Sorry I haven't answered this more quickly. It's generated some internal discussion that is still ongoing. I think there is a doc somewhere that says you may have to increase the timeout, but that's also under discussion.

Regular timeouts are occurring when retrieving the TX timestamp: ptp4l[4756.840]: timed out while polling for tx timestamp ptp4l[4756.840]: increasing tx_timestamp_timeout may correct this issue, but it is likely caused by a driver bug ptp4l[4756.840]: port 1 (p2p1): send sync failed ptp4l[4756.840]: port 1 (p2p1): MASTER to FAULTY on FAULT_DETECTED (FT_UNSPECIFIED) Increasing the linuxptp tx_timestamp_timeout setting to 50ms (from a default of 1ms) stops the timeouts. Is such a large delay expected with the E810/ice driver? I have previously being using an Intel XXV710 with i40e driver and never saw this error using the default timeout value of 1ms.
