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. -- Brooks --=20 Any statement of the form "X is the one, true Y" is FALSE.
