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. |

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. |

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 |

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. |

1088 | * the %FLOW_RSS flag, then @rss_context determines which RSS context to |
1089 | * act on. |

1097 | * driver supports any special location values. If that flag is not |
1098 | * set in @data then special location values should not be used. |
1099 | * |

1113 | * location value with %RX_CLS_LOC_SPECIAL flag set. On return, |
1114 | * @fs.@location is the actual rule location. If @fs.@flow_type |
1115 | * includes the %FLOW_RSS flag, @rss_context is the RSS context ID to |
1116 | * use for flow spreading traffic which matches this rule. The value |

1974 | * struct ethtool_link_settings - link control and status |
1975 | * |
1976 | * IMPORTANT, Backward compatibility notice: When implementing new |
1977 | * user-space tools, please first try %ETHTOOL_GLINKSETTINGS, and |
1978 | * if it succeeds use %ETHTOOL_SLINKSETTINGS to change link |
1979 | * settings; do not use %ETHTOOL_SSET if %ETHTOOL_GLINKSETTINGS |
1980 | * succeeded: stick to %ETHTOOL_GLINKSETTINGS/%SLINKSETTINGS in |
1981 | * that case. Conversely, if %ETHTOOL_GLINKSETTINGS fails, use |
1982 | * %ETHTOOL_GSET to query and %ETHTOOL_SSET to change link |
1983 | * settings; do not use %ETHTOOL_SLINKSETTINGS if |
1984 | * %ETHTOOL_GLINKSETTINGS failed: stick to |
1985 | * %ETHTOOL_GSET/%ETHTOOL_SSET in that case. |
1986 | * |
1987 | * @cmd: Command number = %ETHTOOL_GLINKSETTINGS or %ETHTOOL_SLINKSETTINGS |
1988 | * @speed: Link speed (Mbps) |
1989 | * @duplex: Duplex mode; one of %DUPLEX_* |
1990 | * @port: Physical connector type; one of %PORT_* |
1991 | * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not |
1992 | * applicable. For clause 45 PHYs this is the PRTAD. |
1993 | * @autoneg: Enable/disable autonegotiation and auto-detection; |
1994 | * either %AUTONEG_DISABLE or %AUTONEG_ENABLE |
1995 | * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO |
1996 | * protocols supported by the interface; 0 if unknown. |
1997 | * Read-only. |
1998 | * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of |
1999 | * %ETH_TP_MDI_*. If the status is unknown or not applicable, the |
2000 | * value will be %ETH_TP_MDI_INVALID. Read-only. |
2001 | * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of |
2002 | * %ETH_TP_MDI_*. If MDI(-X) control is not implemented, reads |
2003 | * yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected. |
2004 | * When written successfully, the link should be renegotiated if |
2005 | * necessary. |
2006 | * @link_mode_masks_nwords: Number of 32-bit words for each of the |
2007 | * supported, advertising, lp_advertising link mode bitmaps. For |
2008 | * %ETHTOOL_GLINKSETTINGS: on entry, number of words passed by user |
2009 | * (>= 0); on return, if handshake in progress, negative if |
2010 | * request size unsupported by kernel: absolute value indicates |
2011 | * kernel expected size and all the other fields but cmd |
2012 | * are 0; otherwise (handshake completed), strictly positive |
2013 | * to indicate size used by kernel and cmd field stays |
2014 | * %ETHTOOL_GLINKSETTINGS, all other fields populated by driver. For |
2015 | * %ETHTOOL_SLINKSETTINGS: must be valid on entry, ie. a positive |
2016 | * value returned previously by %ETHTOOL_GLINKSETTINGS, otherwise |
2017 | * refused. For drivers: ignore this field (use kernel's |
2018 | * __ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will |
2019 | * be overwritten by kernel. |
2020 | * @supported: Bitmap with each bit meaning given by |
2021 | * %ethtool_link_mode_bit_indices for the link modes, physical |
2022 | * connectors and other link features for which the interface |
2023 | * supports autonegotiation or auto-detection. Read-only. |
2024 | * @advertising: Bitmap with each bit meaning given by |
2025 | * %ethtool_link_mode_bit_indices for the link modes, physical |
2026 | * connectors and other link features that are advertised through |
2027 | * autonegotiation or enabled for auto-detection. |
2028 | * @lp_advertising: Bitmap with each bit meaning given by |
2029 | * %ethtool_link_mode_bit_indices for the link modes, and other |
2030 | * link features that the link partner advertised through |
2031 | * autonegotiation; 0 if unknown or not applicable. Read-only. |
2032 | * @transceiver: Used to distinguish different possible PHY types, |
2033 | * reported consistently by PHYLIB. Read-only. |
2034 | * @master_slave_cfg: Master/slave port mode. |
2035 | * @master_slave_state: Master/slave port state. |
2036 | * @reserved: Reserved for future use; see the note on reserved space. |
2037 | * @reserved1: Reserved for future use; see the note on reserved space. |
2038 | * @link_mode_masks: Variable length bitmaps. |
2039 | * |
2040 | * If autonegotiation is disabled, the speed and @duplex represent the |
2041 | * fixed link mode and are writable if the driver supports multiple |
2042 | * link modes. If it is enabled then they are read-only; if the link |
2043 | * is up they represent the negotiated link mode; if the link is down, |
2044 | * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and |
2045 | * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode. |
2046 | * |
2047 | * Some hardware interfaces may have multiple PHYs and/or physical |
2048 | * connectors fitted or do not allow the driver to detect which are |
2049 | * fitted. For these interfaces @port and/or @phy_address may be |
2050 | * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE. |
2051 | * Otherwise, attempts to write different values may be ignored or |
2052 | * rejected. |
2053 | * |
2054 | * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt |
2055 | * are not available in %ethtool_link_settings. These fields will be |
2056 | * always set to zero in %ETHTOOL_GSET reply and %ETHTOOL_SSET will |
2057 | * fail if any of them is set to non-zero value. |
2058 | * |
2059 | * Users should assume that all fields not marked read-only are |
2060 | * writable and subject to validation by the driver. They should use |
2061 | * %ETHTOOL_GLINKSETTINGS to get the current values before making specific |
2062 | * changes and then applying them with %ETHTOOL_SLINKSETTINGS. |
2063 | * |
2064 | * Drivers that implement %get_link_ksettings and/or |
2065 | * %set_link_ksettings should ignore the @cmd |
2066 | * and @link_mode_masks_nwords fields (any change to them overwritten |
2067 | * by kernel), and rely only on kernel's internal |
2068 | * %__ETHTOOL_LINK_MODE_MASK_NBITS and |
2069 | * %ethtool_link_mode_mask_t. Drivers that implement |
2070 | * %set_link_ksettings() should validate all fields other than @cmd |
2071 | * and @link_mode_masks_nwords that are not described as read-only or |
2072 | * deprecated, and must ignore all fields described as read-only. |
