Delayed CRC defines number of bytes that are in front of the ethernet frame (header). This header
usually doesn't exist. If exists, then this header is usually not send so the crc calculation must
start later.
About ByteCntGreat2: There must be some data received in order to generate the Rx end frame.

hi,
Can anyone tell me the function of register ByteCntGreat2 in the following statement:
assign GenerateRxEndFrm = StateData[0] & (~MRxDV & ByteCntGreat2 | ByteCntMaxFrame);
And the function of DlyCrcEn,why delay CRC calculation?
Thanks,
yxzhou.
