From 19c3b8303d4686aa373c669ee833609b3fb403cc Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 1 Aug 2012 20:13:36 +0200 Subject: [PATCH] mac80211: reset station MLME flags upon new association When associating anew, the old station MLME flags should be cleared. The only exception is the 40 MHz disable flag as it might have been set while the channel was set in a previous authentication attempt so it needs to be kept intact.
