4. When a rest query done on ODL: Policy deleted from ODL but still the policy remains bound to the Port in ODL
Ideally ODL should delete the policy whenever Neutron deletes it. There should not be any inconsistencies between Openstack and ODL databases. I think there should be a bug in the ML2 driver code. If not please assign to the right module.

ODL deletes QOS policy bound to a port inspiteof Neutron rejecting the policy delete since its associate to a port.
