From: Ben Greear <greearb@xxxxxxxxxxxxxxx> I found another crash when deleting lots of virtual stations in a congested environment. I think the problem is that the ieee80211_mlme_notify_scan_completed could call ieee80211_restart_sta_timer for a stopped interface that was about to be deleted. Fix similar problem for mesh interfaces as well. Signed-off-by: Ben Greear <greearb@xxxxxxxxxxxxxxx> --- v4: Fix up mesh as well, add check in calling code instead of in the methods that mucks iwth the timers. :100644 100644 67fcfdf... 02e3d75...
