From 509a141e14f794de8fbfe847a3de548ace21d7ec Mon Sep 17 00:00:00 2001 From: Mohammed Shafi Shajakhan Date: Wed, 21 Dec 2011 20:11:35 +0530 Subject: [PATCH v2] mac80211: fix scan state machine when we run high bandwidth UDP traffic and we trigger a scan, the scan state machine seems to be looping in SUSPEND->RESUME->DECISION->SUSPEND and SET_CHANNEL seems to be never called as 'tx_empty' is never true while running UDP traffic. fix this by settting SET_CHANNEL state when we get into RESUME state.
