mac80211: Deny TX BA session requests during disassociationmaster-2010-02-10
In associated state, when bringing an interface down, existing BA sessions are torn down. When this is in progress, nothing prevents mac80211 from accepting another BA session start request. Use a new station flag to fix this. Signed-off-by: Sujith <Sujith.Manoharan@atheros.com> Acked-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
