What is your test setup? Do you have 2 identical boxes?
Does it perform better e.g. on Linux or FreeBSD? If so, you could
check how the config registers get set by that particular OS.

Or the performance are constrained by something unrelated. In the blog
post cited above, the poster acheived more than 5 Gb/s before touching
MMRBC, while I am stuck at 2,7 GB/s. Any new idea welcome.
The blog post refers to PCI-X, I'm more familiar with PCIe, but the concepts
are similar.

Finally, adding cfgread/cfgwrite commands to pcictl seems like a step in
the wrong direction. I know that this is UNIX and we're duty-bound to
give everyone enough rope, but may we reconsider our assisted-suicide

Well, with the part he's using (the 82599, I think) it shouldn't be that

most of Intel's Ethernet
