/* HISTORY
 * 18-May-90  Avadis Tevanian (avie) at NeXT
 *	Changed to use sensible priorities (higher numbers -> higher pri).
 *
 *  1-Feb-88  David Golub (dbg) at Carnegie-Mellon University
 *	Goofed... netisr thread must run at splnet, because the routines
 *	it calls expect to be called from the softnet interrupt (at
 *	splnet).
 *
 * 19-Nov-87  David Golub (dbg) at Carnegie-Mellon University
