827 * quickly. It is initially called with the argument %ETHTOOL_ID_ACTIVE,
Allan, Bruce Wfce55922011-04-13 13:09:10 +0000828 * and must either activate asynchronous updates and return zero, return
829 * a negative error or return a positive frequency for synchronous

880 * to %NULL) and callers must take this into account. Callers must
881 * hold the RTNL, except that for @get_drvinfo the caller may or may
882 * not hold the RTNL.
