Public bug reported:

Currently neutron l3 router will run radvd to send out RA packets about
the ManagedFlag, LinkMTU and prefix of IPv6 subnet. But rememeber we
have a distributed SDN controller, aka ovs-agent, which can do this work
more naturally and gracefully.

Current radvd config looks like this:

interface qr-8fd65326-c4
{
   AdvSendAdvert on;
   MinRtrAdvInterval 30;
   MaxRtrAdvInterval 100;
   AdvLinkMTU 1500;
   AdvManagedFlag on;
   prefix fda7:a5cc:3460:3::/64
   {
        AdvOnLink on;
        AdvAutonomous off;
   };
};

While RYU supports  Router Advertisement:
https://ryu.readthedocs.io/en/latest/library_packet_ref/packet_icmpv6.html#ryu.lib.packet.icmpv6.nd_router_advert

This can narrow down the burden of L3-agent management and run less
process for a router.
