Public bug reported:

Ports are removed from the br-int, but the ovs-agent resource_cache
still have them. If during this removal period, the port attributes
changed/updated. Even worse if the update event is not received by the
agent, as well as the port plug to the br-int again. The ovs-agent will
use the obsolete resource informaction of the port. Something may not be
processed well then.
