This memo defines a data structure that can be appended to selected
ICMP messages.  The ICMP extension defined herein can be used to
identify any combination of the following: the IP interface upon
which a datagram arrived, the sub-IP component of an IP interface
upon which a datagram arrived, the IP interface through which the
datagram would have been forwarded had it been forwardable, and the
IP next hop to which the datagram would have been forwarded.

Devices can use this ICMP extension to identify interfaces and their
components by any combination of the following: ifIndex, IPv4
address, IPv6 address, name, and MTU.  ICMP-aware devices can use
these extensions to identify both numbered and unnumbered interfaces.
