  20. CRC 32 table of all possible single-byte values. The table is
  21. the CRC of all possible eight bit values. This is all the info
  22. needed to generate 32-bit CRC's on data one a byte at a time 
  23. for all combinations of CRC register values and incoming bytes.   
  24. This table was generated with the makeCRC32() function. It is
  25. based on the Autodin/Ethernet/ADCCP polynomial of 0x4C11DB7:
  26. 0000 0100 1100 0001 0001 1101 1011 0111 (binary) or a poly of
  27. x^32+x^26+x^23+x^22+x^16+x^12+x^11+x^10+x^8+x^7 +x^5+x^4+x^2+x^1+x^0
  28. In this representation the coefficient of x^0 is stored in the 
  29. MSB of the 32-bit word and the coefficient of x^31 is stored in 
  30. the LSB. Thus 0x4C11DB7 becomes 0xEDB88320:
  31. 1110 1101 1011 1000 1000 0011 0010 0000 (binary)
