The 2 cases that I think this message should cover are:
1) The message length in the ISAKMP header accurately reflects the total
size of the received packet, but the sum of the individual payload lengths
(in the Generic Payload Headers) does not match the total message length.
(This often happens when a packet does not decrypt properly - IV problems,
etc.)
2) The message length in the ISAKMP header does not match the size of the
received packet.
