38 * struct ethtool_cmd - DEPRECATED, link control and status
39 * This structure is DEPRECATED, please use struct ethtool_link_settings.
40 * @cmd: Command number = %ETHTOOL_GSET or %ETHTOOL_SSET
41 * @supported: Bitmask of %SUPPORTED_* flags for the link modes,
42 * physical connectors and other link features for which the
43 * interface supports autonegotiation or auto-detection.
44 * Read-only.
45 * @advertising: Bitmask of %ADVERTISED_* flags for the link modes,
46 * physical connectors and other link features that are
47 * advertised through autonegotiation or enabled for
48 * auto-detection.
49 * @speed: Low bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
50 * @duplex: Duplex mode; one of %DUPLEX_*
51 * @port: Physical connector type; one of %PORT_*
52 * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
53 * applicable. For clause 45 PHYs this is the PRTAD.
54 * @transceiver: Historically used to distinguish different possible
55 * PHY types, but not in a consistent way. Deprecated.
56 * @autoneg: Enable/disable autonegotiation and auto-detection;
57 * either %AUTONEG_DISABLE or %AUTONEG_ENABLE
58 * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO
59 * protocols supported by the interface; 0 if unknown.
60 * Read-only.
61 * @maxtxpkt: Historically used to report TX IRQ coalescing; now
62 * obsoleted by &struct ethtool_coalesce. Read-only; deprecated.
63 * @maxrxpkt: Historically used to report RX IRQ coalescing; now
64 * obsoleted by &struct ethtool_coalesce. Read-only; deprecated.
65 * @speed_hi: High bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
66 * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
67 * %ETH_TP_MDI_*. If the status is unknown or not applicable, the
68 * value will be %ETH_TP_MDI_INVALID. Read-only.
69 * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
70 * %ETH_TP_MDI_*. If MDI(-X) control is not implemented, reads
71 * yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
72 * When written successfully, the link should be renegotiated if
73 * necessary.
74 * @lp_advertising: Bitmask of %ADVERTISED_* flags for the link modes
75 * and other link features that the link partner advertised
76 * through autonegotiation; 0 if unknown or not applicable.
77 * Read-only.
78 * @reserved: Reserved for future use; see the note on reserved space.
79 *
80 * The link speed in Mbps is split between @speed and @speed_hi. Use
81 * the ethtool_cmd_speed() and ethtool_cmd_speed_set() functions to
82 * access it.
83 *
84 * If autonegotiation is disabled, the speed and @duplex represent the
85 * fixed link mode and are writable if the driver supports multiple
86 * link modes. If it is enabled then they are read-only; if the link
87 * is up they represent the negotiated link mode; if the link is down,
88 * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
89 * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
90 *
91 * Some hardware interfaces may have multiple PHYs and/or physical
92 * connectors fitted or do not allow the driver to detect which are
93 * fitted. For these interfaces @port and/or @phy_address may be
94 * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
95 * Otherwise, attempts to write different values may be ignored or
96 * rejected.
97 *
98 * Users should assume that all fields not marked read-only are
99 * writable and subject to validation by the driver. They should use
100 * %ETHTOOL_GSET to get the current values before making specific
101 * changes and then applying them with %ETHTOOL_SSET.
102 *
103 * Deprecated fields should be ignored by both users and drivers.

1033 * @cmd: Specific command number - %ETHTOOL_GRXFH, %ETHTOOL_SRXFH,
1034 * %ETHTOOL_GRXRINGS, %ETHTOOL_GRXCLSRLCNT, %ETHTOOL_GRXCLSRULE,
1035 * %ETHTOOL_GRXCLSRLALL, %ETHTOOL_SRXCLSRLDEL or %ETHTOOL_SRXCLSRLINS
1036 * @flow_type: Type of flow to be affected, e.g. %TCP_V4_FLOW
1037 * @data: Command-dependent value
1038 * @fs: Flow classification rule
1039 * @rss_context: RSS context to be affected
1040 * @rule_cnt: Number of rules to be affected
1041 * @rule_locs: Array of used rule locations
1042 *
1043 * For %ETHTOOL_GRXFH and %ETHTOOL_SRXFH, @data is a bitmask indicating
1044 * the fields included in the flow hash, e.g. %RXH_IP_SRC. The following
1045 * structure fields must not be used, except that if @flow_type includes
1046 * the %FLOW_RSS flag, then @rss_context determines which RSS context to
1047 * act on.
