From 62fe778412b36791b7897cfa139342906fbbf07b Mon Sep 17 00:00:00 2001 From: Helmut Schaa Date: Mon, 18 Apr 2011 15:26:37 +0200 Subject: [PATCH] rt2x00: Fix stuck queue in tx failure case Since commit 0b7fde54f94979edc67bbf86b5adba702ebfefe8 "rt2x00: Protect queue control with mutex" rt2x00 used rt2x00queue_pause_queue for stopping a tx queue in mac80211. But in case of a failure in the tx path rt2x00 still called ieee80211_stop_queue which stopped the queue but prevented rt2x00queue_unpause_queue to wake the queue up again resulting in a stuck tx queue. Fix this by also using rt2x00queue_pause_queue in case of tx failures. Signed-off-by: Helmut Schaa Signed-off-by: Ivo van Doorn Signed-off-by: John W.
