Hello Everyone

I am currently at a project where I am using Atheros Chipsets AR9590 with the ath9k driver on Debian.
I am wondering how the time-of-flight information can be retrieved per packet in most recent Atheros chipsets.
Could you tell me how that I get that out of the driver? Or which register do I have to access in order to get the hardware timestamp (in nanosec)?

Thank you for your help!

Monika
