Asserted when the RX channel is ready to receive data. Because the
readyLatency on this Avalon-ST interface is 0, the PCS may drive
xgmii_rx_dc_valid as soon as rx_ready is asserted.
This clock is generated by the same reference clock that is used to generate the
transceiver clock. Its frequency is 156.25 MHz. Use this clock for the MAC
interface to minimize the size of the FIFO between the MAC and SDR XGMII RX
interface.
