- * fletcher checksum functions
- *
- * Note: Fletcher checksum methods expect buffer size to be 4B aligned. This
- * limitation stems from the algorithm design. Performing incremental checksum
- * without said alignment would yield different results. Therefore, the code
- * includes assertions for the size alignment.
- * For compatibility, it is required that some code paths calculate checksum of
- * non-aligned buffer sizes. For this purpose, `fletcher_4_native_varsize()`
- * checksum method is added. This method will ignore last (size % 4) bytes of
- * the data buffer.
