Thanks for all the responses!

No - I hadn't been able to test that due to a firewall issue. But I
just tested and UDPv4 also fails in the same way.

That would be cool. I will follow up with Intel to check (and Jake has
now replied too).

Thanks! I was also planning to file an IPS ticket, should I still do that?

Just built linuxptp from HEAD. I assume any ptp4l that sets version
2.1 (constant is in msg.h) would have the same failure.

On one side I ran:

sudo /tmp/ptp4l -m -4 -i eth0 -q

On the other I ran:

sudo /tmp/ptp4l -m -4 -i eth0 -q -s

Both sides will report errors -- one will report RX timestamp failures
on Sync, and the other on DelayReq. Like this:

ptp4l[25253.624]: port 1 (eth0): received SYNC without timestamp

firmware-version: 5.10 0x800025e4 0.0.0
