Packet ICMPMessage

File: src/inet/networklayer/ipv4/ICMPMessage.msg

ICMP message class

Note: receiver MUST NOT decapsulate the datagram from ICMP error messages, because their contents is conceptually truncated. decapsulate() would result in a "length became negative" error; use getEncapsulatedMsg() instead.

TODO: add originator id and sequence number and create an ICMPControlInfo
