- * Scramble an input stream using an LFSR. This block works on the LSB only
- * of the input data stream, i.e., on an "unpacked binary" stream, and
- * produces the same format on its output.
- *
- * \param mask Polynomial mask for LFSR
- * \param seed Initial shift register contents
- * \param len Shift register length
- * \param count Number of bits after which shift register is reset, 0=never
- *
- * The scrambler works by XORing the incoming bit stream by the output of
- * the LFSR. Optionally, after 'count' bits have been processed, the shift
- * register is reset to the seed value. This allows processing fixed length
- * vectors of samples.
