This is one piece of the grand unified PPP daemon concept, whereby using netgraph nodes enables PPP data to be handled completely in kernel land, while leaving negotiation/control to be handled by a single user land daemon, no matter what the link type(s). This is a safety checkin only; it compiles, but is utterly untested. Concept reviewed by: julian, brian
