 * This block is the opposite of u482c_encode. It performs frame encoding for
 * the legacy U482C and some modes of the AX100. Input/output is PDUs.  The main
 * characteristic of the frame format implemented by this block is a 24-bit
 * header that is Golay (24, 12) encoded and contains the length of the payload
 * and some flags about the encoding.
