Hi,

There's some work done on the ath(4) hardware for 11a parts done by Sam
Leffler. I fixed it for 11n parts. It's in FreeBSD-HEAD.

I figured out how to get it mostly working on the AR93xx/AR94xx parts too
but it turns out there are some significant hardware changes in how the MAC
schedules packets that a whole lot of work needs to be done to get
effective TDMA on those parts.

If you're interested in it I can brain dump where I was at with it!
