Trace all mac80211 debug messages

configname: CONFIG_MAC80211_MESSAGE_TRACING

Linux Kernel Configuration
└─>Networking support
└─>Wireless
└─>Trace all mac80211 debug messages
In linux kernel since version 3.1 (release Date: 2011-10-24)  
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.
