    [DVR] Set arp entries only for IPs from the correct subnet
    
    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.

Title:
  [DVR] ARP entries for allowed address pairs with IPv4 addresses are
  added using qr- interface from IPv6 subnets

Status in neutron:
  Fix Released

Bug description:
  ARP entries for allowed address pairs are added in the DVR routers
  also for IPv6 subnets even if IP is IPv4 address really.
