From 25420604c8967ff24f087dd7b9cd4b278567d39a Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 13 Mar 2009 11:43:36 +0100 Subject: mac80211: stop queues across suspend/resume Even though userland probably cannot submit packets, there might still be some coming, and that's no good when the driver doesn't expect them. Stop the queues across suspend/resume. Signed-off-by: Johannes Berg Signed-off-by: John W.
