| * struct ethtool_cmd - DEPRECATED, link control and status |
| * This structure is DEPRECATED, please use struct ethtool_link_settings. |
| * @cmd: Command number = %ETHTOOL_GSET or %ETHTOOL_SSET |
| * @supported: Bitmask of %SUPPORTED_* flags for the link modes, |
| * physical connectors and other link features for which the |
| * interface supports autonegotiation or auto-detection. |
| * Read-only. |
| * @advertising: Bitmask of %ADVERTISED_* flags for the link modes, |
| * physical connectors and other link features that are |
| * advertised through autonegotiation or enabled for |
| * auto-detection. |
| * @speed: Low bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN |
| * @duplex: Duplex mode; one of %DUPLEX_* |
| * @port: Physical connector type; one of %PORT_* |
| * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not |
| * applicable. For clause 45 PHYs this is the PRTAD. |
| * @transceiver: Historically used to distinguish different possible |
| * PHY types, but not in a consistent way. Deprecated. |
| * @autoneg: Enable/disable autonegotiation and auto-detection; |
| * either %AUTONEG_DISABLE or %AUTONEG_ENABLE |
| * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO |
| * protocols supported by the interface; 0 if unknown. |
| * Read-only. |
| * @maxtxpkt: Historically used to report TX IRQ coalescing; now |
| * obsoleted by &struct ethtool_coalesce. Read-only; deprecated. |
| * @maxrxpkt: Historically used to report RX IRQ coalescing; now |
| * obsoleted by &struct ethtool_coalesce. Read-only; deprecated. |
| * @speed_hi: High bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN |
| * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of |
| * %ETH_TP_MDI_*. If the status is unknown or not applicable, the |
| * value will be %ETH_TP_MDI_INVALID. Read-only. |
| * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of |
| * %ETH_TP_MDI_*. If MDI(-X) control is not implemented, reads |
| * yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected. |
| * When written successfully, the link should be renegotiated if |
| * necessary. |
| * @lp_advertising: Bitmask of %ADVERTISED_* flags for the link modes |
| * and other link features that the link partner advertised |
| * through autonegotiation; 0 if unknown or not applicable. |
| * Read-only. |
| * @reserved: Reserved for future use; see the note on reserved space. |
| * |
| * The link speed in Mbps is split between @speed and @speed_hi. Use |
| * the ethtool_cmd_speed() and ethtool_cmd_speed_set() functions to |
| * access it. |
| * |
| * If autonegotiation is disabled, the speed and @duplex represent the |
| * fixed link mode and are writable if the driver supports multiple |
| * link modes. If it is enabled then they are read-only; if the link |
| * is up they represent the negotiated link mode; if the link is down, |
| * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and |
| * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode. |
| * |
| * Some hardware interfaces may have multiple PHYs and/or physical |
| * connectors fitted or do not allow the driver to detect which are |
| * fitted. For these interfaces @port and/or @phy_address may be |
| * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE. |
| * Otherwise, attempts to write different values may be ignored or |
| * rejected. |
| * |
| * Users should assume that all fields not marked read-only are |
| * writable and subject to validation by the driver. They should use |
| * %ETHTOOL_GSET to get the current values before making specific |
| * changes and then applying them with %ETHTOOL_SSET. |
| * |
| * Deprecated fields should be ignored by both users and drivers. |

| * struct ethtool_link_settings - link control and status |
| * |
| * IMPORTANT, Backward compatibility notice: When implementing new |
| * user-space tools, please first try %ETHTOOL_GLINKSETTINGS, and |
| * if it succeeds use %ETHTOOL_SLINKSETTINGS to change link |
| * settings; do not use %ETHTOOL_SSET if %ETHTOOL_GLINKSETTINGS |
| * succeeded: stick to %ETHTOOL_GLINKSETTINGS/%SLINKSETTINGS in |
| * that case. Conversely, if %ETHTOOL_GLINKSETTINGS fails, use |
| * %ETHTOOL_GSET to query and %ETHTOOL_SSET to change link |
| * settings; do not use %ETHTOOL_SLINKSETTINGS if |
| * %ETHTOOL_GLINKSETTINGS failed: stick to |
| * %ETHTOOL_GSET/%ETHTOOL_SSET in that case. |
| * |
| * @cmd: Command number = %ETHTOOL_GLINKSETTINGS or %ETHTOOL_SLINKSETTINGS |
| * @speed: Link speed (Mbps) |
| * @duplex: Duplex mode; one of %DUPLEX_* |
| * @port: Physical connector type; one of %PORT_* |
| * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not |
| * applicable. For clause 45 PHYs this is the PRTAD. |
