Public bug reported:
I'm evaluating a rolling upgrade from liberty to mitaka in sr-iov
environment.
The following error occurred in resource_tracker in case controller node
is mitaka and compute node is liberty.
Error updating resources for node overcloud-compute-0.localdomain: Cannot load
'parent_addr' in the base classTraceback (most recent call last):

NotImplementedError: Cannot load 'parent_addr' in the base class
The cause of error is that a parent_addr parameter which has been added newly
since mitaka is not set correctly.
We should consider the a pci device object that nova-conductor receives
from nova-compute does not have a parent_addr attribute.
