| 48 | * physical connectors and other link features that are | |
| 49 | * advertised through autonegotiation or enabled for | |
| 50 | * auto-detection. | |
| 51 | * @speed: Low bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN | |
| 52 | * @duplex: Duplex mode; one of %DUPLEX_* | |
| 53 | * @port: Physical connector type; one of %PORT_* | |
| 54 | * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not | |
| 55 | * applicable. For clause 45 PHYs this is the PRTAD. | |
| 56 | * @transceiver: Historically used to distinguish different possible | |
| 57 | * PHY types, but not in a consistent way. Deprecated. | |
| 58 | * @autoneg: Enable/disable autonegotiation and auto-detection; | |
| 59 | * either %AUTONEG_DISABLE or %AUTONEG_ENABLE | |
| 60 | * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO | |
| 61 | * protocols supported by the interface; 0 if unknown. | |

| 67 | * @speed_hi: High bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN | |
| 68 | * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of | |
| 69 | * %ETH_TP_MDI_*. If the status is unknown or not applicable, the | |
| 70 | * value will be %ETH_TP_MDI_INVALID. Read-only. | |
| 71 | * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of | |
| 72 | * %ETH_TP_MDI_*. If MDI(-X) control is not implemented, reads | |
| 73 | * yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected. | |
| 74 | * When written successfully, the link should be renegotiated if | |
| 75 | * necessary. | |
| 76 | * @lp_advertising: Bitmask of %ADVERTISED_* flags for the link modes | |
| 77 | * and other link features that the link partner advertised | |
| 78 | * through autonegotiation; 0 if unknown or not applicable. | |
| 79 | * Read-only. | |

| 01234e1f YW |
81 | * |
| 82 | * The link speed in Mbps is split between @speed and @speed_hi. Use | |
| 83 | * the ethtool_cmd_speed() and ethtool_cmd_speed_set() functions to | |
| 84 | * access it. | |
| 85 | * | |
| 86 | * If autonegotiation is disabled, the speed and @duplex represent the | |
| 87 | * fixed link mode and are writable if the driver supports multiple | |
| 88 | * link modes. If it is enabled then they are read-only; if the link | |
| 89 | * is up they represent the negotiated link mode; if the link is down, | |
| 90 | * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and | |
| 91 | * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode. | |
| 92 | * | |
| 93 | * Some hardware interfaces may have multiple PHYs and/or physical | |
| 94 | * connectors fitted or do not allow the driver to detect which are | |
| 95 | * fitted. For these interfaces @port and/or @phy_address may be | |
| 96 | * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE. | |
| 97 | * Otherwise, attempts to write different values may be ignored or | |
| 98 | * rejected. | |
| 99 | * | |
| 100 | * Users should assume that all fields not marked read-only are | |
| 101 | * writable and subject to validation by the driver. They should use | |
| 102 | * %ETHTOOL_GSET to get the current values before making specific | |
| 103 | * changes and then applying them with %ETHTOOL_SSET. | |
| 104 | * | |

| 440 | * a packet arrives, when the packet rate is above @pkt_rate_high. | |
| 441 | * @rx_max_coalesced_frames_high: Maximum number of packets to be received | |

| 447 | * @rate_sample_interval: How often to do adaptive coalescing packet rate | |
| 448 | * sampling, measured in seconds. Must not be zero. | |
| 449 | * | |
| 450 | * Each pair of (usecs, max_frames) fields specifies that interrupts | |
| 451 | * should be coalesced until | |
| 452 | * (usecs > 0 && time_since_first_completion >= usecs) || | |
| 453 | * (max_frames > 0 && completed_frames >= max_frames) | |
| 454 | * | |
| 455 | * It is illegal to set both usecs and max_frames to zero as this | |
| 456 | * would cause interrupts to never be generated. To disable | |
| 457 | * coalescing, set usecs = 0 and max_frames = 1. | |
| 458 | * | |
| 459 | * Some implementations ignore the value of max_frames and use the | |
| 460 | * condition time_since_first_completion >= usecs | |
| 461 | * | |
| 462 | * This is deprecated. Drivers for hardware that does not support | |
| 463 | * counting completions should validate that max_frames == !rx_usecs. | |
| 464 | * | |
| 465 | * Adaptive RX/TX coalescing is an algorithm implemented by some | |
| 466 | * drivers to improve latency under low packet rates and improve | |
| 467 | * throughput under high packet rates. Some drivers only implement | |
| 468 | * one of RX or TX adaptive coalescing. Anything not implemented by | |
| 469 | * the driver causes these values to be silently ignored. | |
| 470 | * | |
| 471 | * When the packet rate is below @pkt_rate_high but above | |
| 472 | * @pkt_rate_low (both measured in packets per second) the | |
| 473 | * normal {rx,tx}_* coalescing parameters are used. | |

