* The reason why the IFDATA_LINKSPECIFIC stuff is not under the

* 2) The fourth level under net.link.<iftype> is <pf>; that is to say,
* the net.link.<iftype> tree instruments the adaptation layers between

* instruments ARP). This does not really leave room for anything else
* that needs to have a well-known number.
