RE: [802.3ae] ethernet CRC


   You can start with all zeroes however u will lock
yourself out so it is prudent to start all FFs with 
ones at reset AND to have a all-zero 
detection-prevention circuit.

Subject: [802.3ae] ethernet CRC


Some items for CRC calculation are not clear for me.
What's the initial state for the computation (all 0s, all 1s or other)?
Can I have a numerical example of  Ethernet CRC-32 calculation, please?

Best regards,
