Some protocols that extend from UDP->TCP like this create a status
code or flag that indicates the question should be made via TCP.  In
those cases they simply answer the question to the extent that can be
made to fit in the reply packet...something we can't (or shouldn't)
do in DHCPv6's case.

No one should think it is reasonable to attempt these queries over UDP
and fall back to TCP.  You try TCP first and last, no 'upgrade
mechanism' is efficient here.

So since any such status code is never going to be used assuming that
implementations comply with the spec...I'd suggest just treating a
UDP query with one of these types like it was garbage.  Drop and
(maybe) log.  No reply, no new status code.
