Sure :). The motivation for seeing the stats though would be to get an idea of how much retransmission/SACK etc activity _is_ occurring during Troy's SpecWeb runs, which would give us an idea of how often we're actually doing segmentation offload, and better idea of how much gain its possible to further get from this(ahem) DMA coalescing :). Some of Troy's early runs had a very large number of packets dropped by the card.
One thing to do is make absolutely sure that flow control is enabled and supported by all devices on the link from the client to the test spedweb server.
Troy can do you do that for us along with the statistic dumps?
