nl80211/cfg80211: add STA WME parameters
Add new NL80211_ATTR_STA_WME nested attribute that contains wme params needed by the low-level driver (uapsd_queues and max_sp). Add these params to the station_parameters struct as well. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
