- * This is a basic crc64 implementation following ECMA-182 specification,
- * which can be found from,
- * http://www.ecma-international.org/publications/standards/Ecma-182.htm
- *
- * Dr. Ross N. Williams has a great document to introduce the idea of CRC
- * algorithm, here the CRC64 code is also inspired by the table-driven
- * algorithm and detail example from this paper. This paper can be found

- * http://www.ross.net/crc/download/crc_v3.txt
- *
- * crc64table[256] is the lookup table of a table-driven 64-bit CRC
- * calculation, which is generated by gen_crc64table.c in kernel build
- * time. The polynomial of crc64 arithmetic is from ECMA-182 specification
- * as well, which is defined as,
- *
- * x^64 + x^62 + x^57 + x^55 + x^54 + x^53 + x^52 + x^47 + x^46 + x^45 +
- * x^40 + x^39 + x^38 + x^37 + x^35 + x^33 + x^32 + x^31 + x^29 + x^27 +
- * x^24 + x^23 + x^22 + x^21 + x^19 + x^17 + x^13 + x^12 + x^10 + x^9 +
- * x^7 + x^4 + x + 1
