 *   Facility:	Systems Communication Architecture
 *		Computer Interconnect Port Driver
 *
 *   Abstract:	This module contains Computer Interconnect Port Driver( CI )
 *		constants, data structure definitions, and macros required
 *		to link CI ports and their driver with lower level machine
 *		specific portions of the Ultrix kernel.
 *
 *   Creator:	Todd M. Katz	Creation Date:	January 31, 1986
 *
 *   History:
 *
 *   Modification History:
 *
 *   06-Jun-1990	Pete Keilty
 *	1. Added preliminary support for CIKMF( dash ).
 *	2. Added new structure CIISR.
 *
 *   19-Sep-1989	Pete Keilty
 *	Change XCB to XCD.
 *
 *   27-Apr-1988	Todd M. Katz
 *	1. Add support for the CIXCB hardware port type by adding support for
 *	   XMI based ports to structure definition CIADAP through addition of
 *	   structure xmi to union ic and the creation of shorthand notations
 *	   Xminum and Xminode.
 *	2. Add the CIBCA BIIC Device Type Register Port Revision Field Mask
 *	   Bits constants.
 *
 *   08-Dec-1987	Todd M. Katz
 *	Formated module, revised comments, and generalized CIADAP
 *	definition to support multiple interconnect types.
