Note that my RX performance issue arises with the latest Intel e1000e driver,
1.1.2-NAPI, and an older Intel driver, 0.5.18.3-NAPI, as well. I can't get an
even older version of the driver, 0.4.1.7, to compile on Linux 2.6.31, probably
because the kernel API has changed since that driver was released.
