Are you sure that by multiple ports you do not mean multiple SerDes
lanes? Otherwise, I do not understand what you are referring to.

The dpaa2-eth driver will register one netdev for each DPNI object
(network interface) and will control/configure one DPMAC (MAC).
There is a 1-1 relationship between these two.
