This decreases latency and makes it
    possible to save even more power.
    Driver needs to use IEEE80211_HW_UAPSD to enable the feature. The current
    implementation assumes that firmware takes care of the wakeup and
    hardware needing IEEE80211_HW_PS_NULLFUNC_STACK is not yet supported.
    Tested with wl1251 on a Nokia N900 and Cisco Aironet 1231G AP and running
    various test traffic with ping.
