        Folks sending anything larger than IEEE standard frame sizes
on any Ethernet need to be sure to re-configure all the equipment
accordingly and test the whole subnet out thoroughly.  For now, 
there seems to be no substitute for that (and yes, it is 
a fair bit of work).  As near as I can tell, all switches ship
with IEEE-standard MTU as the default, so require manual operator
reconfiguration to support any larger frame size.
