mac80211: don't duplicate station QoS capability data
We currently track the QoS capability twice: for all peer stations in the WLAN_STA_WME flag, and for any clients associated to an AP interface separately for drivers in the sta->sta.wme field. Remove the WLAN_STA_WME flag and track the capability only in the driver-visible field, getting rid of the limitation that the field is only valid in AP mode. Reviewed-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
