[DNA] Updates to dna-protocol3

[Brett Pentland <brett.pentland@eng.monash.edu.au>]

Before submitting the draft to become draft-ietf-dna-protocol-00.txt I
have some updates to reflect the feedback that we've had so far.  The
update can be viewed at:

http://www.ctie.monash.edu.au/dna-dt/draft-ietf-dna-protocol-pre00.txt

And a diff from protocol3 can be seen at:

Does anyone have any objections to the amendments made so far?  Do they
break anything?  Positive ACKs are ok too. :)

There's a few issues that have come up while making the edits.  They
don't necessarily have to be resolved before submission of the -00, but
some input would be useful.

- Should the explicit linkid always be in the LPO or can it be a flag in
   a PIO (the latter is in the draft)?

- What order do the hosts treat the indications (land mark option,
   prefixes, linkid in the draft at present)

- Given that we now have an explicit linkid, should we get rid of all of
   the flags in the landmark option - the no flag is not really needed
   and since taking that out would leave only one, we can probably get
   rid of that as well - LO in RA = yes (at present the flags are still
   there)

Regards,
Brett.
