IPv6 Neighbor Solicitation partially works
Virtual switches drop IPv6 packets from linklocal source address.
FreeBSD uses linklocal source address while doing neighbor solicitation, unlike Linux and Windows which both use the global address.
The following openflow rule solves this issue:
priority=<priority>,
icmp6,
in_port=<port_id>,
dl_src=<source mac>,
ipv6_src=fe80::/64,
icmp_type=136, # Neighbor Advertisement
nd_target=<target ip>,
actions=NORMAL-
