available when debugging, but hard to correlate
between different sources, so add a trace event
for all mac80211 debug messages.

+ Select this option to have mac80211 register the
+ mac80211_msg trace subsystem with tracepoints to
+ collect all debugging messages, independent of
+ printing them into the kernel log.
+
+ The overhead in this option is that all the messages
+ need to be present in the binary and formatted at
+ runtime for tracing.
