A problem with crc-32 check

    I`m doing a project in VHDL concerning ethernet, and I have a problem with
    CRC-32 (polynomial x"04C11DB7").
    CRC is initialized into x"ffffffff", after sending all the bytes of the
    frame 4 bytes with zeros are sent to CRC generetor to calculate CRC. Is that
    the value of CRC I have to send to the next layer (phy -> ethernet) after
    sending the frame?
    I tried everything, but CRC is never x"00000000"...

    Here`s the crc-32 generator I`m using:
