So I'd assumed, but it wasn't clear to me which node you eventually
wanted to get at. When I run sysctl -a|egrep '802|ath|wlan' |grep debug
net.link.ieee80211.debug = 0
net.link.ieee80211.rssadapt.debug = 0
net.link.ieee80211.vap0.debug = 0
hw.ath.debug = 0
hw.ath0.debug = 0
Which is being tweaked here?
