​Intel Unified Driver Statistics

Intel also offers a new framework by which statistics gathered by ethtool or similar tools utilize a common naming scheme for Intel® Ethernet Linux drivers. When one utilizes ethtool to read information from an Ethernet device, such as statistics, the driver returns a buffer with the strings for the various statistics. There is no standard naming convention for these statistics. Many variations exist between the various Intel® Ethernet devices. For these reasons and more, a common statistics naming scheme has been created.
