[manet] SMF IPv4 DPD and wrapping the ip_id field

["Templin, Fred L" <[e-mail]>]

John Heffner's document on "IPv4 Reassembly Errors at High Data
Rates" talks about implications of wrapping the 'ip_id' field. The
document is now in the RFC Editor queue. Below is the abstract and
link to the draft:

Abstract

   IPv4 fragmentation is not sufficiently robust for use under some
   conditions in today's Internet.  At high data rates, the 16-bit IP
   identification field is not large enough to prevent frequent
   incorrectly assembled IP fragments, and the TCP and UDP checksums are
   insufficient to prevent the resulting corrupted datagrams from being
   delivered to higher protocol layers.  This note describes some easily
   reproduced experiments demonstrating the problem, and discusses some
   of the operational implications of these observations.
