Abstract:

   The ICMP Extension Structure (RFC4884) does not have a length field.
   Therefore, unless the length of the Extension Structure can be
   inferred from other data in the ICMP message, the Extension Structure
   must be the last item in the ICMP message.

   This document updates RFC 4884 to define a length field for the ICMP
   Extension Structure.  When length information is provided, receivers
   can use it to parse ICMP messages.  Specifically, receivers can use
   length information to determine the offset at which the item after
   the ICMP Extension Structure begins.
