Hello,

It seems that the option is already enabled in the CURRENT kernel:

[root at e6330-r314251 /usr/src]# grep IEEE80211_DEBUG ./sys/amd64/conf/GENERIC
options 	IEEE80211_DEBUG		# enable debug msgs

I made the tool and run it parralel to the SCP (from the rtwn0 to the ath0)
which is going dowm from around 2MB/s to some 100KB/s; see below;
