please avoid patches that modify both cfg80211 and mac80211 unless
they're really small.

Why do you need your own timer?

we have a general interface work struct.

Why do you need to queue SKBs?

Why would you ever need this flexibility? It seems pointless to prepare
for it - I'm guessing you're never going to implement it?

NACK. Please make a proper "join OCB" operation etc. In the wireless
stack, "ifup" shouldn't be used to start real operation.

use a delayed work struct?
I don't even see a call to turn on the carrier?
Anyway I think you should have some OCB join method in the cfg80211 API
even if there's nothing really to do... at minimum, you need to specify
a channel somehow!
