In particular, the GPCMD_SET_STREAMING was being rejected at the host level in some instances. The reason is that libata-scsi insists upon the cmd_len field exactly matching the SCSI opcode being issued, whereas ide-scsi tolerates 12-byte commands contained within a 16-byte (cmd_len) CDB. There doesn't seem to be a good reason for us to not be compatible there, so here is a patch to fix libata-scsi to permit SCSI opcodes so long as they fit within whatever size CDB is provided.
