cfg80211: Ignore downstream DEAUTH for authtry_bsses
Paul Stewart [Wed, 8 Jun 2011 12:52:52 +0000 (05:52 -0700)]
Downsteram DEAUTH messages do not refer to a current authentication
attempt -- AUTH responses do.  Therefore we should not allow DEAUTH
from an AP to void state for an AUTH attempt in progress.