| 1132 | * structure fields must not be used, except that if @flow_type includes | |
| 1133 | * the %FLOW_RSS flag, then @rss_context determines which RSS context to | |
| 1134 | * act on. | |
| 1135 | * | |
| 1136 | * For %ETHTOOL_GRXRINGS, @data is set to the number of RX rings/queues | |
| 1137 | * on return. | |
| 1138 | * | |
| 1139 | * For %ETHTOOL_GRXCLSRLCNT, @rule_cnt is set to the number of defined | |
| 1140 | * rules on return. If @data is non-zero on return then it is the | |
| 1141 | * size of the rule table, plus the flag %RX_CLS_LOC_SPECIAL if the | |
| 1142 | * driver supports any special location values. If that flag is not | |
| 1143 | * set in @data then special location values should not be used. | |
| 1144 | * | |
| 1145 | * For %ETHTOOL_GRXCLSRULE, @fs.@location specifies the location of an | |
| 1146 | * existing rule on entry and @fs contains the rule on return; if | |
| 1147 | * @fs.@flow_type includes the %FLOW_RSS flag, then @rss_context is | |
| 1148 | * filled with the RSS context ID associated with the rule. | |
| 1149 | * | |
| 1150 | * For %ETHTOOL_GRXCLSRLALL, @rule_cnt specifies the array size of the | |
| 1151 | * user buffer for @rule_locs on entry. On return, @data is the size | |
| 1152 | * of the rule table, @rule_cnt is the number of defined rules, and | |
| 1153 | * @rule_locs contains the locations of the defined rules. Drivers | |
| 1154 | * must use the second parameter to get_rxnfc() instead of @rule_locs. | |
| 1155 | * | |
| 1156 | * For %ETHTOOL_SRXCLSRLINS, @fs specifies the rule to add or update. | |
| 1157 | * @fs.@location either specifies the location to use or is a special | |
| 1158 | * location value with %RX_CLS_LOC_SPECIAL flag set. On return, | |
| 1159 | * @fs.@location is the actual rule location. If @fs.@flow_type | |
| 1160 | * includes the %FLOW_RSS flag, @rss_context is the RSS context ID to | |
| 1161 | * use for flow spreading traffic which matches this rule. The value | |
| 1162 | * from the rxfh indirection table will be added to @fs.@ring_cookie | |
| 1163 | * to choose which ring to deliver to. | |
| 1164 | * | |
| 1165 | * For %ETHTOOL_SRXCLSRLDEL, @fs.@location specifies the location of an | |

| 1167 | * | |
| 1168 | * A driver supporting the special location values for | |
| 1169 | * %ETHTOOL_SRXCLSRLINS may add the rule at any suitable unused | |
| 1170 | * location, and may remove a rule at a later location (lower | |
| 1171 | * priority) that matches exactly the same set of flows. The special | |
| 1172 | * values are %RX_CLS_LOC_ANY, selecting any location; | |
| 1173 | * %RX_CLS_LOC_FIRST, selecting the first suitable location (maximum | |

