[PATCH v6 02/14] ethdev: add API to get firmware creation of bonding port

[Chaoyong He <chaoyong.he@corigine.com>]

From: Long Wu <long.wu@corigine.com>

After bonding port notification, member port firmware may create the
bonding port. We want to get the result of creatition, so we add this
API to do the getting action.
