Public bug reported:

At line 2484 of
https://github.com/openstack/nova/blob/master/nova/network/neutronv2/api.py
the code is accessing  p[‘id’]  in the LOG.info block,  but that means
it logs the last entry that it iterated over in the previous loop over
the ports rather than the port_id being processed in the current loop.

We see this when we have multiple ports, it suggests it is updating the
same port over and over, when its actually working properly
