Conversely, as data is received by the LAN9118, it is moved from the MAC to the RX MIL FIFO, and
then into the RX data FIFO. When the RX data FIFO fills up, data will continue to collect in the RX
MIL FIFO. If the RX MIL FIFO fills up and overruns, subsequent RX frames will be lost until room is
made in the RX data FIFO. For each frame of data that is lost, the RX Dropped Frames Counter
(RX_DROP) is incremented.
RX and TX MIL FIFO levels are not visible to the host processor. RX and TX MIL FIFOs operate
independent of the TX adatand RX data and status FIFOs. FIFO levels set for the RX and TX data
and Status FIFOs do not take into consideration the MIL FIFOs.
