+ <para>After a new .link file has been created, or an exisiting .link file modified, the new settings
+ may be applied to the matching interface with the following commands:</para>
+
+ <programlisting>$ sudo udevadm control --reload
+$ sudo ip link set eth0 down
+$ sudo udevadm trigger --verbose --settle --action add /sys/class/net/eth0</programlisting>
+
+ <para>You may also need to stop the service that manages the network interface, e.g.
+ <filename>systemd-networkd.service</filename> or <filename>NetworkManager.service</filename> before
+ the above operation, and then restart the service after that. For more details about
