I could not find any advice in RFC3315 as to what to set the IPv6
HOP Limit to for multicast'ed DHCPv6 messages.

I would have thought that the sender should set it to 255, and the
sender should validate that it is 255, to be sure that it's onlink.
This is what mDNS/Bonjour does, but maybe 3315 predates that thinking.

Should 3315bis say something different?
(Clearly, it has to be backwards compatible for awhile)
