Doing such a test sets you up for a failure. If a vendor of the card provides an on-chip TCP, it is entirely in the vendor's interest to penalize regular TCP (for example, by failing to provide checksum offload or sane S/G segments). I only consider fair a test of on-chip TCP compared to the best of the normal NICs. Sorry, I should have stated this explicitly. The same card must have SG/Checksumming capability for the no-TCP-onchip portion of the test.
