  17  *  --------  --------  ------------------------------------------------------
  18  *  04-30-07  02.00.00  Corresponds to Fusion-MPT MPI Specification Rev A.
  19  *  06-04-07  02.00.01  Bumped MPI2_HEADER_VERSION_UNIT.
  20  *  06-26-07  02.00.02  Bumped MPI2_HEADER_VERSION_UNIT.
  21  *  08-31-07  02.00.03  Bumped MPI2_HEADER_VERSION_UNIT.
  22  *                      Moved ReplyPostHostIndex register to offset 0x6C of the
  23  *                      MPI2_SYSTEM_INTERFACE_REGS and modified the define for
  24  *                      MPI2_REPLY_POST_HOST_INDEX_OFFSET.
  25  *                      Added union of request descriptors.
  26  *                      Added union of reply descriptors.
  27  *  10-31-07  02.00.04  Bumped MPI2_HEADER_VERSION_UNIT.
  28  *                      Added define for MPI2_VERSION_02_00.
  29  *                      Fixed the size of the FunctionDependent5 field in the

  31  *  12-18-07  02.00.05  Bumped MPI2_HEADER_VERSION_UNIT.
  32  *                      Removed the MPI-defined Fault Codes and extended the
  33  *                      product specific codes up to 0xEFFF.
  34  *                      Added a sixth key value for the WriteSequence register
  35  *                      and changed the flush value to 0x0.
  36  *                      Added message function codes for Diagnostic Buffer Post
  37  *                      and Diagnsotic Release.
  38  *                      New IOCStatus define: MPI2_IOCSTATUS_DIAGNOSTIC_RELEASED
  39  *                      Moved MPI2_VERSION_UNION from mpi2_ioc.h.
  40  *  02-29-08  02.00.06  Bumped MPI2_HEADER_VERSION_UNIT.

  43  *                      Added #defines for marking a reply descriptor as unused.
  44  *  06-27-08  02.00.09  Bumped MPI2_HEADER_VERSION_UNIT.
  45  *  10-02-08  02.00.10  Bumped MPI2_HEADER_VERSION_UNIT.
  46  *                      Moved LUN field defines from mpi2_init.h.
  47  *  01-19-09  02.00.11  Bumped MPI2_HEADER_VERSION_UNIT.
