When dvr router is processing internal ports it is checking all ports connected to the subnet and adding permanent arp entries for all fixed IPs and allowed address pairs from those ports in the qrouter namespace. But port can have fixed IPs from different subnets, e.g. from IPv4 and IPv6 subnet and until now Neutron wasn't checking subnet_id of the fixed_ip address nor ip version of the allowed address pair's IP address. That resulted in adding arp entries for all IPs through all interfaces, e.g. IPv4 address was added as it's reachable through interface connected to the IPv6 subnet. This patch adds checking of the subnet_id for fixed_ips and ip version for the allowed address pairs configured on the port to avoid that problem. Closes-Bug: #1936980 Change-Id: Id5afad7af74d69f8b4159163d23807a1cf032733
