 320  *      asynchronously or synchronously, but in either case it must return
 321  *      quickly.  It is initially called with the argument %ETHTOOL_ID_ACTIVE,

 323  *      a negative error or return a positive frequency for synchronous

 396  *      Returns a negative error code or zero.
 397  * @get_link_ksettings: Get various device settings including Ethernet link
 398  *      settings. The %cmd and %link_mode_masks_nwords fields should be
 399  *      ignored (use %__ETHTOOL_LINK_MODE_MASK_NBITS instead of the latter),
 400  *      any change to them will be overwritten by kernel. Returns a negative
 401  *      error code or zero.
 402  * @set_link_ksettings: Set various device settings including Ethernet link
 403  *      settings. The %cmd and %link_mode_masks_nwords fields should be

 408  * @set_fecparam: Set the network device Forward Error Correction parameters.
 409  * @get_ethtool_phy_stats: Return extended statistics about the PHY device.
 410  *      This is only useful if the device maintains PHY statistics and
 411  *      cannot use the standard PHY library helpers.
 412  *
 413  * All operations are optional (i.e. the function pointer may be set
 414  * to %NULL) and callers must take this into account.  Callers must
 415  * hold the RTNL lock.
 416  *
 417  * See the structures used by these operations for further documentation.
 418  * Note that for all operations using a structure ending with a zero-
 419  * length array, the array is allocated separately in the kernel and
 420  * is passed to the driver as an additional parameter.
 421  *
