Public bug reported:

When running an instance on a network with ipv6-address-mode
dhcpv6-stateful, the instance fails to receive responses from the DHCP
server. The workaround is to add an explicit security group rule
allowing

--proto udp --dst-port 546 --ethertype IPv6

and then the DHCP handshake succeeds successfully.

See https://review.openstack.org/#/c/386525/ and the failures at e.g.
http://logs.openstack.org/25/386525/8/check/gate-tempest-dsvm-neutron-
full-ssh/b4c7bf0/, the same setup worked fine in December, so this seems
to be a regression introduced since then.
