Anything beyond basic host-only TOE adds massive complexity for very little gain: interfacing netfilter and routing code with a black box we _hope_ will act properly sounds like suicide. > Current offloads such as checksum and > segmentation will not be enough for 10GbE processing, so it would have > to be something more than we have today. All this is vague handwaving without supporting evidence. So far we get stuff like Internet2 speed records _without_ TOE. And Linux currently supports 10gige... and hosts are just going to keep getting faster and faster. Jeff
