The CRC algorithm implemented in this module (CRC-32 Ethernet polynomial: 0x4C11DB7) offers
excellent features in terms of error detection in the message. Therefore permanent and transient
faults affecting CRC computations are easily detected by any operations using the module to
recompute an expected signature
