Subject: [PATCH net-next 3/3] bnxt_en: fix switchdev port naming for external-port-rep and vf-reps

Fix the phys_port_name for the external physical port to be in
"pA" format and that of VF-rep to be in "pCvfD" format as
suggested by Jakub Kicinski.

Fixes: c124a62ff2dd ("bnxt_en: add support for port_attr_get and get_phys_port_name")
