   44  *  ---------------
   45  *
   46  *  Date      Version   Description
   47  *  --------  --------  ------------------------------------------------------
   48  *  04-30-07  02.00.00  Corresponds to Fusion-MPT MPI Specification Rev A.
   49  *  08-31-07  02.00.01  Modifications to RAID Action request and reply,
   50  *                      including the Actions and ActionData.
   51  *  02-29-08  02.00.02  Added MPI2_RAID_ACTION_ADATA_DISABL_FULL_REBUILD.
   52  *  05-21-08  02.00.03  Added MPI2_RAID_VOL_CREATION_NUM_PHYSDISKS so that
   53  *                      the PhysDisk array in MPI2_RAID_VOLUME_CREATION_STRUCT
   54  *                      can be sized by the build environment.
   55  *  07-30-09  02.00.04  Added proper define for the Use Default Settings bit of
   56  *                      VolumeCreationFlags and marked the old one as obsolete.
   57  *  05-12-10  02.00.05  Added MPI2_RAID_VOL_FLAGS_OP_MDC define.
   58  *  08-24-10  02.00.06  Added MPI2_RAID_ACTION_COMPATIBILITY_CHECK along with
   59  *                      related structures and defines.
   60  *                      Added product-specific range to RAID Action values.
   61  *  11-18-11  02.00.07  Incorporating additions for MPI v2.5.
   62  *  02-06-12  02.00.08  Added MPI2_RAID_ACTION_PHYSDISK_HIDDEN.
   63  *  07-26-12  02.00.09  Added ElapsedSeconds field to MPI2_RAID_VOL_INDICATOR.
   64  *                      Added MPI2_RAID_VOL_FLAGS_ELAPSED_SECONDS_VALID define.
   65  *  04-17-13  02.00.10  Added MPI25_RAID_ACTION_ADATA_ALLOW_PI.
   66  *  11-18-14  02.00.11  Updated copyright information.
