timestamps with af_xdp

Sorry to bother, but I can't find it anywhere in the documentation. Does onload use hardware timestamps when in af_xdp mode?

The recently merged https://github.com/Xilinx-CNS/onload/pull/167 introduces HW timestamps for AF_XDP. However, the underlying network driver must implement the xmo_rx_timestamp() function, which implies the use of newer Linux kernels. Hope that gives you some useful pointers.

AF_XDP is not commercially supported in Onload, so there is only limited coverage in the documentation.

Do you maybe know what exactly is minimum required kernel version?

I'm told v6.3 is the kernel that introduces the required functionality.

Thanks a lot!
