The implementation may update the indicator + * asynchronously or synchronously, but in either case it must return + * quickly. It is initially called with the argument %ETHTOOL_ID_ACTIVE, + * and must either activate asynchronous updates and return zero, return + * a negative error or return a positive frequency for synchronous + * indication (e.g. 1 for one on/off cycle per second). If it returns + * a frequency then it will be called again at intervals with the + * argument %ETHTOOL_ID_ON or %ETHTOOL_ID_OFF and should set the state of + * the indicator accordingly. Finally, it is called with the argument + * %ETHTOOL_ID_INACTIVE and must deactivate the indicator.

Arguments which are set to %NULL or zero + * will remain unchanged. + * Returns a negative error code or zero.
