The linux kernel provides a generic platform independent version of ip_compute_csum() as well as platform optimized versions. Some platforms will disable the generic platform version in favor of the optimized one. If the generic version is disabled and if the checksum.h header from asm-generic is used then we will end up with a undefined symbol error when loading the obdclass module. The solution is to use the platform specific checksum.h header that will handle using the generic or optimized version for us. As a bounus we get better performance with the right kernel configuration.
