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.

Subject: [E1000-devel] timestamp timeout with E810

Hi,

I am using linuxptp with an Intel E810-XXV Ethernet controller with ice driver 
version 1.5.8. 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.

Regards,
Sean
