30 * struct ethtool_cmd - DEPRECATED, link control and status
31 * This structure is DEPRECATED, please use struct ethtool_link_settings.
32 * @cmd: Command number = %ETHTOOL_GSET or %ETHTOOL_SSET
33 * @supported: Bitmask of %SUPPORTED_* flags for the link modes,
34 * physical connectors and other link features for which the
35 * interface supports autonegotiation or auto-detection.
36 * Read-only.
37 * @advertising: Bitmask of %ADVERTISED_* flags for the link modes,
38 * physical connectors and other link features that are
39 * advertised through autonegotiation or enabled for
40 * auto-detection.
41 * @speed: Low bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
42 * @duplex: Duplex mode; one of %DUPLEX_*
43 * @port: Physical connector type; one of %PORT_*
44 * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
45 * applicable. For clause 45 PHYs this is the PRTAD.
46 * @transceiver: Historically used to distinguish different possible
47 * PHY types, but not in a consistent way. Deprecated.
48 * @autoneg: Enable/disable autonegotiation and auto-detection;
49 * either %AUTONEG_DISABLE or %AUTONEG_ENABLE
50 * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO
51 * protocols supported by the interface; 0 if unknown.
52 * Read-only.
53 * @maxtxpkt: Historically used to report TX IRQ coalescing; now
54 * obsoleted by &struct ethtool_coalesce. Read-only; deprecated.
55 * @maxrxpkt: Historically used to report RX IRQ coalescing; now
56 * obsoleted by &struct ethtool_coalesce. Read-only; deprecated.
57 * @speed_hi: High bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
58 * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
59 * %ETH_TP_MDI_*. If the status is unknown or not applicable, the
60 * value will be %ETH_TP_MDI_INVALID. Read-only.
61 * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
62 * %ETH_TP_MDI_*. If MDI(-X) control is not implemented, reads
63 * yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
64 * When written successfully, the link should be renegotiated if
65 * necessary.
66 * @lp_advertising: Bitmask of %ADVERTISED_* flags for the link modes
67 * and other link features that the link partner advertised
68 * through autonegotiation; 0 if unknown or not applicable.
69 * Read-only.
70 *
71 * The link speed in Mbps is split between @speed and @speed_hi. Use
72 * the ethtool_cmd_speed() and ethtool_cmd_speed_set() functions to
73 * access it.
74 *
75 * If autonegotiation is disabled, the speed and @duplex represent the
76 * fixed link mode and are writable if the driver supports multiple
77 * link modes. If it is enabled then they are read-only; if the link
78 * is up they represent the negotiated link mode; if the link is down,
79 * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
80 * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
81 *
82 * Some hardware interfaces may have multiple PHYs and/or physical
83 * connectors fitted or do not allow the driver to detect which are
84 * fitted. For these interfaces @port and/or @phy_address may be
85 * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
86 * Otherwise, attempts to write different values may be ignored or
87 * rejected.
88 *
89 * Users should assume that all fields not marked read-only are
90 * writable and subject to validation by the driver. They should use
91 * %ETHTOOL_GSET to get the current values before making specific
92 * changes and then applying them with %ETHTOOL_SSET.
93 *
94 * Drivers that implement set_settings() should validate all fields
95 * other than @cmd that are not described as read-only or deprecated,
96 * and must ignore all fields described as read-only.
97 *
98 * Deprecated fields should be ignored by both users and drivers.

1735 * %ETHTOOL_GSET to query and %ETHTOOL_SSET to change link
1736 * settings; do not use %ETHTOOL_SLINKSETTINGS if
1737 * %ETHTOOL_GLINKSETTINGS failed: stick to
1738 * %ETHTOOL_GSET/%ETHTOOL_SSET in that case.
1739 *
1740 * @cmd: Command number = %ETHTOOL_GLINKSETTINGS or %ETHTOOL_SLINKSETTINGS
1741 * @speed: Link speed (Mbps)
1742 * @duplex: Duplex mode; one of %DUPLEX_*
1743 * @port: Physical connector type; one of %PORT_*
1744 * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
1745 * applicable. For clause 45 PHYs this is the PRTAD.
1746 * @autoneg: Enable/disable autonegotiation and auto-detection;
1747 * either %AUTONEG_DISABLE or %AUTONEG_ENABLE
1748 * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO
1749 * protocols supported by the interface; 0 if unknown.
