Supported 367 * coalescing types should be set in @supported_coalesce_params. 368 * Returns a negative error code or zero. 369 * @get_link_ksettings: Get various device settings including Ethernet link 370 * settings. The %cmd and %link_mode_masks_nwords fields should be 371 * ignored (use %__ETHTOOL_LINK_MODE_MASK_NBITS instead of the latter), 372 * any change to them will be overwritten by kernel. Returns a negative 373 * error code or zero. 374 * @set_link_ksettings: Set various device settings including Ethernet link 375 * settings.
