|
|
* auto-detection.
|
|
* @speed: Low bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
|
|
* @duplex: Duplex mode; one of %DUPLEX_*
|
|
* @port: Physical connector type; one of %PORT_*
|
|
* @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
|
|
* applicable. For clause 45 PHYs this is the PRTAD.
|
|
* @transceiver: Historically used to distinguish different possible
|
|
* PHY types, but not in a consistent way. Deprecated.
|
|
* @autoneg: Enable/disable autonegotiation and auto-detection;
|
|
* either %AUTONEG_DISABLE or %AUTONEG_ENABLE
|
|
* @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO

|
|
* @speed_hi: High bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
|
|
* @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
|
|
* %ETH_TP_MDI_*. If the status is unknown or not applicable, the
|
|
* value will be %ETH_TP_MDI_INVALID. Read-only.
|
|
* @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
|
|
* %ETH_TP_MDI_*. If MDI(-X) control is not implemented, reads
|
|
* yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
|
|
* When written successfully, the link should be renegotiated if
|
|
* necessary.
|
|
* @lp_advertising: Bitmask of %ADVERTISED_* flags for the link modes
|
|
* and other link features that the link partner advertised
|
|
* through autonegotiation; 0 if unknown or not applicable.
|
|
* Read-only.
|
|
*
|
|
* The link speed in Mbps is split between @speed and @speed_hi. Use
|
|
* the ethtool_cmd_speed() and ethtool_cmd_speed_set() functions to
|
|
* access it.
|
|
*
|
|
* If autonegotiation is disabled, the speed and @duplex represent the
|
|
* fixed link mode and are writable if the driver supports multiple
|
|
* link modes. If it is enabled then they are read-only; if the link
|
|
* is up they represent the negotiated link mode; if the link is down,
|
|
* the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
|
|
* @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
|
|
*
|
|
* Some hardware interfaces may have multiple PHYs and/or physical
|
|
* connectors fitted or do not allow the driver to detect which are
|
|
* fitted. For these interfaces @port and/or @phy_address may be
|
|
* writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
|
|
* Otherwise, attempts to write different values may be ignored or
|
|
* rejected.
|
|
*
|
|
* Users should assume that all fields not marked read-only are
|
|
* writable and subject to validation by the driver. They should use
|
|
* %ETHTOOL_GSET to get the current values before making specific

* struct ethtool_rxnfc - command to get or set RX flow classification rules
|
|
* @cmd: Specific command number - %ETHTOOL_GRXFH, %ETHTOOL_SRXFH,
|
|
* %ETHTOOL_GRXRINGS, %ETHTOOL_GRXCLSRLCNT, %ETHTOOL_GRXCLSRULE,
|
|
* %ETHTOOL_GRXCLSRLALL, %ETHTOOL_SRXCLSRLDEL or %ETHTOOL_SRXCLSRLINS
|
|
* @flow_type: Type of flow to be affected, e.g. %TCP_V4_FLOW
|
|
* @data: Command-dependent value
|
|
* @fs: Flow classification rule
|
|
* @rss_context: RSS context to be affected
|
|
* @rule_cnt: Number of rules to be affected
|
|
* @rule_locs: Array of used rule locations
|
|
*
|
|
* For %ETHTOOL_GRXFH and %ETHTOOL_SRXFH, @data is a bitmask indicating
|
|
* the fields included in the flow hash, e.g. %RXH_IP_SRC. The following
|
|
* structure fields must not be used, except that if @flow_type includes
|
|
* the %FLOW_RSS flag, then @rss_context determines which RSS context to
|
|
* act on.
|
|
*
|
|
* For %ETHTOOL_GRXRINGS, @data is set to the number of RX rings/queues
|
|
* on return.
|
|
*
|
|
* For %ETHTOOL_GRXCLSRLCNT, @rule_cnt is set to the number of defined
|
|
* rules on return. If @data is non-zero on return then it is the
|
|
* size of the rule table, plus the flag %RX_CLS_LOC_SPECIAL if the
|
|
* driver supports any special location values. If that flag is not
|
|
* set in @data then special location values should not be used.
