Not like I care about that at all ... we change things all the time and
break drivers in the process. Is it even feasible to have non-upstream
drivers on the current wireless stack? I'd think you'd have to dedicate
one person full time to following our mac80211 changes ;-)

Well so obviously we need things like VHT capability stuff (advertising,
in scans, in assoc, for AP/GO mode in station info). I suspect you're
talking only about the regulatory/channel stuff? Mostly I'm confused
about the split channel thing there but I suppose regulatory-wise it's
just like using two channels at the same time.

Does anyone here have an "official opinion"? I doubt it :)
