 *   2) The fourth level under net.link.<iftype> is <pf>; that is to say,
 *	the net.link.<iftype> tree instruments the adaptation layers between
 *	<iftype> and a particular protocol family (e.g., net.link.ether.inet
 *	instruments ARP).  This does not really leave room for anything else
 *	that needs to have a well-known number.
