               uint64_t               PtrReply;
               uint64_t               PtrData;
               uint32_t               RequestSize;
               uint32_t               ReplySize;

               uint32_t               DataOutSize;
               uint32_t               Timeout;
} mps_pass_thru_t, * ptrmpssas_pass_thru_t;

In the above mps_pass_thru structure; Application expects PrtReply buffer
should contain both MPI reply followed by sense data. So, updated driver
to copy sense data at PtrReply + sizeof(MPI2 reply) location where
application wants the driver to copy back the sense data info.
