RX Data FIFO Fast Forward (RX_FFWD)
Writing a 1 to this bit causes the RX Data FIFO to fast-forward to the start
of the next frame. This bit will remain high until the RX Data FIFO fast-
forward operation has completed. No reads should be issued to the RX Data
FIFO while this bit is high.
Note:
RESERVED
Receive Datapath Control Register (RX_DP_CTRL)
