29 : * This structure is DEPRECATED, please use struct ethtool_link_settings.
30 : * @cmd: Command number = %ETHTOOL_GSET or %ETHTOOL_SSET
31 : * @supported: Bitmask of %SUPPORTED_* flags for the link modes,
32 : * physical connectors and other link features for which the
33 : * interface supports autonegotiation or auto-detection.
34 : * Read-only.
35 : * @advertising: Bitmask of %ADVERTISED_* flags for the link modes,
36 : * physical connectors and other link features that are
37 : * advertised through autonegotiation or enabled for
38 : * auto-detection.
39 : * @speed: Low bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
40 : * @duplex: Duplex mode; one of %DUPLEX_*
41 : * @port: Physical connector type; one of %PORT_*
42 : * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
43 : * applicable. For clause 45 PHYs this is the PRTAD.
44 : * @transceiver: Historically used to distinguish different possible
45 : * PHY types, but not in a consistent way. Deprecated.
46 : * @autoneg: Enable/disable autonegotiation and auto-detection;
47 : * either %AUTONEG_DISABLE or %AUTONEG_ENABLE
48 : * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO
49 : * protocols supported by the interface; 0 if unknown.
50 : * Read-only.
51 : * @maxtxpkt: Historically used to report TX IRQ coalescing; now
52 : * obsoleted by &struct ethtool_coalesce. Read-only; deprecated.
53 : * @maxrxpkt: Historically used to report RX IRQ coalescing; now
54 : * obsoleted by &struct ethtool_coalesce. Read-only; deprecated.
55 : * @speed_hi: High bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
56 : * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
57 : * %ETH_TP_MDI_*. If the status is unknown or not applicable, the
58 : * value will be %ETH_TP_MDI_INVALID. Read-only.
59 : * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
60 : * %ETH_TP_MDI_*. If MDI(-X) control is not implemented, reads
61 : * yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
62 : * When written successfully, the link should be renegotiated if
63 : * necessary.
64 : * @lp_advertising: Bitmask of %ADVERTISED_* flags for the link modes
65 : * and other link features that the link partner advertised
66 : * through autonegotiation; 0 if unknown or not applicable.
67 : * Read-only.
68 : *
69 : * The link speed in Mbps is split between @speed and @speed_hi. Use
70 : * the ethtool_cmd_speed() and ethtool_cmd_speed_set() functions to
71 : * access it.
72 : *
73 : * If autonegotiation is disabled, the speed and @duplex represent the
74 : * fixed link mode and are writable if the driver supports multiple
75 : * link modes. If it is enabled then they are read-only; if the link
76 : * is up they represent the negotiated link mode; if the link is down,
77 : * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
78 : * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
79 : *
80 : * Some hardware interfaces may have multiple PHYs and/or physical
81 : * connectors fitted or do not allow the driver to detect which are
82 : * fitted. For these interfaces @port and/or @phy_address may be
83 : * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
84 : * Otherwise, attempts to write different values may be ignored or
85 : * rejected.
86 : *
87 : * Users should assume that all fields not marked read-only are
88 : * writable and subject to validation by the driver. They should use
89 : * %ETHTOOL_GSET to get the current values before making specific
90 : * changes and then applying them with %ETHTOOL_SSET.
91 : *
92 : * Drivers that implement set_settings() should validate all fields
93 : * other than @cmd that are not described as read-only or deprecated,
94 : * and must ignore all fields described as read-only.
95 : *
96 : * Deprecated fields should be ignored by both users and drivers.

1707 : * %ETHTOOL_GLINKSETTINGS failed: stick to
1708 : * %ETHTOOL_GSET/%ETHTOOL_SSET in that case.
1709 : *
1710 : * @cmd: Command number = %ETHTOOL_GLINKSETTINGS or %ETHTOOL_SLINKSETTINGS
1711 : * @speed: Link speed (Mbps)
1712 : * @duplex: Duplex mode; one of %DUPLEX_*
1713 : * @port: Physical connector type; one of %PORT_*
1714 : * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
1715 : * applicable. For clause 45 PHYs this is the PRTAD.
1716 : * @autoneg: Enable/disable autonegotiation and auto-detection;
1717 : * either %AUTONEG_DISABLE or %AUTONEG_ENABLE
1718 : * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO
1719 : * protocols supported by the interface; 0 if unknown.
1720 : * Read-only.