1750 * Read-only.
1751 * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
1752 * %ETH_TP_MDI_*. If the status is unknown or not applicable, the
1753 * value will be %ETH_TP_MDI_INVALID. Read-only.
1754 * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
1755 * %ETH_TP_MDI_*. If MDI(-X) control is not implemented, reads
1756 * yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
1757 * When written successfully, the link should be renegotiated if
1758 * necessary.
1759 * @link_mode_masks_nwords: Number of 32-bit words for each of the
1760 * supported, advertising, lp_advertising link mode bitmaps. For
1761 * %ETHTOOL_GLINKSETTINGS: on entry, number of words passed by user
1762 * (>= 0); on return, if handshake in progress, negative if
1763 * request size unsupported by kernel: absolute value indicates
1764 * kernel expected size and all the other fields but cmd
1765 * are 0; otherwise (handshake completed), strictly positive
1766 * to indicate size used by kernel and cmd field stays
1767 * %ETHTOOL_GLINKSETTINGS, all other fields populated by driver. For
1768 * %ETHTOOL_SLINKSETTINGS: must be valid on entry, ie. a positive
1769 * value returned previously by %ETHTOOL_GLINKSETTINGS, otherwise
1770 * refused. For drivers: ignore this field (use kernel's
1771 * __ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will
1772 * be overwritten by kernel.
1773 * @supported: Bitmap with each bit meaning given by
1774 * %ethtool_link_mode_bit_indices for the link modes, physical
1775 * connectors and other link features for which the interface
1776 * supports autonegotiation or auto-detection. Read-only.
1777 * @advertising: Bitmap with each bit meaning given by
1778 * %ethtool_link_mode_bit_indices for the link modes, physical
1779 * connectors and other link features that are advertised through
1780 * autonegotiation or enabled for auto-detection.
1781 * @lp_advertising: Bitmap with each bit meaning given by
1782 * %ethtool_link_mode_bit_indices for the link modes, and other
1783 * link features that the link partner advertised through
1784 * autonegotiation; 0 if unknown or not applicable. Read-only.
1785 * @transceiver: Used to distinguish different possible PHY types,
1786 * reported consistently by PHYLIB. Read-only.
1787 *
1788 * If autonegotiation is disabled, the speed and @duplex represent the
1789 * fixed link mode and are writable if the driver supports multiple
1790 * link modes. If it is enabled then they are read-only; if the link
1791 * is up they represent the negotiated link mode; if the link is down,
1792 * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
1793 * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
1794 *
1795 * Some hardware interfaces may have multiple PHYs and/or physical
1796 * connectors fitted or do not allow the driver to detect which are
1797 * fitted. For these interfaces @port and/or @phy_address may be
1798 * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
1799 * Otherwise, attempts to write different values may be ignored or
1800 * rejected.
1801 *
1802 * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt
1803 * are not available in %ethtool_link_settings. Until all drivers are
1804 * converted to ignore them or to the new %ethtool_link_settings API,
1805 * for both queries and changes, users should always try
1806 * %ETHTOOL_GLINKSETTINGS first, and if it fails with -ENOTSUPP stick
1807 * only to %ETHTOOL_GSET and %ETHTOOL_SSET consistently. If it
1808 * succeeds, then users should stick to %ETHTOOL_GLINKSETTINGS and
1809 * %ETHTOOL_SLINKSETTINGS (which would support drivers implementing
1810 * either %ethtool_cmd or %ethtool_link_settings).
1811 *
1812 * Users should assume that all fields not marked read-only are
1813 * writable and subject to validation by the driver. They should use
1814 * %ETHTOOL_GLINKSETTINGS to get the current values before making specific
1815 * changes and then applying them with %ETHTOOL_SLINKSETTINGS.
1816 *
1817 * Drivers that implement %get_link_ksettings and/or
1818 * %set_link_ksettings should ignore the @cmd
1819 * and @link_mode_masks_nwords fields (any change to them overwritten
1820 * by kernel), and rely only on kernel's internal
1821 * %__ETHTOOL_LINK_MODE_MASK_NBITS and
1822 * %ethtool_link_mode_mask_t. Drivers that implement
1823 * %set_link_ksettings() should validate all fields other than @cmd
1824 * and @link_mode_masks_nwords that are not described as read-only or
1825 * deprecated, and must ignore all fields described as read-only.
