[PATCH net-next 0/2] dpaa2-eth: devlink port number from the DPMAC

dpaa2-eth registers every DPNI as a physical devlink port without a
port number, so all the DPAA2 interfaces report the same
phys_port_name "p0", including the DPNIs that have no DPMAC behind
them.

Patch 1 uses the DPMAC id as the physical port number. The attributes
of a registered devlink port cannot change, so when the DPNI endpoint
changes at runtime a warning says the number is stale until the DPNI
is rebound.

Patch 2 registers the DPNIs without a DPMAC as virtual ports. They
have no phys_port_name, so "p<dpmac id>" is unique.

With both patches, udev can name an interface using its DPMAC, for
instance:

  SUBSYSTEM=="net", ACTION=="add", DRIVERS=="fsl_dpaa2_eth", \
    ATTR{phys_port_name}=="p3", NAME="dpmac3"
