+ From Intel Westmere and AMD Bulldozer processor with SSE4.2
+ and PCLMULQDQ supported, the processor will support
+ CRC32 PCLMULQDQ implementation using hardware accelerated PCLMULQDQ
+ instruction. This option will create 'crc32-plcmul' module,
+ which will enable any routine to use the CRC-32-IEEE 802.3 checksum
+ and gain better performance as compared with the table implementation.
