Since wireless drivers will need to be ported again from FreeBSD due to the massive net80211 changes I have on my branch, a new firmware interface will probably be needed.

I'm unhappy with the ratectl stuff, really. I think it needs to be rewritten to cope with the changes to the ratectl algorithms from FreeBSD. The other route would be to ditch wlan_ratectl and keep everything in sync with FreeBSD.
