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 to run FreeBSD for this project, and I believe the =
Atheros wireless cards I plan to use are supported by ath(4). I'd like =
to find out what else needs to happen to complete the picture. I may =
even go so far as to write some code myself. :)

Is anyone working on this at the moment?

Is it just the rate control that needs to be done or are there other =
parts involved? Is MIMO separate?

Is there a detailed description of the missing pieces somewhere? Or a =
not-very-detailed summary of where to look and what to read to get =
started?

Thanks,

JN
