Or which register do I have to access in order to get the hardware timestamp (in nanosec)? 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.
