[PATCH] softmac: Fixed handling of deassociation from AP

From: Ulrich Kunitz
Date: Sun Dec 03 2006 - 10:32:29 EST


In 2.6.19 a deauthentication from the AP doesn't start a
reassociation by the softmac code. It appears that
mac->associnfo.associating must be set and the
ieee80211softmac_assoc_work function must be scheduled. This patch
fixes that.
