+     * supported by the network interface. Implementation templates are
+     * described as a list of enum lists, and each transmission mode is
+     * expressed as a combination of enum values. Each enum list has an enum id
+     * (attribute id) and a list of enum values. The i-th transmission mode is a
+     * combination of i-th values of each enum list.
+     *
+     * Implementation templates also represent the preference among the
+     * transmission modes. When only a part of the parameters corresponds to the
+     * transmission mode is configured, then the first mode that matches the
+     * current configured value will be used. Therefore the head of the list is
+     * the default mode.
