Public bug reported:

Description of problem:
=======================
Router Advertisments are blocked and can't reach instances.
As a direct result of that, All Ipv6 networking won't function for instances.
This was tested both with provider Ipv6 router and radvd.
	 
Version-Release number of selected component (if applicable):
=============================================================
openstack-neutron-2014.2-0.7.b3

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

Steps to Reproduce:
===================
1. Create Neutron network

2. Create Neutron IPv6 subnet, don't foreget to speficy:
   a. --ipv6-address-mode
   b. --ipv6_ra_mode
   c. --gateway , in case you create this subnet for provider router. speficy the IPv6 link local address.

3. Spawn an instance

4. Check if the instance obtained IPv6 address and defeault gw. (not
expected to work)

5. Use tcpdump to see if Router Advertisments reach the instance.

6. Add a rule to allow all ICMP from fe80::/4

7. Repeat steps 4 & 5, it should work ok now.

Actual results:
===============
Router Advertisments are blocked and can't reach instances.

Expected results:
=================
Router Advertisments should be allowed by default.
