You need an NDA with Atheros and recent proprietary driver for AR9590. 
AFAIK this feature is not documented in datasheets so you need
to dig through the code. At least the low level stuff doesn't look that 
terrible to backport.
I wanted to look at it myself but haven't got time yet.

Would be nice to get it upstream but I don't know how it works with 
licenses and NDA.

Br,
Wojtek
