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. |

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. |

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. |

2164 | * @autoneg: Enable/disable autonegotiation and auto-detection; |

2167 | * protocols supported by the interface; 0 if unknown. |
2168 | * Read-only. |
2169 | * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of |

2187 | * value returned previously by %ETHTOOL_GLINKSETTINGS, otherwise |
2188 | * refused. For drivers: ignore this field (use kernel's |
2189 | * __ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will |
2190 | * be overwritten by kernel. |
2191 | * @transceiver: Used to distinguish different possible PHY types, |
2192 | * reported consistently by PHYLIB. Read-only. |
2193 | * @master_slave_cfg: Master/slave port mode. |
2194 | * @master_slave_state: Master/slave port state. |
2195 | * @rate_matching: Rate adaptation performed by the PHY |
2196 | * @reserved: Reserved for future use; see the note on reserved space. |
2197 | * @link_mode_masks: Variable length bitmaps. |
2198 | * |
2199 | * If autonegotiation is disabled, the speed and @duplex represent the |
2200 | * fixed link mode and are writable if the driver supports multiple |
2201 | * link modes. If it is enabled then they are read-only; if the link |
2202 | * is up they represent the negotiated link mode; if the link is down, |
2203 | * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and |

2229 | * %set_link_ksettings() should validate all fields other than @cmd |
2230 | * and @link_mode_masks_nwords that are not described as read-only or |
