dpaa2-eth registers every DPNI as a devlink port of flavour physical
without setting a port number. All DPAA2 interfaces report the same
phys_port_name, p0 (see devlink port show).
The DPNI endpoint can change at runtime while the attributes of a
registered devlink port cannot, so log a warning when it happens.
Another benefit: udev rules can match ATTR{phys_port_name} to name an
interface based on its DPMAC.
