HW Timestamping in Intel XXV710 (25G Mode)

[PGK]

Hi,

I was performing some latency measurements with Intel XXV710 in 10G mode and HW timestamps were done for test PTP packets correctly.

However, When I switched to 25G mode using ethtoo, HW timestamps are no longer done. I am using DPDK to send PTP packets.

Please let me know if I need to enable something to enable HW timestamping in 25G mode.

Thanks,

Hi Daniel,