1721 : * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
1722 : * %ETH_TP_MDI_*. If the status is unknown or not applicable, the
1723 : * value will be %ETH_TP_MDI_INVALID. Read-only.
1724 : * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
1725 : * %ETH_TP_MDI_*. If MDI(-X) control is not implemented, reads
1726 : * yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
1727 : * When written successfully, the link should be renegotiated if
1728 : * necessary.
1729 : * @link_mode_masks_nwords: Number of 32-bit words for each of the
1730 : * supported, advertising, lp_advertising link mode bitmaps. For
1731 : * %ETHTOOL_GLINKSETTINGS: on entry, number of words passed by user
1732 : * (>= 0); on return, if handshake in progress, negative if
1733 : * request size unsupported by kernel: absolute value indicates
1734 : * kernel expected size and all the other fields but cmd
1735 : * are 0; otherwise (handshake completed), strictly positive
1736 : * to indicate size used by kernel and cmd field stays
1737 : * %ETHTOOL_GLINKSETTINGS, all other fields populated by driver. For
1738 : * %ETHTOOL_SLINKSETTINGS: must be valid on entry, ie. a positive
1739 : * value returned previously by %ETHTOOL_GLINKSETTINGS, otherwise
1740 : * refused. For drivers: ignore this field (use kernel's
1741 : * __ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will
1742 : * be overwritten by kernel.
1743 : * @supported: Bitmap with each bit meaning given by
1744 : * %ethtool_link_mode_bit_indices for the link modes, physical
1745 : * connectors and other link features for which the interface
1746 : * supports autonegotiation or auto-detection. Read-only.
1747 : * @advertising: Bitmap with each bit meaning given by
1748 : * %ethtool_link_mode_bit_indices for the link modes, physical
1749 : * connectors and other link features that are advertised through
1750 : * autonegotiation or enabled for auto-detection.
1751 : * @lp_advertising: Bitmap with each bit meaning given by
1752 : * %ethtool_link_mode_bit_indices for the link modes, and other
1753 : * link features that the link partner advertised through
1754 : * autonegotiation; 0 if unknown or not applicable. Read-only.
1755 : * @transceiver: Used to distinguish different possible PHY types,
1756 : * reported consistently by PHYLIB. Read-only.
1757 : *
1758 : * If autonegotiation is disabled, the speed and @duplex represent the
1759 : * fixed link mode and are writable if the driver supports multiple
1760 : * link modes. If it is enabled then they are read-only; if the link
1761 : * is up they represent the negotiated link mode; if the link is down,
1762 : * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
1763 : * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
1764 : *
1765 : * Some hardware interfaces may have multiple PHYs and/or physical
1766 : * connectors fitted or do not allow the driver to detect which are
1767 : * fitted. For these interfaces @port and/or @phy_address may be
1768 : * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
1769 : * Otherwise, attempts to write different values may be ignored or
1770 : * rejected.
1771 : *
1772 : * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt
1773 : * are not available in %ethtool_link_settings. Until all drivers are
1774 : * converted to ignore them or to the new %ethtool_link_settings API,
1775 : * for both queries and changes, users should always try
1776 : * %ETHTOOL_GLINKSETTINGS first, and if it fails with -ENOTSUPP stick
1777 : * only to %ETHTOOL_GSET and %ETHTOOL_SSET consistently. If it
1778 : * succeeds, then users should stick to %ETHTOOL_GLINKSETTINGS and
1779 : * %ETHTOOL_SLINKSETTINGS (which would support drivers implementing
1780 : * either %ethtool_cmd or %ethtool_link_settings).
1781 : *
1782 : * Users should assume that all fields not marked read-only are
1783 : * writable and subject to validation by the driver. They should use
1784 : * %ETHTOOL_GLINKSETTINGS to get the current values before making specific
1785 : * changes and then applying them with %ETHTOOL_SLINKSETTINGS.
1786 : *
1787 : * Drivers that implement %get_link_ksettings and/or
1788 : * %set_link_ksettings should ignore the @cmd
1789 : * and @link_mode_masks_nwords fields (any change to them overwritten
1790 : * by kernel), and rely only on kernel's internal
1791 : * %__ETHTOOL_LINK_MODE_MASK_NBITS and
1792 : * %ethtool_link_mode_mask_t. Drivers that implement
1793 : * %set_link_ksettings() should validate all fields other than @cmd
1794 : * and @link_mode_masks_nwords that are not described as read-only or
1795 : * deprecated, and must ignore all fields described as read-only.
