  52  *
  53  * Routine Description:
  54  *
  55  * Computes the CRC32c checksum for the specified buffer using the slicing by 8
  56  * algorithm over 64 bit quantities.
  57  *
  58  * Arguments:
  59  *
  60  *              p_running_crc - pointer to the initial or final remainder value
  61  *                              used in CRC computations. It should be set to
  62  *                              non-NULL if the mode argument is equal to CONT or END
  63  *              p_buf - the packet buffer where crc computations are being performed
  64  *              length - the length of p_buf in bytes
  65  *              init_bytes - the number of initial bytes that need to be processed before
  66  *                                       aligning p_buf to multiples of 4 bytes
  67  *              mode - can be any of the following: BEGIN, CONT, END, BODY, ALIGN
  68  *
  69  * Return value:
  70  *
  71  *              The computed CRC32c value
