 *  Version History
 *  ---------------
 *
 *  Date      Version   Description
 *  --------  --------  ------------------------------------------------------
 *  04-30-07  02.00.00  Corresponds to Fusion-MPT MPI Specification Rev A.
 *  08-31-07  02.00.01  Added Command Buffer Data Location Address Space bits to
 *                      BufferPostFlags field of CommandBufferPostBase Request.
 *  02-29-08  02.00.02  Modified various names to make them 32-character unique.
 *  10-02-08  02.00.03  Removed NextCmdBufferOffset from
 *                      MPI2_TARGET_CMD_BUF_POST_BASE_REQUEST.
 *                      Target Status Send Request only takes a single SGE for
 *                      response data.
 *  02-10-10  02.00.04  Added comment to MPI2_TARGET_SSP_RSP_IU structure.
 *  11-18-11  02.00.05  Incorporating additions for MPI v2.5.
 *  11-27-12  02.00.06  Added InitiatorDevHandle field to MPI2_TARGET_MODE_ABORT
 *                      request message structure.
 *                      Added AbortType MPI2_TARGET_MODE_ABORT_DEVHANDLE and
 *                      MPI2_TARGET_MODE_ABORT_ALL_COMMANDS.
 *  06-13-14  02.00.07  Added MinMSIxIndex and MaxMSIxIndex fields to
 *                      MPI2_TARGET_CMD_BUF_POST_BASE_REQUEST.
 *  11-18-14  02.00.08  Updated copyright information.
 *  03-16-15  02.00.09  Updated for MPI v2.6.
 *                      Added MPI26_TARGET_ASSIST_IOFLAGS_ESCAPE_PASSTHROUGH.
