Not sure what We meant here. TCP standard requires checksums to be set, you cannot 'disable it'. Only possible thing in linux stack is to offload tcp checksum computation to network card, if hardware permits it. By the way, the loopback interface (lo) pretends to support this feature, so we dont compute tcp checksums for loopback. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
