mac80211: clean up ieee80211_stop_tx_ba_session
There's no sense in letting anything but internal mac80211 functions set the initiator to anything but WLAN_BACK_INITIATOR, since WLAN_BACK_RECIPIENT is only valid when we have received a frame from the peer, which we react to directly in mac80211. The debugfs code I recently added got this wrong as well. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
