CRC32c computation is not valid when buffer length is not a multiple of 4 bytes. Values returned by rte_hash_crc functions does not match the one computed by a trivial crc32c implementation.
First patch fixes crc hash function autotests, to outline the problem. Second patch fixes CRC32c computation.
