     * @description: 	In 1000BASE-T mode, the transmitted 8-bit data is scrambled into 9-bit symbols and further encoded into 4D-PAM5
     * 					symbols. On the receiving side, the idle stream is examined first. The scrambler seed, pair skew, pair order and polarity
     * 					must be resolved through the logic. The incoming 4D-PAM5 data is then converted into 9-bit symbols and de-scrambled
     * 					into 8-bit data.