|
|
*
|
|
* For %ETHTOOL_GRXCLSRULE, @fs.@location specifies the location of an
|
|
* existing rule on entry and @fs contains the rule on return; if
|
|
* @fs.@flow_type includes the %FLOW_RSS flag, then @rss_context is
|
|
* filled with the RSS context ID associated with the rule.
|
|
*
|
|
* For %ETHTOOL_GRXCLSRLALL, @rule_cnt specifies the array size of the
|
|
* user buffer for @rule_locs on entry. On return, @data is the size
|
|
* of the rule table, @rule_cnt is the number of defined rules, and
|
|
* @rule_locs contains the locations of the defined rules. Drivers
|
|
* must use the second parameter to get_rxnfc() instead of @rule_locs.
|
|
*
|
|
* For %ETHTOOL_SRXCLSRLINS, @fs specifies the rule to add or update.
|
|
* @fs.@location either specifies the location to use or is a special
|
|
* location value with %RX_CLS_LOC_SPECIAL flag set. On return,
|
|
* @fs.@location is the actual rule location. If @fs.@flow_type
|
|
* includes the %FLOW_RSS flag, @rss_context is the RSS context ID to
|
|
* use for flow spreading traffic which matches this rule. The value
|
|
* from the rxfh indirection table will be added to @fs.@ring_cookie
|
|
* to choose which ring to deliver to.
|
|
*
|
|
* For %ETHTOOL_SRXCLSRLDEL, @fs.@location specifies the location of an
|
|
* existing rule on entry.
|
|
*
|
|
* A driver supporting the special location values for
|
|
* %ETHTOOL_SRXCLSRLINS may add the rule at any suitable unused
|
|
* location, and may remove a rule at a later location (lower
|
|
* priority) that matches exactly the same set of flows. The special
|
|
* values are %RX_CLS_LOC_ANY, selecting any location;
|
|
* %RX_CLS_LOC_FIRST, selecting the first suitable location (maximum
|
|
* priority); and %RX_CLS_LOC_LAST, selecting the last suitable
|
|
* location (minimum priority). Additional special values may be
|
|
* defined in future and drivers must return -%EINVAL for any
|
|
* unrecognised value.

* struct ethtool_link_settings - link control and status
|
|
*
|
|
* IMPORTANT, Backward compatibility notice: When implementing new
|
|
* user-space tools, please first try %ETHTOOL_GLINKSETTINGS, and
|
|
* if it succeeds use %ETHTOOL_SLINKSETTINGS to change link
|
|
* settings; do not use %ETHTOOL_SSET if %ETHTOOL_GLINKSETTINGS
|
|
* succeeded: stick to %ETHTOOL_GLINKSETTINGS/%SLINKSETTINGS in
|
|
* that case. Conversely, if %ETHTOOL_GLINKSETTINGS fails, use
|
|
* %ETHTOOL_GSET to query and %ETHTOOL_SSET to change link
|
|
* settings; do not use %ETHTOOL_SLINKSETTINGS if
|
|
* %ETHTOOL_GLINKSETTINGS failed: stick to
|
|
* %ETHTOOL_GSET/%ETHTOOL_SSET in that case.
|
|
*
|
|
* @cmd: Command number = %ETHTOOL_GLINKSETTINGS or %ETHTOOL_SLINKSETTINGS
|
|
* @speed: Link speed (Mbps)
|
|
* @duplex: Duplex mode; one of %DUPLEX_*
|
|
* @port: Physical connector type; one of %PORT_*
|
|
* @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
|
|
* applicable. For clause 45 PHYs this is the PRTAD.
|
|
* @autoneg: Enable/disable autonegotiation and auto-detection;
|
|
* either %AUTONEG_DISABLE or %AUTONEG_ENABLE
|
|
* @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO
|
|
* protocols supported by the interface; 0 if unknown.
|
|
* Read-only.
