Yeah, ok. As for enforcing the traffic, true as well. However, I'd like
mac80211 to help out with this for those drivers that don't do it all in
firmware (all others, I'd assume); it's not overly important that you
switch instantly after receiving the switch beacon, if you take a bit
longer to do that you'll just potentially miss a few packets. No big
deal.

Oh, right, ok.
