Implement the ethtool function to support users to obtain network card information, including obtaining various device settings, Report whether physical link is up, Report pause parameters, Set pause parameters, Return a set of strings that describe the requested objects, Get number of strings that @get_strings will write, Return extended statistics about the device.
