The interface is configured to receive the addresses, however Ubuntu
does that.  This is a separate test VM without dhcpcd.  And SLAAC works
with a "route" section in radvd.conf along with the "prefix" (or maybe
it just takes a while to apply).  But DHCPv6 is still giving /128
addresses in both cases.

So I'm still mystified in that both implementations think there's
something wrong, but I don't know what it is.

Indeed, and we find it useful to use it like that to control all dynamic
address and route assignment.  And it makes this all the more
perplexing, because if dhcpcd can use the prefix length to assign a
stateless address, why not use the same prefix length for the DHCPv6
address?  It wouldn't attempt to get the address at all if it hadn't
received the correct advertisement.

In that case, I know what the 3rd party is, so never mind this detail.
