Interlaken CRC32 Generator and Checker
CRC-32 provides a diagnostic tool on a per-lane basis. You can use CRC-32 to trace interface errors back
to an individual lane. The CRC-32 calculation covers the whole metaframe including the Diagnostic
Word itself. This CRC code value is stored in the CRC32 field of the Diagnostic Word. The following
table describes the CRC-32 parameters.
