I've checked in my ISL dissector, and the changes to the Ethernet
dissector to recognize the range of multicast addresses the ISL spec
says are used (01-00-0C-00-00-XX, as I remember).

I don't know whether ISL is used on FDDI or Token Ring (i.e., whether
ISL frames are sent over FDDI or Token Ring, not whether FDDI or Token
Ring frames are sent over ISL), but, if so (which is presumably the
case), similar stuff should be done to their dissectors.

I also haven't seen any FDDI-over-ISL or Token Ring-over-ISL captures,
so I've no way to figure out what some of the less-than-clear parts of
the ISL spec mean.
