From f823981e288f83113bf1129ff2c94e2fd74a28dd Mon Sep 17 00:00:00 2001 From: Eliad Peller <eliad@wizery.com> Date: Wed, 27 Jun 2012 14:18:22 +0300 Subject: [PATCH] mac80211: flush queues before deauth/disassoc On deauth/disassoc we tear down all BA sessions. These DELBA packets are sent on the appropriate TID, while deauth/disassoc is always sent on VO. This sometimes ends with the DELBA being sent after the deauth was already sent. Fix it by flushing all the pending frames before sending deauth/disassoc.
