From 3d2abdfdf14f4d6decc2023708211e19b096f4ca Mon Sep 17 00:00:00 2001 From: Eliad Peller Date: Tue, 4 Sep 2012 17:44:45 +0300 Subject: [PATCH] mac80211: clear bssid on auth/assoc failure ifmgd->bssid wasn't cleared properly in some auth/assoc failure cases, causing mac80211 and the low-level driver to go out of sync. Clear ifmgd->bssid on failure, and notify the driver.
