   3 Subject: [PATCH] mac80211: flush keys for AP mode on ieee80211_do_stop
   4
   5 Userspace can add keys to an AP mode interface before start_ap has been
   6 called. If there have been no calls to start_ap/stop_ap in the mean
   7 time, the keys will still be around when the interface is brought down.
