Public bug reported:

Allowed_address_pair fixed_ip when configured with FloatingIP after the
port is associated with the VM port is not reachable from DVR router.

The current code only supports adding in the proper ARP update and port
host binding inheritence for the Allowed_address_pair port only if the
port has a FloatingIP configured before it is associated with a VM port.

When the floatingIP is added later,  it fails.

How to reproduce.

1. Create networks
2. Create vrrp-net.
3. Create vrrp-subnet.
4. Create a DVR router.
5. Attach the vrrp-subnet to the router.
6. Create a VM on the vrrp-subnet
7. Create a VRRP port.
8. Attach the VRRP port with the VM.
9. Now assign a FloatingIP to the VRRP port.
10. Now check the ARP table entry in the router_namespace and also the VRRP port details. The VRRP port is still unbound and so the DVR cannot handle unbound ports.
