lars at pts/3 # wlandebug -i ath0 scan
wlandebug: expecting a wlan interface name
So I ran
# wlandebug -i wlan0 scan
net.wlan.0.debug: 0x0 => 0x200000<scan>
But nothing new then:
lars at pts/3 # ifconfig wlan0 up scan

I re-built world, so the net80211 commit should not be the issue.
The ath device worked with sources from last week, so if there was no
other wireless related commit, I guess the new hal changes caused the
problem. I can back out the hal commit if you don't see anything obvious
in my configuration.