| 2041 | * struct ethtool_link_settings - link control and status | |
| 2042 | * | |
| 2043 | * IMPORTANT, Backward compatibility notice: When implementing new | |
| 2044 | * user-space tools, please first try %ETHTOOL_GLINKSETTINGS, and | |
| 2045 | * if it succeeds use %ETHTOOL_SLINKSETTINGS to change link | |
| 2046 | * settings; do not use %ETHTOOL_SSET if %ETHTOOL_GLINKSETTINGS | |
| 2047 | * succeeded: stick to %ETHTOOL_GLINKSETTINGS/%SLINKSETTINGS in | |
| 2048 | * that case. Conversely, if %ETHTOOL_GLINKSETTINGS fails, use | |
| 2049 | * %ETHTOOL_GSET to query and %ETHTOOL_SSET to change link | |
| 2050 | * settings; do not use %ETHTOOL_SLINKSETTINGS if | |
| 2051 | * %ETHTOOL_GLINKSETTINGS failed: stick to | |
| 2052 | * %ETHTOOL_GSET/%ETHTOOL_SSET in that case. | |
| 2053 | * | |
| 2054 | * @cmd: Command number = %ETHTOOL_GLINKSETTINGS or %ETHTOOL_SLINKSETTINGS | |
| 2055 | * @speed: Link speed (Mbps) | |
| 2056 | * @duplex: Duplex mode; one of %DUPLEX_* | |
| 2057 | * @port: Physical connector type; one of %PORT_* | |
| 2058 | * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not | |
| 2059 | * applicable. For clause 45 PHYs this is the PRTAD. | |
| 2060 | * @autoneg: Enable/disable autonegotiation and auto-detection; | |
| 2061 | * either %AUTONEG_DISABLE or %AUTONEG_ENABLE | |
| 2062 | * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO | |
| 2063 | * protocols supported by the interface; 0 if unknown. | |
| 2064 | * Read-only. | |
| 2065 | * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of | |
| 2066 | * %ETH_TP_MDI_*. If the status is unknown or not applicable, the | |
| 2067 | * value will be %ETH_TP_MDI_INVALID. Read-only. | |
| 2068 | * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of | |
| 2069 | * %ETH_TP_MDI_*. If MDI(-X) control is not implemented, reads | |
| 2070 | * yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected. | |
| 2071 | * When written successfully, the link should be renegotiated if | |
| 2072 | * necessary. | |
| 2073 | * @link_mode_masks_nwords: Number of 32-bit words for each of the | |
| 2074 | * supported, advertising, lp_advertising link mode bitmaps. For | |
| 2075 | * %ETHTOOL_GLINKSETTINGS: on entry, number of words passed by user | |
| 2076 | * (>= 0); on return, if handshake in progress, negative if | |
| 2077 | * request size unsupported by kernel: absolute value indicates | |
| 2078 | * kernel expected size and all the other fields but cmd | |
| 2079 | * are 0; otherwise (handshake completed), strictly positive | |
| 2080 | * to indicate size used by kernel and cmd field stays | |
| 2081 | * %ETHTOOL_GLINKSETTINGS, all other fields populated by driver. For | |
| 2082 | * %ETHTOOL_SLINKSETTINGS: must be valid on entry, ie. a positive | |
| 2083 | * value returned previously by %ETHTOOL_GLINKSETTINGS, otherwise | |
| 2084 | * refused. For drivers: ignore this field (use kernel's | |
| 2085 | * __ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will | |
| 2086 | * be overwritten by kernel. | |
| 2087 | * @supported: Bitmap with each bit meaning given by | |
| 2088 | * %ethtool_link_mode_bit_indices for the link modes, physical | |
| 2089 | * connectors and other link features for which the interface | |
| 2090 | * supports autonegotiation or auto-detection. Read-only. | |
| 2091 | * @advertising: Bitmap with each bit meaning given by | |
| 2092 | * %ethtool_link_mode_bit_indices for the link modes, physical | |
| 2093 | * connectors and other link features that are advertised through | |
| 2094 | * autonegotiation or enabled for auto-detection. | |
| 2095 | * @lp_advertising: Bitmap with each bit meaning given by | |
| 2096 | * %ethtool_link_mode_bit_indices for the link modes, and other | |
| 2097 | * link features that the link partner advertised through | |
| 2098 | * autonegotiation; 0 if unknown or not applicable. Read-only. | |
| 2099 | * @transceiver: Used to distinguish different possible PHY types, | |
| 2100 | * reported consistently by PHYLIB. Read-only. | |
| 254a7d66 YW |
2101 | * @master_slave_cfg: Master/slave port mode. |
| 2102 | * @master_slave_state: Master/slave port state. | |
| 99d4dfd1 | 2103 | * @rate_matching: Rate adaptation performed by the PHY |
| 254a7d66 | 2104 | * @reserved: Reserved for future use; see the note on reserved space. |
| 254a7d66 | 2105 | * @link_mode_masks: Variable length bitmaps. |
| 01234e1f YW |
2106 | * |
| 2107 | * If autonegotiation is disabled, the speed and @duplex represent the | |
| 2108 | * fixed link mode and are writable if the driver supports multiple | |
| 2109 | * link modes. If it is enabled then they are read-only; if the link | |
| 2110 | * is up they represent the negotiated link mode; if the link is down, | |
| 2111 | * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and | |
| 2112 | * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode. | |
| 2113 | * | |
| 2114 | * Some hardware interfaces may have multiple PHYs and/or physical | |
| 2115 | * connectors fitted or do not allow the driver to detect which are | |
| 2116 | * fitted. For these interfaces @port and/or @phy_address may be | |
| 2117 | * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE. | |
| 2118 | * Otherwise, attempts to write different values may be ignored or | |
| 2119 | * rejected. | |
| 2120 | * | |
| 2121 | * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt | |
| 2122 | * are not available in %ethtool_link_settings. These fields will be | |
| 2123 | * always set to zero in %ETHTOOL_GSET reply and %ETHTOOL_SSET will | |
| 2124 | * fail if any of them is set to non-zero value. | |
| 2125 | * | |
| 2126 | * Users should assume that all fields not marked read-only are | |
| 2127 | * writable and subject to validation by the driver. They should use | |
| 2128 | * %ETHTOOL_GLINKSETTINGS to get the current values before making specific | |
| 2129 | * changes and then applying them with %ETHTOOL_SLINKSETTINGS. | |
| 2130 | * | |
| 2131 | * Drivers that implement %get_link_ksettings and/or | |
| 2132 | * %set_link_ksettings should ignore the @cmd | |
| 2133 | * and @link_mode_masks_nwords fields (any change to them overwritten | |
| 2134 | * by kernel), and rely only on kernel's internal | |
| 2135 | * %__ETHTOOL_LINK_MODE_MASK_NBITS and | |
| 2136 | * %ethtool_link_mode_mask_t. Drivers that implement | |
| 2137 | * %set_link_ksettings() should validate all fields other than @cmd | |
| 2138 | * and @link_mode_masks_nwords that are not described as read-only or | |
| 2139 | * deprecated, and must ignore all fields described as read-only. | |
