Before that patch it was possible to send ICMPv6 packets like e.g.
neutron_lib.constants.ICMPV6_TYPE_MLD_QUERY,
neutron_lib.constants.ICMPV6_TYPE_RS,
neutron_lib.constants.ICMPV6_TYPE_NS,
neutron_lib.constants.ICMPV6_TYPE_NA
And that could cause some security issues as instance could advertise
that it owns IPv6 address which really don't belong to it.
Now rules in table=71 which allows that traffic are "per mac/ipaddress"
and are allowed only for fixed ips allocated to port and port's
allowed_address_pairs.
