Well if you did GRO instead of LRO then none of this would matter :)I get aggregate 18Gbps with LRO v/s 12Gbps without, so it's very much a useful feature for me.
Sorry we are each talking about different things. The performance difference you observed is software GRO vs. hardware LRO. What I was talking about above is switching the Intel hardware to do GRO instead of LRO.
