Title:
  Link Local Address should be allowed to be set as router interface for
  IPv6 subnet

Status in neutron:
  Expired

Bug description:
  Although Link Local address is allowed to be set as the gateway IP
  address of an IPv6 subnet when force_gateway_on_subnet is set to
  False, the following error will occur when attach the subnet to a
  neutron router:

  neutron router-interface-add e911e39a-45e1-437f-bc5c-7c22b8c408d5 test_ipv6_subnet
  400-{u'NeutronError': {u'message': u'Invalid input for operation: IP address fe80::2001:1 is not a valid IP for the defined subnet.', u'type': u'InvalidInput', u'detail': u''}}

  
  This is because there is step to check if the gateway IP is inside the subnet when attaching the subnet to the router. This works for IPv4 but not IPv6 because IPv6 uses Link Local address ONLY to send RA.
