I'm testing this with Netronome nfp hardware. When the user > has 2 physical ports, 1 pf, and 4 vfs, he should see something like this:
J/J (Jiri/Jakub) -- re "2 physical ports, 1 pf, and 4 vfs" --- does NFP exposes one PF for both physical ports? FWIW note that in mlx5 and AFAIK any other device except for mlx4 (...) folks have FPP (Function Per Port) scheme.

What is the purpose/role in getting dev link ports here? is it such that @ the end of the day the driver would do a devlink_port_get_phys_port_name() call in their get phys port name ndo? or we buy more advantages out of doing so? Or.
