I'm can tell you the reason for the change: IP header checksum was removed in IPv6, and requiring checksumming in upper layer was required to partially compensate for the fact. Most often, the cost for checksum computation is rather low and errors happen quite infrequently, but I guess that's no consolation.. -- Pekka Savola "Tell me of difficulties surmounted, Netcore Oy not those you stumble over and fall" Systems.
