wi(4) IEEE_80211_S_SCAN support?

Hi everyone,

Okay, only after banging my head against the wall for a couple hours
trying to figure out why wpa_supplicant doesn't like my old prism2 card
(I'm pretty sure it can't do WPA but I just want to auto-assign WEP
keys...), I think it's because the wi driver just doesn't implement the
IEEE_80211_S_SCAN state.

It wasn't until discovering that "ifconfig wi0 scan" just sits there
doing nothing that I began to suspect the new wlan infrastructure.

So, is anybody working on the wi driver currently?  I'm game for taking
a stab at implementing those but I don't want to duplicate any effort
that's already underway.

I also wanted to check because maybe there are some gotchas that
resulted in it not being implemented in the first place :)
