 *   Facility:	Systems Communication Architecture
 *		Computer Interconnect Port-to-Port Driver
 *
 *   Abstract:	This module contains Computer Interconnect Port-to-Port
 *		Driver( CI PPD ) data structure definitions visible to SYSAPs.
 *
 *   Creator:	Todd M. Katz	Creation Date:	July 31, 1987
 *
 *   Modification History:
 *
 *   08-Jan-1989	Todd M. Katz		TMK0002
 *	Remove the bit map ptdlogmap from the CIPPDLPIB.
 *
 *   08-Jan-1988	Todd M. Katz		TMK0001
 *	Formated module, revised comments, increased robustness, made CI
 *	PPD and GVP completely independent from underlying port drivers, and
 *	added SMP support.
