Well, the first thing to establish is whether it's occuring in
net80211 or the driver. I _think_ it's a net80211 problem, where
dhclient is sending a frame to an interface that isn't yet ready. It's
yet another race condition that I must've uncovered when I made the
switch to if_transmit() in net80211.

Yes, I'd love it if someone looked into it for me. :)
