Maybe the use case can be understood before reverting the change. How do
we actually the physical port number of an Ethernet switch per-port
network device? The name is not enough, because there are plenty of
cases where we need to manipulate a physical port number (be it just for
informational purposes).

Should we just amend the existing description of ndo_get_phys_port_id()?
Should we introduce another ndo for that?
