The fact that if_loop can't be unloaded is the result of layering
violations that it would be nice to get rid of some day.  It may or not
be practical, but it would be nice.  I did a full cloning implementation
in if_loop because it's a better example of how to build a network
pseudo device then if_disc because it's closer to fully functional.
