Subject: [PATCH net-next v2 09/15] bnxt_en: Register devlink irrespective of firmware spec version

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

This will allow to register for devlink port and use port features.
Also register params only if firmware spec version is at least 0x10600
which will support reading/setting numbered variables in NVRAM.
