mac80211: add U-APSD client support
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. Signed-off-by: Kalle Valo <kalle.valo@nokia.com> Signed-off-by: John W.
