  37/**
  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.

 423 *      in-memory statistic block, and in such cases this value is
 424 *      ignored.  This value must not be zero.

 431 *      before an RX interrupt, when the packet rate is below @pkt_rate_low.

 433 *      a packet is sent, when the packet rate is below @pkt_rate_low.
 434 * @tx_max_coalesced_frames_low: Maximum nuumber of packets to be sent before
 435 *      a TX interrupt, when the packet rate is below @pkt_rate_low.
 436 * @pkt_rate_high: Threshold for high packet rate (packets per second).
 437 * @rx_coalesce_usecs_high: How many usecs to delay an RX interrupt after
 438 *      a packet arrives, when the packet rate is above @pkt_rate_high.
 439 * @rx_max_coalesced_frames_high: Maximum number of packets to be received
 440 *      before an RX interrupt, when the packet rate is above @pkt_rate_high.
 441 * @tx_coalesce_usecs_high: How many usecs to delay a TX interrupt after
 442 *      a packet is sent, when the packet rate is above @pkt_rate_high.
 443 * @tx_max_coalesced_frames_high: Maximum number of packets to be sent before
 444 *      a TX interrupt, when the packet rate is above @pkt_rate_high.
 445 * @rate_sample_interval: How often to do adaptive coalescing packet rate
 446 *      sampling, measured in seconds.  Must not be zero.
 447 *
 448 * Each pair of (usecs, max_frames) fields specifies that interrupts
 449 * should be coalesced until
 450 *      (usecs > 0 && time_since_first_completion >= usecs) ||
 451 *      (max_frames > 0 && completed_frames >= max_frames)
 452 *
 453 * It is illegal to set both usecs and max_frames to zero as this
 454 * would cause interrupts to never be generated.  To disable
 455 * coalescing, set usecs = 0 and max_frames = 1.
 456 *
 457 * Some implementations ignore the value of max_frames and use the
 458 * condition time_since_first_completion >= usecs
 459 *
 460 * This is deprecated.  Drivers for hardware that does not support
 461 * counting completions should validate that max_frames == !rx_usecs.
 462 *
 463 * Adaptive RX/TX coalescing is an algorithm implemented by some
 464 * drivers to improve latency under low packet rates and improve
 465 * throughput under high packet rates.  Some drivers only implement
 466 * one of RX or TX adaptive coalescing.  Anything not implemented by
 467 * the driver causes these values to be silently ignored.
 468 *
 469 * When the packet rate is below @pkt_rate_high but above
 470 * @pkt_rate_low (both measured in packets per second) the
 471 * normal {rx,tx}_* coalescing parameters are used.

1175 * act on.
1176 *
1177 * For %ETHTOOL_GRXRINGS, @data is set to the number of RX rings/queues
1178 * on return.
1179 *
1180 * For %ETHTOOL_GRXCLSRLCNT, @rule_cnt is set to the number of defined
1181 * rules on return.  If @data is non-zero on return then it is the
1182 * size of the rule table, plus the flag %RX_CLS_LOC_SPECIAL if the
1183 * driver supports any special location values.  If that flag is not
1184 * set in @data then special location values should not be used.
1185 *
1186 * For %ETHTOOL_GRXCLSRULE, @fs.@location specifies the location of an
1187 * existing rule on entry and @fs contains the rule on return; if
1188 * @fs.@flow_type includes the %FLOW_RSS flag, then @rss_context is
1189 * filled with the RSS context ID associated with the rule.
1190 *
1191 * For %ETHTOOL_GRXCLSRLALL, @rule_cnt specifies the array size of the
1192 * user buffer for @rule_locs on entry.  On return, @data is the size
1193 * of the rule table, @rule_cnt is the number of defined rules, and
1194 * @rule_locs contains the locations of the defined rules.  Drivers
1195 * must use the second parameter to get_rxnfc() instead of @rule_locs.
1196 *
1197 * For %ETHTOOL_SRXCLSRLINS, @fs specifies the rule to add or update.
1198 * @fs.@location either specifies the location to use or is a special
1199 * location value with %RX_CLS_LOC_SPECIAL flag set.  On return,
1200 * @fs.@location is the actual rule location.  If @fs.@flow_type
1201 * includes the %FLOW_RSS flag, @rss_context is the RSS context ID to
1202 * use for flow spreading traffic which matches this rule.  The value
1203 * from the rxfh indirection table will be added to @fs.@ring_cookie
1204 * to choose which ring to deliver to.
1205 *
1206 * For %ETHTOOL_SRXCLSRLDEL, @fs.@location specifies the location of an
1207 * existing rule on entry.
1208 *
1209 * A driver supporting the special location values for
1210 * %ETHTOOL_SRXCLSRLINS may add the rule at any suitable unused
1211 * location, and may remove a rule at a later location (lower
1212 * priority) that matches exactly the same set of flows.  The special
1213 * values are %RX_CLS_LOC_ANY, selecting any location;
1214 * %RX_CLS_LOC_FIRST, selecting the first suitable location (maximum
1215 * priority); and %RX_CLS_LOC_LAST, selecting the last suitable
1216 * location (minimum priority).  Additional special values may be
1217 * defined in future and drivers must return -%EINVAL for any
1218 * unrecognised value.

