Not sure about the wpi complaint. For ath I need mac+phy revs and any
regulatory setting (output sysctl dev.ath.0 will show it). You might
also enable scan debug to see if the ap shows up but isn't recorded for
some reason; e.g. wlandebug -i ath0 scan.
I committed major hal changes as a single commit so you can easily back
it out to see if it's the reason. The other recent changes to net80211
should not matter if you rebuilt world to match the kernel (the size of
the channel structure changed so kernel+apps need to match).
