From 3fae0273168026ed7b6065674f1410f531d58164 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 22 Jun 2012 13:36:25 +0200 Subject: mac80211: trace debug messages It can be very useful to have all debug messages available when debugging, but hard to correlate between different sources, so add a trace event for all mac80211 debug messages.
