define KernelPackage/$(KMOD_NAME)/description
 In Intel processor with SSE4.2 supported, the processor will support CRC32C implementation using hardware accelerated CRC32 instruction. 
 This option will create 'crc32c-intel' module, which will enable any routine to use the hardware accelerated CRC32 instruction
 Module will be crc32c-intel
