42 : * Read-only.

47 : * @speed: Low bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
48 : * @duplex: Duplex mode; one of %DUPLEX_*
49 : * @port: Physical connector type; one of %PORT_*
50 : * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
51 : * applicable. For clause 45 PHYs this is the PRTAD.
52 : * @transceiver: Historically used to distinguish different possible
53 : * PHY types, but not in a consistent way. Deprecated.

55 : * either %AUTONEG_DISABLE or %AUTONEG_ENABLE

62 : * obsoleted by &struct ethtool_coalesce. Read-only; deprecated.
63 : * @speed_hi: High bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
64 : * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
65 : * %ETH_TP_MDI_*. If the status is unknown or not applicable, the
66 : * value will be %ETH_TP_MDI_INVALID. Read-only.
67 : * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
68 : * %ETH_TP_MDI_*. If MDI(-X) control is not implemented, reads
69 : * yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
70 : * When written successfully, the link should be renegotiated if
71 : * necessary.

75 : * Read-only.
76 : * @reserved: Reserved for future use; see the note on reserved space.

78 : * The link speed in Mbps is split between @speed and @speed_hi. Use
79 : * the ethtool_cmd_speed() and ethtool_cmd_speed_set() functions to
80 : * access it.
81 : *
82 : * If autonegotiation is disabled, the speed and @duplex represent the
83 : * fixed link mode and are writable if the driver supports multiple
84 : * link modes. If it is enabled then they are read-only; if the link
85 : * is up they represent the negotiated link mode; if the link is down,
86 : * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
87 : * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
88 : *
89 : * Some hardware interfaces may have multiple PHYs and/or physical
90 : * connectors fitted or do not allow the driver to detect which are
91 : * fitted. For these interfaces @port and/or @phy_address may be
92 : * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
93 : * Otherwise, attempts to write different values may be ignored or
94 : * rejected.
95 : *
96 : * Users should assume that all fields not marked read-only are
97 : * writable and subject to validation by the driver. They should use
98 : * %ETHTOOL_GSET to get the current values before making specific

2007 : * If autonegotiation is disabled, the speed and @duplex represent the
2008 : * fixed link mode and are writable if the driver supports multiple
2009 : * link modes. If it is enabled then they are read-only; if the link
2010 : * is up they represent the negotiated link mode; if the link is down,
2011 : * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
2012 : * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
2013 : *
2014 : * Some hardware interfaces may have multiple PHYs and/or physical
2015 : * connectors fitted or do not allow the driver to detect which are
2016 : * fitted. For these interfaces @port and/or @phy_address may be
2017 : * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
2018 : * Otherwise, attempts to write different values may be ignored or
2019 : * rejected.
2020 : *
2021 : * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt
2022 : * are not available in %ethtool_link_settings. These fields will be
2023 : * always set to zero in %ETHTOOL_GSET reply and %ETHTOOL_SSET will
2024 : * fail if any of them is set to non-zero value.
2025 : *
2026 : * Users should assume that all fields not marked read-only are
2027 : * writable and subject to validation by the driver. They should use
2028 : * %ETHTOOL_GLINKSETTINGS to get the current values before making specific
2029 : * changes and then applying them with %ETHTOOL_SLINKSETTINGS.
2030 : *
2031 : * Drivers that implement %get_link_ksettings and/or
2032 : * %set_link_ksettings should ignore the @cmd
2033 : * and @link_mode_masks_nwords fields (any change to them overwritten
2034 : * by kernel), and rely only on kernel's internal
2035 : * %__ETHTOOL_LINK_MODE_MASK_NBITS and
2036 : * %ethtool_link_mode_mask_t. Drivers that implement
2037 : * %set_link_ksettings() should validate all fields other than @cmd
2038 : * and @link_mode_masks_nwords that are not described as read-only or
2039 : * deprecated, and must ignore all fields described as read-only.
