Public bug reported:

Description
===========

Neutron support update port to add or modify fixed ip.
Nova support consuming vif_updated_event from Neutron.
However, this event isn't notified for vif driver, so network info data 
in nova compute and local network agent state may be inconsistent.


Steps to reproduce
==================

1. Create Port in neutron
2. Create VM in nova
3. Update port


Expected result
===============

vif_driver can consume vif_updated_event


Actual result
=============

There is no way to consume vif updated event.

Environment
===========

We have confirmed this issue environment for OpenContrail driver.
