It's really a matter of time. We didn't anticipate limited broadcast being broken in FreeBSD and we're scrambling to come up with a solution. To be quite frank I haven't done anything with IPv6 before so it would be more research to get up to speed on this option. It seems our best option is scapy, which unfortunately I also haven't used before...
