+         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.
