That is strange.       ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

You should the the master's traffic from the slave even without
ptp4l.

If there is no firewall on the slave, then I can only guess that
mellenox is doing something funny with incoming multicast frames.

Remember that tcpdump uses promiscuous mode and ptp4l uses a regular
socket.
