Use hardware timer to simulate interrupt moderation. Old devices will no
longer be livelocked when they are receiving on GigE line. Newer devices also gain well controlled interrupt rate. If hardware supports interrupt moderation (e.g. 8168B, 8168C), you could also use hardware based interrupt moderation, however, due to lack of necessary information it does not work as reliably as simulated interrupt moderation. It is _not_ recommended currently. By default, PCIe devices' simulated interrupt moderation timer is set to 75us, while PCI devices' is set to 125us. From sephe@DragonFly
