Heh, on one of my systems, I often using a dozen bpf devices or more
(rarp and dhcp servers listening on several VLANs, plus I occasionaly
want to use tcpdump on said machine).

A different cloning mechanism would apply to ppp.  I haven't made
ppp use ifnet cloning yet, because I'm not entirely satisfied with
how a ppp unit number is chosen when you bind a serial device to a
ppp interface.

And, yes, one of the goals of this cloning code is to implement Unix98