2085 * struct ethtool_link_settings - link control and status
2086 *
2087 * IMPORTANT, Backward compatibility notice: When implementing new
2088 *      user-space tools, please first try %ETHTOOL_GLINKSETTINGS, and
2089 *      if it succeeds use %ETHTOOL_SLINKSETTINGS to change link
2090 *      settings; do not use %ETHTOOL_SSET if %ETHTOOL_GLINKSETTINGS
2091 *      succeeded: stick to %ETHTOOL_GLINKSETTINGS/%SLINKSETTINGS in
2092 *      that case.  Conversely, if %ETHTOOL_GLINKSETTINGS fails, use
2093 *      %ETHTOOL_GSET to query and %ETHTOOL_SSET to change link
2094 *      settings; do not use %ETHTOOL_SLINKSETTINGS if
2095 *      %ETHTOOL_GLINKSETTINGS failed: stick to
2096 *      %ETHTOOL_GSET/%ETHTOOL_SSET in that case.
2097 *
2098 * @cmd: Command number = %ETHTOOL_GLINKSETTINGS or %ETHTOOL_SLINKSETTINGS
2099 * @speed: Link speed (Mbps)
2100 * @duplex: Duplex mode; one of %DUPLEX_*
2101 * @port: Physical connector type; one of %PORT_*
2102 * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
2103 *      applicable.  For clause 45 PHYs this is the PRTAD.
2104 * @autoneg: Enable/disable autonegotiation and auto-detection;
2105 *      either %AUTONEG_DISABLE or %AUTONEG_ENABLE
2106 * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO
2107 *      protocols supported by the interface; 0 if unknown.
2108 *      Read-only.
2109 * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
2110 *      %ETH_TP_MDI_*.  If the status is unknown or not applicable, the
2111 *      value will be %ETH_TP_MDI_INVALID.  Read-only.
2112 * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
2113 *      %ETH_TP_MDI_*.  If MDI(-X) control is not implemented, reads
2114 *      yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
2115 *      When written successfully, the link should be renegotiated if
2116 *      necessary.
2117 * @link_mode_masks_nwords: Number of 32-bit words for each of the
2118 *      supported, advertising, lp_advertising link mode bitmaps. For
2119 *      %ETHTOOL_GLINKSETTINGS: on entry, number of words passed by user
2120 *      (>= 0); on return, if handshake in progress, negative if
2121 *      request size unsupported by kernel: absolute value indicates
2122 *      kernel expected size and all the other fields but cmd
2123 *      are 0; otherwise (handshake completed), strictly positive
2124 *      to indicate size used by kernel and cmd field stays
2125 *      %ETHTOOL_GLINKSETTINGS, all other fields populated by driver. For
2126 *      %ETHTOOL_SLINKSETTINGS: must be valid on entry, ie. a positive
2127 *      value returned previously by %ETHTOOL_GLINKSETTINGS, otherwise
2128 *      refused. For drivers: ignore this field (use kernel's
2129 *      __ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will
2130 *      be overwritten by kernel.
2131 * @supported: Bitmap with each bit meaning given by
2132 *      %ethtool_link_mode_bit_indices for the link modes, physical
2133 *      connectors and other link features for which the interface
2134 *      supports autonegotiation or auto-detection.  Read-only.
2135 * @advertising: Bitmap with each bit meaning given by
2136 *      %ethtool_link_mode_bit_indices for the link modes, physical
2137 *      connectors and other link features that are advertised through
2138 *      autonegotiation or enabled for auto-detection.
2139 * @lp_advertising: Bitmap with each bit meaning given by
2140 *      %ethtool_link_mode_bit_indices for the link modes, and other
2141 *      link features that the link partner advertised through
2142 *      autonegotiation; 0 if unknown or not applicable.  Read-only.
2143 * @transceiver: Used to distinguish different possible PHY types,
2144 *      reported consistently by PHYLIB.  Read-only.
2145 * @master_slave_cfg: Master/slave port mode.
2146 * @master_slave_state: Master/slave port state.
2147 * @rate_matching: Rate adaptation performed by the PHY
2148 * @reserved: Reserved for future use; see the note on reserved space.
2149 * @link_mode_masks: Variable length bitmaps.
2150 *
2151 * If autonegotiation is disabled, the speed and @duplex represent the
2152 * fixed link mode and are writable if the driver supports multiple
2153 * link modes.  If it is enabled then they are read-only; if the link
2154 * is up they represent the negotiated link mode; if the link is down,
2155 * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
2156 * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
2157 *
2158 * Some hardware interfaces may have multiple PHYs and/or physical
2159 * connectors fitted or do not allow the driver to detect which are
2160 * fitted.  For these interfaces @port and/or @phy_address may be
2161 * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
2162 * Otherwise, attempts to write different values may be ignored or
2163 * rejected.
2164 *
2165 * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt
2166 * are not available in %ethtool_link_settings. These fields will be
2167 * always set to zero in %ETHTOOL_GSET reply and %ETHTOOL_SSET will
2168 * fail if any of them is set to non-zero value.
2169 *
2170 * Users should assume that all fields not marked read-only are
2171 * writable and subject to validation by the driver.  They should use
2172 * %ETHTOOL_GLINKSETTINGS to get the current values before making specific
2173 * changes and then applying them with %ETHTOOL_SLINKSETTINGS.
2174 *
2175 * Drivers that implement %get_link_ksettings and/or
2176 * %set_link_ksettings should ignore the @cmd
2177 * and @link_mode_masks_nwords fields (any change to them overwritten
2178 * by kernel), and rely only on kernel's internal
2179 * %__ETHTOOL_LINK_MODE_MASK_NBITS and
2180 * %ethtool_link_mode_mask_t. Drivers that implement
2181 * %set_link_ksettings() should validate all fields other than @cmd
2182 * and @link_mode_masks_nwords that are not described as read-only or
2183 * deprecated, and must ignore all fields described as read-only.
