This make the l3_dvrscheduler_db subscribe the port_update event. Even though I don't use DVR, this notification do nothing but many checks in this notification handler waste the time. The large allowed-address-pair requirement is used in Kubernetes integration with Neutron when container use macvlan mode in VM.
