[Linuxptp-users] Issue: received SYNC without timestamp

[Saurav K. <s.k...@si...>]

Hi All,

I have been facing "received SYNC without timestamp" issue whlie running
PTP slave. I have also attached output of cat
/sys/kernel/debug/tracing/trace_pipe | grep -C3 i40e
in trace_pipe_i40e.txt

We are using Intel XXV710 series ethernet controller.

Following are the information of PTP slave machine.
Please let me know if you need anything.
