[manet] DLEP Latency Range Extension

[Justin Dean <[e-mail]>]

The document has been submitted to the IESG for publication.

I do have one nit which can be taken care of in future revisions.  The
range min/maxim is stated in the abstract in a overly fuzzy way.  The
packets may experience that delay....but they may not?  The definition of
the Maximum Latency and Minimum Latency in section 3 appear to prohibit
this, and the range is an absolute range, not a best effort guess for 99%
of the packets to be within the specified range.

Suggested fix to the abstract. s/may/can

Suggested fix to section 3  (but for both max and min)

A 64-bit unsigned integer, representing the longest transmission
      delay, in microseconds, that a packet encounters as it is
      transmitted over the link.
