[openstack-dev] ipv6 and ipv4 dual stack for floating IP

I'm seeing the same error when trying to setup a whole new network
through Horizon with external gateway and an ipv4 and ipv6 subnet. Eg,
without floating ip.
l3_agent.py is trying this: prefixlen =
netaddr.IPNetwork(port['subnet']['cidr']).prefixlen
Looking inside port[] lists the following items:

_set_subnet_info() is set to log an ERROR when it encounters multiple
addresses and then happily continues doing something:
prefixlen = netaddr.IPNetwork(port['subnet']['cidr']).prefixlen
port['ip_cidr'] = "%s/%s" % (ips[0]['ip_address'], prefixlen)
Operations with just 1 (ipv6) ip go without any issues, the adress is
added to a namespace and pongs just fine. Adding 2 subnets to this
external net and creating a gateway to it on the l3 router causes a problem.
Do we need to wait for K before we can fully go dual-stack?
