            To make these settings permanent you can make use of the <option>ETHTOOL_OPTS</option> directive. It can be used in interface configuration files to set the desired options when the network interface is brought up. Refer to <xref linkend="s2-networkscripts-interfaces-eth0"/> for more details on how to use this directive.
