There is an issue with the hardware on the B410P that makes it unreliable to
connect one of the ports to another port for testing.

# NOTE: The B410P card cannot reliably connect one of its four ports
# configured in TE mode to another one configured in NT mode. It will not
# reliably sync clock from itself. Please use another physical card and
# configure one to provide clock and one to recover clock in any B410P test
# environments.
