 *   Facility:	Systems Communication Architecture
 *		Computer Interconnect Port Driver
 *
 *   Abstract:	This module contains Computer Interconnect Port Driver( CI )
 *		constants and data structure definitions visible to SYSAPs.
 *
 *   Creator:	Todd M. Katz	Creation Date:	April 22, 1985
 *
 *   Modification History:
 *
 *   19-Sep-1989	Pete Keilty
 *	Added CI port info. port_fcn_ext2.
 *
 *   18-Jan-1989	Todd M. Katz		TMK0003
 *	Add padding when it is necessary to keep longword alignment.  While
 *	some space is wasted such alignment is essential for ports of SCA to
 *	hardware platforms which require field alignment and access type to
 *	match( ie- only longword aligned entities may be longword accessed ).
 *
 *   03-May-1988	Todd M. Katz		TMK0002
 *	Rename ram_level -> fn_level within structure ucode_rev of the CIPIB.
 *
 *   08-Jan-1988	Todd M. Katz		TMK0001
 *	Formated module, revised comments, increased generality and
 *	robustness, made CI PPD and GVP completely independent from underlying
 *	port drivers, and added SMP support.
