Public bug reported:

The server logs are filled with the warnings below in a normal tempest
run. This is easy to trigger in a normal workflow by updating a port
which is not yet bound to a host. For example, the following will result
in a warning:

neutron port-create net --name=myport
neutron port-update myport --allowed-address-pairs type=dict list=true mac_address=01:02:03:04:05:06,ip_address=1.1.1.1/32
