The hard part is implementing this in drivers. It's not even guaranteed 
that it will work with your cards. And if it does, it's because someone 
invested some of his time to implement it in mac80211.

I started working on this, but i found an acceptable hack^Walternative 
solution for my case, and forgot about this. But i might want to 
reconsider it.
