69 *                      MPI2_REPLY_POST_HOST_INDEX_OFFSET.
70 *                      Added union of request descriptors.
71 *                      Added union of reply descriptors.
72 *  10-31-07  02.00.04  Bumped MPI2_HEADER_VERSION_UNIT.
73 *                      Added define for MPI2_VERSION_02_00.
74 *                      Fixed the size of the FunctionDependent5 field in the
75 *                      MPI2_DEFAULT_REPLY structure.
76 *  12-18-07  02.00.05  Bumped MPI2_HEADER_VERSION_UNIT.
77 *                      Removed the MPI-defined Fault Codes and extended the
78 *                      product specific codes up to 0xEFFF.
79 *                      Added a sixth key value for the WriteSequence register
80 *                      and changed the flush value to 0x0.
81 *                      Added message function codes for Diagnostic Buffer Post
82 *                      and Diagnsotic Release.
83 *                      New IOCStatus define: MPI2_IOCSTATUS_DIAGNOSTIC_RELEASED
84 *                      Moved MPI2_VERSION_UNION from mpi2_ioc.h.
85 *  02-29-08  02.00.06  Bumped MPI2_HEADER_VERSION_UNIT.
