2004 * Some hardware interfaces may have multiple PHYs and/or physical
2005 * connectors fitted or do not allow the driver to detect which are
2006 * fitted. For these interfaces @port and/or @phy_address may be
2007 * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
2008 * Otherwise, attempts to write different values may be ignored or
2011 * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt
2012 * are not available in %ethtool_link_settings. These fields will be
2013 * always set to zero in %ETHTOOL_GSET reply and %ETHTOOL_SSET will
2014 * fail if any of them is set to non-zero value.
2016 * Users should assume that all fields not marked read-only are
2017 * writable and subject to validation by the driver. They should use
2018 * %ETHTOOL_GLINKSETTINGS to get the current values before making specific
2019 * changes and then applying them with %ETHTOOL_SLINKSETTINGS.
2021 * Drivers that implement %get_link_ksettings and/or
2022 * %set_link_ksettings should ignore the @cmd
2023 * and @link_mode_masks_nwords fields (any change to them overwritten
2024 * by kernel), and rely only on kernel's internal
2025 * %__ETHTOOL_LINK_MODE_MASK_NBITS and
2026 * %ethtool_link_mode_mask_t. Drivers that implement
2027 * %set_link_ksettings() should validate all fields other than @cmd
2028 * and @link_mode_masks_nwords that are not described as read-only or
2029 * deprecated, and must ignore all fields described as read-only.
