Give Feedback Byte Deserializer Disabled Mode

In disabled mode, the byte deserializer is bypassed. The data from the 8B/10B decoder, rate match FIFO, or word aligner is directly transmitted to the RX PCS FIFO, depending on whether or not the 8B/10B decoder and rate match FIFO are enabled. Disabled mode is used in low-speed applications such as GigE, where the FPGA fabric and the PCS can operate at the same clock rate.
