Subject: [patch net-next v4 01/12] nfp: register devlink port before netdev

From: Jiri Pirko <jiri@...lanox.com>

Change the init/fini flow and register devlink port instance before
netdev. Now it is needed for correct behavior of phys_port_name
generation, but in general it makes sense to register devlink port
first.
