The Point-to-Point Protocol (PPP) defines a Link Control Protocol
(LCP) and a method for negotiating the use of multi-protocol traffic
over point-to-point links. PPP Vendor Extensions (RFC 2153) added
vendor-specific general-purpose Configuration Option and Code numbers.
This document extends these features to cover vendor-specific Network,
Authentication, and Control Protocols.
