* 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.
