From: Vasundhara Volam <vasundhara-v.volam@broadcom.com>

[ Upstream commit cda2cab0771183932d6ba73c5ac63bb63decdadf ]

Latest kernels get the phys_port_name via devlink, if
ndo_get_phys_port_name is not defined. To provide the phys_port_name
correctly, register devlink before registering netdev.

Also call devlink_port_type_eth_set() after registering netdev as
devlink port updates the netdev structure and notifies user.
