Folks, here is a new draft version that covers some of the questions that arose from
the previous. This version further builds out on the concept of Path MTU Discovery
Soft Errors and seeks to update several RFCs as a result.

Apologies in advance if I have missed anything, and I will try to address them in the
next document version.

Comments?

Fred

        Title           : IPv6 Fragment Retransmission and Path MTU Discovery Soft Errors

Abstract:
   Internet Protocol version 6 (IPv6) provides a fragmentation and
   reassembly service for end systems allowing for the transmission of
   packets that exceed the path MTU.  However, loss of just a single
   fragment requires retransmission of the original packet in its
   entirety, with potentially devastating effects on performance.  This
   document specifies an IPv6 fragment retransmission scheme that
   matches the loss unit to the retransmission unit.  The document
   further specifies an update to Path MTU Discovery that distinguishes
   hard link size restrictions from reassembly congestion events.
