 *
 * The document at

 *	http://www.watersprings.org/pub/id/draft-ietf-rmonmib-rmonprot-v2-00.txt
 *
 * lists a bunch of values of protocol identifier fields for various
 * protocols.  It speaks of the Vines Fragmentation Protocol,
 * the "Vines Token Ring Protocol" which appears to be the same as the
 * "Vines LLC" protocol here, the Vines echo protocol, Vines IP, and
 * protocols running atop Vines IP.
 *
 * The LLC values it describes are:
 *
 *	0xbc	(SAP_VINES2) Vines Token Ring a/k/a Vines LLC
 *
 * It doesn't mention 0xba (SAP_VINES1).
 *
 * The Vines Token Ring/Vines LLC protocol identifier values it
 * describes are:
 *
 *	0xba	Vines IP
 *	0xbb	Vines Echo
 *
 * The Ethernet type values it describes are:
 *
 *	0x0bad	(ETHERTYPE_VINES) Vines IP
 *	0x0baf	Vines Echo
