Maybe GRO could assume the checksums are valid so the checksum would only be verified when the packet is delivered locally. If the packet is forwarded then, provided the same packet boundaries are used, the original checksums (maybe modified by NAT) can be used. No idea how easy this might be :-) David - Registered Address Lakeside, Bramley Road, Mount Farm, Milton Keynes, MK1 1PT, UK Registration No: 1397386 (Wales)
