3.15.1.1
Receive Data FIFO Fast Forward
The RX data path implements an automatic data discard function. Using the RX data FIFO Fast
Forward bit (RX_FFWD) in the RX_DP_CTRL register, the host can instruct the LAN9215 to skip the
packet at the head of the RX data FIFO. The RX data FIFO pointers are automatically incremented to
the beginning of the next RX packet.
