Title:
  IPv6 Router Advertisements are blocked in secgroups when using radvd
  based networks

Status in OpenStack Neutron (virtual network service):
  Fix Released
Status in neutron juno series:
  Fix Committed

Bug description:
  Description of problem:
  =======================
  Discovered in: https://bugzilla.redhat.com/show_bug.cgi?id=1173987

  I Created n radvd IPv6 subnet with:
  1. ipv6_ra_mode: dhcpv6-stateless
  2. ipv6_address_mode: dhcpv6-stateless

  Version-Release number of selected component (if applicable):
  =============================================================
  openstack-neutron-2014.2.1-2

  How reproducible:
  =================
  100%

  Steps to Reproduce:
  ===================
  1. Create an IPv4 neutron network (might not be mandatory but this is how I did it):
     # neutron net-create internal_ipv4_a --shared

  2. Create an IPv4 subnet:
     # neutron subnet-create <IPv4_net_id> 192.168.1.0/24 --name internal_ipv4_a_subnet --ip-version 4

  3. Create an IPv6 neutron network:
     # neutron net-create tenant_a_radvd_stateless --shared --provider:network_type=gre --provider:segmentation_id=123

  4. Create an IPv6 subnet:
     # neutron subnet-create <IPv6_net_id> 2001:1234:1234::/64 --name internal_ipv6_subnet --ipv6-ra-mode dhcpv6-stateless --ipv6-address-mode dhcpv6-stateless --dns-nameserver 2001:4860:4860::8888 --ip-version 6

  5. Create a neutron router:
     # neutron router-create router1

  6. Attach subnets to the router
     # neutron router-interface-add <router_id> <ipv4_subnet>
     # neutron router-interface-add <router_id> <ipv6_subnet>

  7. boot an instance with that network
     # nova boot tenant_a_instance_radvd_stateless --flavor m1.small --image <image_id> --key-name keypair --security-groups default --nic net-id=<ipv4_net_id> --nic net-id=<ipv6_net_id>

  Actual results:
  ===============
  1. RAs reach the instance qbr but not to the instance tap device.
  2. Instance did not obtain IPv6 address.

  Expected results:
  =================
  IPv6 Router Advertisements should reach the instance.

  Additional info:
  ================
  1. Compute node and L3 agent deployed on different servers.
  2. Communication between the nodes (RAs) done via GRE tunnels.
  3. This worked before openstack-neutron-2014.2-11
  4. Tested with RHEL7