|
|
* @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
|
|
* %ETH_TP_MDI_*. If the status is unknown or not applicable, the
|
|
* value will be %ETH_TP_MDI_INVALID. Read-only.
|
|
* @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
|
|
* %ETH_TP_MDI_*. If MDI(-X) control is not implemented, reads
|
|
* yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
|
|
* When written successfully, the link should be renegotiated if
|
|
* necessary.
|
|
* @link_mode_masks_nwords: Number of 32-bit words for each of the
|
|
* supported, advertising, lp_advertising link mode bitmaps. For
|
|
* %ETHTOOL_GLINKSETTINGS: on entry, number of words passed by user
|
|
* (>= 0); on return, if handshake in progress, negative if
|
|
* request size unsupported by kernel: absolute value indicates
|
|
* kernel expected size and all the other fields but cmd
|
|
* are 0; otherwise (handshake completed), strictly positive
|
|
* to indicate size used by kernel and cmd field stays
|
|
* %ETHTOOL_GLINKSETTINGS, all other fields populated by driver. For
|
|
* %ETHTOOL_SLINKSETTINGS: must be valid on entry, ie. a positive
|
|
* value returned previously by %ETHTOOL_GLINKSETTINGS, otherwise
|
|
* refused. For drivers: ignore this field (use kernel's
|
|
* __ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will
|
|
* be overwritten by kernel.
|
|
* @supported: Bitmap with each bit meaning given by
|
|
* %ethtool_link_mode_bit_indices for the link modes, physical
|
|
* connectors and other link features for which the interface
|
|
* supports autonegotiation or auto-detection. Read-only.
|
|
* @advertising: Bitmap with each bit meaning given by
|
|
* %ethtool_link_mode_bit_indices for the link modes, physical
|
|
* connectors and other link features that are advertised through
|
|
* autonegotiation or enabled for auto-detection.
|
|
* @lp_advertising: Bitmap with each bit meaning given by
|
|
* %ethtool_link_mode_bit_indices for the link modes, and other
|
|
* link features that the link partner advertised through
|
|
* autonegotiation; 0 if unknown or not applicable. Read-only.
|
|
* @transceiver: Used to distinguish different possible PHY types,
|
|
* reported consistently by PHYLIB. Read-only.
|
|
*
|
|
* If autonegotiation is disabled, the speed and @duplex represent the
|
|
* fixed link mode and are writable if the driver supports multiple
|
|
* link modes. If it is enabled then they are read-only; if the link
|
|
* is up they represent the negotiated link mode; if the link is down,
|
|
* the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
|
|
* @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
|
|
*
|
|
* Some hardware interfaces may have multiple PHYs and/or physical
|
|
* connectors fitted or do not allow the driver to detect which are
|
|
* fitted. For these interfaces @port and/or @phy_address may be
|
|
* writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
|
|
* Otherwise, attempts to write different values may be ignored or
|
|
* rejected.
|
|
*
|
|
* Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt
|
|
* are not available in %ethtool_link_settings. These fields will be
|
|
* always set to zero in %ETHTOOL_GSET reply and %ETHTOOL_SSET will
|
|
* fail if any of them is set to non-zero value.
|
|
*
|
|
* Users should assume that all fields not marked read-only are
|
|
* writable and subject to validation by the driver. They should use
|
|
* %ETHTOOL_GLINKSETTINGS to get the current values before making specific
|
|
* changes and then applying them with %ETHTOOL_SLINKSETTINGS.
|
|
*
|
|
* Drivers that implement %get_link_ksettings and/or
|
|
* %set_link_ksettings should ignore the @cmd
|
|
* and @link_mode_masks_nwords fields (any change to them overwritten
|
|
* by kernel), and rely only on kernel's internal
|
|
* %__ETHTOOL_LINK_MODE_MASK_NBITS and
|
|
* %ethtool_link_mode_mask_t. Drivers that implement
|
|
* %set_link_ksettings() should validate all fields other than @cmd
|
|
* and @link_mode_masks_nwords that are not described as read-only or
|
|
* deprecated, and must ignore all fields described as read-only.