1048 *
1049 * For %ETHTOOL_GRXRINGS, @data is set to the number of RX rings/queues
1050 * on return.
1051 *
1052 * For %ETHTOOL_GRXCLSRLCNT, @rule_cnt is set to the number of defined
1053 * rules on return. If @data is non-zero on return then it is the
1054 * size of the rule table, plus the flag %RX_CLS_LOC_SPECIAL if the
1055 * driver supports any special location values. If that flag is not
1056 * set in @data then special location values should not be used.
1057 *
1058 * For %ETHTOOL_GRXCLSRULE, @fs.@location specifies the location of an
1059 * existing rule on entry and @fs contains the rule on return; if
1060 * @fs.@flow_type includes the %FLOW_RSS flag, then @rss_context is
1061 * filled with the RSS context ID associated with the rule.
1062 *
1063 * For %ETHTOOL_GRXCLSRLALL, @rule_cnt specifies the array size of the
1064 * user buffer for @rule_locs on entry. On return, @data is the size
1065 * of the rule table, @rule_cnt is the number of defined rules, and
1066 * @rule_locs contains the locations of the defined rules. Drivers
1067 * must use the second parameter to get_rxnfc() instead of @rule_locs.
1068 *
1069 * For %ETHTOOL_SRXCLSRLINS, @fs specifies the rule to add or update.
1070 * @fs.@location either specifies the location to use or is a special
1071 * location value with %RX_CLS_LOC_SPECIAL flag set. On return,
1072 * @fs.@location is the actual rule location. If @fs.@flow_type
1073 * includes the %FLOW_RSS flag, @rss_context is the RSS context ID to
1074 * use for flow spreading traffic which matches this rule. The value
1075 * from the rxfh indirection table will be added to @fs.@ring_cookie
1076 * to choose which ring to deliver to.
1077 *
1078 * For %ETHTOOL_SRXCLSRLDEL, @fs.@location specifies the location of an
1079 * existing rule on entry.
1080 *
1081 * A driver supporting the special location values for
1082 * %ETHTOOL_SRXCLSRLINS may add the rule at any suitable unused
1083 * location, and may remove a rule at a later location (lower
1084 * priority) that matches exactly the same set of flows. The special
1085 * values are %RX_CLS_LOC_ANY, selecting any location;
1086 * %RX_CLS_LOC_FIRST, selecting the first suitable location (maximum
1087 * priority); and %RX_CLS_LOC_LAST, selecting the last suitable
1088 * location (minimum priority). Additional special values may be
1089 * defined in future and drivers must return -%EINVAL for any
1090 * unrecognised value.

1920 *
1921 * @cmd: Command number = %ETHTOOL_GLINKSETTINGS or %ETHTOOL_SLINKSETTINGS
1922 * @speed: Link speed (Mbps)
1923 * @duplex: Duplex mode; one of %DUPLEX_*
1924 * @port: Physical connector type; one of %PORT_*
1925 * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
1926 * applicable. For clause 45 PHYs this is the PRTAD.
1927 * @autoneg: Enable/disable autonegotiation and auto-detection;
1928 * either %AUTONEG_DISABLE or %AUTONEG_ENABLE
1929 * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO
1930 * protocols supported by the interface; 0 if unknown.
1931 * Read-only.
1932 * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
1933 * %ETH_TP_MDI_*. If the status is unknown or not applicable, the
1934 * value will be %ETH_TP_MDI_INVALID. Read-only.
