Is 802.11n rate control being worked on?

I am working on a network scenario which would benefit greatly from the MIMO features and higher bandwidth of 802.11n. It's my understanding that 11n is not fully supported in FreeBSD since there is no appropriate rate control algorithm in the tree. Is that still the case? I would _really_ like
