Comment from Daniel for improving Section 8.1.3:
Daniel: I was reading the RPL spec and noticed they reference RFC 1982 to
explain the serial arithmetic that is used for version number calculation.
The RFC contains a very clear explanation including the corner cases. A
reference to RFC 1982 instead of TCP would make the ND draft clearer and
the last paragraph of section 8.1.3 could be removed.
Erik: The only difference is for the case when the old and new differ by
half the space (0x80000000) in which case I put some explicit words in the
last para, and RFC 1982 says that the result of the comparison is
undefined. I think we can handle that while referring to RFC 1982 by
saying "if the version number received in the packet is greater than the
stored version number (following RFC 1982 section x-y)" which would be
well-defined for all cases.
