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.
