Do you mean: ?
hscb->cdb_len = cmd->cmd_len;
if (hscb->cdb_len <= 12) {
memcpy(hscb->shared_data.cdb, cmd->cmnd, hscb->cdb_len);
} else {
memcpy(hscb->cdb32, cmd->cmnd, hscb->cdb_len);
scb->flags |= SCB_CDB32_PTR;
}

Isn't there a way to determine if the HBA has an hardware limitation, or the
size of the max command length it accepts?
