mac80211: move QOS control helpers into ieee80211.h
Also remove the WLAN_IS_QOS_DATA inline after removing the last two users. This starts moving away from using rx->fc to using the header frame_control directly. Signed-off-by: Harvey Harrison <harvey.harrison@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
