+          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.
