From 0a2b8bb24d4eb67788edd71d1ef8aa86c2e17e0f Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 7 Jul 2009 13:46:22 +0200 Subject: mac80211: driver operation debugging This makes mac80211 use the event tracing framework to log all operations as given to the driver. This will need to be extended with more information, but as a start it should be good. Signed-off-by: Johannes Berg Signed-off-by: John W.
