Log Message:
Performance improvements for PCIe and 8168 based devices:
- When using the countdown timer for interrupt moderation on PCIe devices,
use a timer rate value based on a 125MHz PCIe reference clock instead of
33 MHz.
- For 8168 based devices, ditch the countdown timer and instead use the
(undocumented) hardware interrupt moderation feature.
- Support TSOv4 on 8168D and later devices.