1935 * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
1936 * %ETH_TP_MDI_*. If MDI(-X) control is not implemented, reads
1937 * yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
1938 * When written successfully, the link should be renegotiated if
1939 * necessary.
1940 * @link_mode_masks_nwords: Number of 32-bit words for each of the
1941 * supported, advertising, lp_advertising link mode bitmaps. For
1942 * %ETHTOOL_GLINKSETTINGS: on entry, number of words passed by user
1943 * (>= 0); on return, if handshake in progress, negative if
1944 * request size unsupported by kernel: absolute value indicates
1945 * kernel expected size and all the other fields but cmd
1946 * are 0; otherwise (handshake completed), strictly positive
1947 * to indicate size used by kernel and cmd field stays
1948 * %ETHTOOL_GLINKSETTINGS, all other fields populated by driver. For
1949 * %ETHTOOL_SLINKSETTINGS: must be valid on entry, ie. a positive
1950 * value returned previously by %ETHTOOL_GLINKSETTINGS, otherwise
1951 * refused. For drivers: ignore this field (use kernel's
1952 * __ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will
1953 * be overwritten by kernel.
1954 * @supported: Bitmap with each bit meaning given by
1955 * %ethtool_link_mode_bit_indices for the link modes, physical
1956 * connectors and other link features for which the interface
1957 * supports autonegotiation or auto-detection. Read-only.
1958 * @advertising: Bitmap with each bit meaning given by
1959 * %ethtool_link_mode_bit_indices for the link modes, physical
1960 * connectors and other link features that are advertised through
1961 * autonegotiation or enabled for auto-detection.
1962 * @lp_advertising: Bitmap with each bit meaning given by
1963 * %ethtool_link_mode_bit_indices for the link modes, and other
1964 * link features that the link partner advertised through
1965 * autonegotiation; 0 if unknown or not applicable. Read-only.
1966 * @transceiver: Used to distinguish different possible PHY types,
1967 * reported consistently by PHYLIB. Read-only.
1968 * @master_slave_cfg: Master/slave port mode.
1969 * @master_slave_state: Master/slave port state.
1970 * @reserved: Reserved for future use; see the note on reserved space.
1971 * @reserved1: Reserved for future use; see the note on reserved space.
1972 * @link_mode_masks: Variable length bitmaps.
1973 *
1974 * If autonegotiation is disabled, the speed and @duplex represent the
1975 * fixed link mode and are writable if the driver supports multiple
1976 * link modes. If it is enabled then they are read-only; if the link
1977 * is up they represent the negotiated link mode; if the link is down,
1978 * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
1979 * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
1980 *
1981 * Some hardware interfaces may have multiple PHYs and/or physical
1982 * connectors fitted or do not allow the driver to detect which are
1983 * fitted. For these interfaces @port and/or @phy_address may be
1984 * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
1985 * Otherwise, attempts to write different values may be ignored or
1986 * rejected.
1987 *
1988 * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt
1989 * are not available in %ethtool_link_settings. These fields will be
1990 * always set to zero in %ETHTOOL_GSET reply and %ETHTOOL_SSET will
1991 * fail if any of them is set to non-zero value.
1992 *
1993 * Users should assume that all fields not marked read-only are
1994 * writable and subject to validation by the driver. They should use
1995 * %ETHTOOL_GLINKSETTINGS to get the current values before making specific
1996 * changes and then applying them with %ETHTOOL_SLINKSETTINGS.
1997 *
1998 * Drivers that implement %get_link_ksettings and/or
1999 * %set_link_ksettings should ignore the @cmd

2002 * %__ETHTOOL_LINK_MODE_MASK_NBITS and
2003 * %ethtool_link_mode_mask_t. Drivers that implement
2004 * %set_link_ksettings() should validate all fields other than @cmd
2005 * and @link_mode_masks_nwords that are not described as read-only or
2006 * deprecated, and must ignore all fields described as read-only.
