From: Long Wu <long...@corigine.com>
A NFP representor port can receive a bond notification. Then driver
will parse this notification into one of these two events:
1. Bonding port configuration may have changed.
This includes creation of a bonding port, removal/addition of
a member port, changing the bond mode, etc.
2. Bonding port is deleted.
