I like this idea.

We could add an icmp preference item to let the user disable that heuristic and
to display both the big and little endian representations.  It may be worth
"overloading" the display filter field for both the little and big endian
representations so the user doesn't have to think of which to type in, similar
to how I did that with the TCP window size recently (assigning the value from
the packet and the optional scaled window size as the same display filter).