| * @autoneg: Enable/disable autonegotiation and auto-detection; |
| * either %AUTONEG_DISABLE or %AUTONEG_ENABLE |
| * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO |
| * protocols supported by the interface; 0 if unknown. |
| * Read-only. |
| * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of |
| * %ETH_TP_MDI_*. If the status is unknown or not applicable, the |
| * value will be %ETH_TP_MDI_INVALID. Read-only. |
| * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of |
| * %ETH_TP_MDI_*. If MDI(-X) control is not implemented, reads |
| * yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected. |
| * When written successfully, the link should be renegotiated if |
| * necessary. |
| * @link_mode_masks_nwords: Number of 32-bit words for each of the |
| * supported, advertising, lp_advertising link mode bitmaps. For |
| * %ETHTOOL_GLINKSETTINGS: on entry, number of words passed by user |
| * (>= 0); on return, if handshake in progress, negative if |
| * request size unsupported by kernel: absolute value indicates |
| * kernel expected size and all the other fields but cmd |
| * are 0; otherwise (handshake completed), strictly positive |
| * to indicate size used by kernel and cmd field stays |
| * %ETHTOOL_GLINKSETTINGS, all other fields populated by driver. For |
| * %ETHTOOL_SLINKSETTINGS: must be valid on entry, ie. a positive |
| * value returned previously by %ETHTOOL_GLINKSETTINGS, otherwise |
| * refused. For drivers: ignore this field (use kernel's |
| * __ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will |
| * be overwritten by kernel. |
| * @supported: Bitmap with each bit meaning given by |
| * %ethtool_link_mode_bit_indices for the link modes, physical |
| * connectors and other link features for which the interface |
| * supports autonegotiation or auto-detection. Read-only. |
| * @advertising: Bitmap with each bit meaning given by |
| * %ethtool_link_mode_bit_indices for the link modes, physical |
| * connectors and other link features that are advertised through |
| * autonegotiation or enabled for auto-detection. |
| * @lp_advertising: Bitmap with each bit meaning given by |
| * %ethtool_link_mode_bit_indices for the link modes, and other |
| * link features that the link partner advertised through |
| * autonegotiation; 0 if unknown or not applicable. Read-only. |
| * @transceiver: Used to distinguish different possible PHY types, |
| * reported consistently by PHYLIB. Read-only. |
| * @master_slave_cfg: Master/slave port mode. |
| * @master_slave_state: Master/slave port state. |
| * @reserved: Reserved for future use; see the note on reserved space. |
| * @reserved1: Reserved for future use; see the note on reserved space. |
| * @link_mode_masks: Variable length bitmaps. |
| * |
| * If autonegotiation is disabled, the speed and @duplex represent the |
| * fixed link mode and are writable if the driver supports multiple |
| * link modes. If it is enabled then they are read-only; if the link |
| * is up they represent the negotiated link mode; if the link is down, |
| * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and |
| * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode. |
| * |
| * Some hardware interfaces may have multiple PHYs and/or physical |
| * connectors fitted or do not allow the driver to detect which are |
| * fitted. For these interfaces @port and/or @phy_address may be |
| * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE. |
| * Otherwise, attempts to write different values may be ignored or |
| * rejected. |
| * |
| * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt |
| * are not available in %ethtool_link_settings. These fields will be |
| * always set to zero in %ETHTOOL_GSET reply and %ETHTOOL_SSET will |
| * fail if any of them is set to non-zero value. |
| * |
| * Users should assume that all fields not marked read-only are |
| * writable and subject to validation by the driver. They should use |
| * %ETHTOOL_GLINKSETTINGS to get the current values before making specific |
| * changes and then applying them with %ETHTOOL_SLINKSETTINGS. |
| * |
| * Drivers that implement %get_link_ksettings and/or |
| * %set_link_ksettings should ignore the @cmd |
| * and @link_mode_masks_nwords fields (any change to them overwritten |
| * by kernel), and rely only on kernel's internal |
| * %__ETHTOOL_LINK_MODE_MASK_NBITS and |
| * %ethtool_link_mode_mask_t. Drivers that implement |
| * %set_link_ksettings() should validate all fields other than @cmd |
| * and @link_mode_masks_nwords that are not described as read-only or |
| * deprecated, and must ignore all fields described as read-only. |
