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 * Deprecated fields should be ignored by both users and drivers.

1031 * %ETHTOOL_GRXCLSRLALL, %ETHTOOL_SRXCLSRLDEL or %ETHTOOL_SRXCLSRLINS
1032 * @flow_type: Type of flow to be affected, e.g. %TCP_V4_FLOW
1033 * @data: Command-dependent value
1034 * @fs: Flow classification rule
1035 * @rss_context: RSS context to be affected
1036 * @rule_cnt: Number of rules to be affected
1037 * @rule_locs: Array of used rule locations
1038 *
1039 * For %ETHTOOL_GRXFH and %ETHTOOL_SRXFH, @data is a bitmask indicating
1040 * the fields included in the flow hash, e.g. %RXH_IP_SRC. The following
1041 * structure fields must not be used, except that if @flow_type includes
1042 * the %FLOW_RSS flag, then @rss_context determines which RSS context to
1043 * act on.
1044 *
1045 * For %ETHTOOL_GRXRINGS, @data is set to the number of RX rings/queues
1046 * on return.
1047 *
1048 * For %ETHTOOL_GRXCLSRLCNT, @rule_cnt is set to the number of defined
1049 * rules on return. If @data is non-zero on return then it is the
1050 * size of the rule table, plus the flag %RX_CLS_LOC_SPECIAL if the
1051 * driver supports any special location values. If that flag is not
1052 * set in @data then special location values should not be used.
1053 *
1054 * For %ETHTOOL_GRXCLSRULE, @fs.@location specifies the location of an
1055 * existing rule on entry and @fs contains the rule on return; if
1056 * @fs.@flow_type includes the %FLOW_RSS flag, then @rss_context is
1057 * filled with the RSS context ID associated with the rule.
1058 *
1059 * For %ETHTOOL_GRXCLSRLALL, @rule_cnt specifies the array size of the
1060 * user buffer for @rule_locs on entry. On return, @data is the size
1061 * of the rule table, @rule_cnt is the number of defined rules, and
1062 * @rule_locs contains the locations of the defined rules. Drivers
1063 * must use the second parameter to get_rxnfc() instead of @rule_locs.
1064 *
1065 * For %ETHTOOL_SRXCLSRLINS, @fs specifies the rule to add or update.
1066 * @fs.@location either specifies the location to use or is a special
1067 * location value with %RX_CLS_LOC_SPECIAL flag set. On return,
1068 * @fs.@location is the actual rule location. If @fs.@flow_type
1069 * includes the %FLOW_RSS flag, @rss_context is the RSS context ID to
1070 * use for flow spreading traffic which matches this rule. The value
1071 * from the rxfh indirection table will be added to @fs.@ring_cookie
1072 * to choose which ring to deliver to.
1073 *
1074 * For %ETHTOOL_SRXCLSRLDEL, @fs.@location specifies the location of an
1075 * existing rule on entry.
1076 *
1077 * A driver supporting the special location values for
1078 * %ETHTOOL_SRXCLSRLINS may add the rule at any suitable unused
1079 * location, and may remove a rule at a later location (lower
1080 * priority) that matches exactly the same set of flows. The special

1082 * %RX_CLS_LOC_FIRST, selecting the first suitable location (maximum
1083 * priority); and %RX_CLS_LOC_LAST, selecting the last suitable
1084 * location (minimum priority). Additional special values may be
1085 * defined in future and drivers must return -%EINVAL for any

