You assume that nothing in the stack mangles the packet and would benefit from having the 1's complement to work with in order to assist with checksum adjustments etc. So we want 1's complement, all the time. All of the headers get touched anyways as each layer of the stack demuxes the packet. Therefore there is _ZERO_ cost to use 1's complement to validate checksums in input. It's always superior. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
