With newer versions of OVN, port bindings are removed and added
for both virtual ports and container ports (aka trunk ports in
Neutron world)[1][2].
With this, Neutron recently landed a change in order to handle
virtual ports for the update/delete steps[3], however, this has
resulted in unexpected behaviour where the binding information
is wiped for trunk ports, then subsequently removed on the
next maintenance run.
We should make sure that we only have row deletes for
virtual ports specifically rather than all ports.
