Hi Seán, The 1 ms default timeout is small and we are working with the ptp4l community to increase it. Saying that we know that we have currently some limitations on the E810 family. With the next major release of the FW and the driver the tx_timestamp_timeout value will be reduced to smaller and will meet the updated default timeout.

Do you know where that doc is available?

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.
