5 Network Interface Configuration
To manage and configure the network properties of the LAN8670, the “ethtool” command line utility is used.
Important: The “ethtool” version should be 6.7 or later,
            since older versions do not support PLCA settings.
        In this test, “ethtool” version 6.11 is used.
- Check the “ethtool” version of
                    your Linux kernel image. 
$ ethtool --version
