Bug Description
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-
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.

Can you post your result of "ip6tables --list" on your compute host?
For provider network, can you check if the gateway specified for subnet is the link local address of the provider router interface?
For RADVD, can you also post the link local address of the "qr-XXXX" device in router namespace of L3 agent node?
