We should be getting some benefit on the receive path, where the
checksum is normally forced to happen independent of a copy. Having this
offloaded to hardware should produce some measureable gain.

Ah, I forgot about that. But rx csum was not being toggled in the experiment.

The external bandwidth was definitely very low, so I guess there must be some other bottleneck in Bin's setup.
