507 * On such standards, up to 8 groups of statistics can be provided, one
508 * for each carrier group (called "layer" on ISDB).
509 * In order to be consistent with other delivery systems, the first

511 * dtv_status:scale should use the value FE_SCALE_NOT_AVAILABLE when
512 * the value for the entire group of carriers or from one specific layer
513 * is not provided by the hardware.
514 * st.len should be filled with the latest filled status + 1.

519 * u.st.stat.value[1] = layer A statistics;