1911 * %ETHTOOL_GLINKSETTINGS failed: stick to
1912 * %ETHTOOL_GSET/%ETHTOOL_SSET in that case.
1913 *
1914 * @cmd: Command number = %ETHTOOL_GLINKSETTINGS or %ETHTOOL_SLINKSETTINGS
1915 * @speed: Link speed (Mbps)
1916 * @duplex: Duplex mode; one of %DUPLEX_*
1917 * @port: Physical connector type; one of %PORT_*
1918 * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
1919 * applicable. For clause 45 PHYs this is the PRTAD.
1920 * @autoneg: Enable/disable autonegotiation and auto-detection;
1921 * either %AUTONEG_DISABLE or %AUTONEG_ENABLE
1922 * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO
1923 * protocols supported by the interface; 0 if unknown.
1924 * Read-only.
1925 * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
1926 * %ETH_TP_MDI_*. If the status is unknown or not applicable, the
1927 * value will be %ETH_TP_MDI_INVALID. Read-only.
1928 * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
1929 * %ETH_TP_MDI_*. If MDI(-X) control is not implemented, reads
1930 * yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
1931 * When written successfully, the link should be renegotiated if
1932 * necessary.
1933 * @link_mode_masks_nwords: Number of 32-bit words for each of the
1934 * supported, advertising, lp_advertising link mode bitmaps. For
1935 * %ETHTOOL_GLINKSETTINGS: on entry, number of words passed by user
1936 * (>= 0); on return, if handshake in progress, negative if
1937 * request size unsupported by kernel: absolute value indicates
1938 * kernel expected size and all the other fields but cmd
1939 * are 0; otherwise (handshake completed), strictly positive
1940 * to indicate size used by kernel and cmd field stays
1941 * %ETHTOOL_GLINKSETTINGS, all other fields populated by driver. For
1942 * %ETHTOOL_SLINKSETTINGS: must be valid on entry, ie. a positive
1943 * value returned previously by %ETHTOOL_GLINKSETTINGS, otherwise
1944 * refused. For drivers: ignore this field (use kernel's
1945 * __ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will
1946 * be overwritten by kernel.
1947 * @supported: Bitmap with each bit meaning given by
1948 * %ethtool_link_mode_bit_indices for the link modes, physical
1949 * connectors and other link features for which the interface
1950 * supports autonegotiation or auto-detection. Read-only.
1951 * @advertising: Bitmap with each bit meaning given by
1952 * %ethtool_link_mode_bit_indices for the link modes, physical
1953 * connectors and other link features that are advertised through
1954 * autonegotiation or enabled for auto-detection.
1955 * @lp_advertising: Bitmap with each bit meaning given by
1956 * %ethtool_link_mode_bit_indices for the link modes, and other
1957 * link features that the link partner advertised through
1958 * autonegotiation; 0 if unknown or not applicable. Read-only.
1959 * @transceiver: Used to distinguish different possible PHY types,
1960 * reported consistently by PHYLIB. Read-only.
1961 *
1962 * If autonegotiation is disabled, the speed and @duplex represent the
1963 * fixed link mode and are writable if the driver supports multiple
1964 * link modes. If it is enabled then they are read-only; if the link
1965 * is up they represent the negotiated link mode; if the link is down,
1966 * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
1967 * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
1968 *
1969 * Some hardware interfaces may have multiple PHYs and/or physical
1970 * connectors fitted or do not allow the driver to detect which are
1971 * fitted. For these interfaces @port and/or @phy_address may be
1972 * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
1973 * Otherwise, attempts to write different values may be ignored or
1974 * rejected.
1975 *
1976 * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt
1977 * are not available in %ethtool_link_settings. These fields will be
1978 * always set to zero in %ETHTOOL_GSET reply and %ETHTOOL_SSET will
1979 * fail if any of them is set to non-zero value.
1980 *
1981 * Users should assume that all fields not marked read-only are
1982 * writable and subject to validation by the driver. They should use
1983 * %ETHTOOL_GLINKSETTINGS to get the current values before making specific
1984 * changes and then applying them with %ETHTOOL_SLINKSETTINGS.
1985 *
1986 * Drivers that implement %get_link_ksettings and/or
1987 * %set_link_ksettings should ignore the @cmd
1988 * and @link_mode_masks_nwords fields (any change to them overwritten
1989 * by kernel), and rely only on kernel's internal
1990 * %__ETHTOOL_LINK_MODE_MASK_NBITS and
1991 * %ethtool_link_mode_mask_t. Drivers that implement
1992 * %set_link_ksettings() should validate all fields other than @cmd
1993 * and @link_mode_masks_nwords that are not described as read-only or
1994 * deprecated, and must ignore all fields described as read-only.
