30 | * struct ethtool_cmd - DEPRECATED, link control and status | |
31 | * This structure is DEPRECATED, please use struct ethtool_link_settings. | |
32 | * @cmd: Command number = %ETHTOOL_GSET or %ETHTOOL_SSET | |
33 | * @supported: Bitmask of %SUPPORTED_* flags for the link modes, | |
34 | * physical connectors and other link features for which the | |
35 | * interface supports autonegotiation or auto-detection. | |
36 | * Read-only. | |
37 | * @advertising: Bitmask of %ADVERTISED_* flags for the link modes, | |
38 | * physical connectors and other link features that are | |
39 | * advertised through autonegotiation or enabled for | |
40 | * auto-detection. | |
41 | * @speed: Low bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN | |
42 | * @duplex: Duplex mode; one of %DUPLEX_* | |
43 | * @port: Physical connector type; one of %PORT_* | |
44 | * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not | |
45 | * applicable. For clause 45 PHYs this is the PRTAD. | |
46 | * @transceiver: Historically used to distinguish different possible | |
47 | * PHY types, but not in a consistent way. Deprecated. | |
48 | * @autoneg: Enable/disable autonegotiation and auto-detection; | |
49 | * either %AUTONEG_DISABLE or %AUTONEG_ENABLE | |
50 | * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO | |
51 | * protocols supported by the interface; 0 if unknown. | |
52 | * Read-only. | |
53 | * @maxtxpkt: Historically used to report TX IRQ coalescing; now | |
54 | * obsoleted by &struct ethtool_coalesce. Read-only; deprecated. | |
55 | * @maxrxpkt: Historically used to report RX IRQ coalescing; now | |
56 | * obsoleted by &struct ethtool_coalesce. Read-only; deprecated. | |
57 | * @speed_hi: High bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN | |
58 | * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of | |
59 | * %ETH_TP_MDI_*. If the status is unknown or not applicable, the | |
60 | * value will be %ETH_TP_MDI_INVALID. Read-only. | |
61 | * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of | |
62 | * %ETH_TP_MDI_*. If MDI(-X) control is not implemented, reads | |
63 | * yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected. | |
64 | * When written successfully, the link should be renegotiated if | |
65 | * necessary. | |
66 | * @lp_advertising: Bitmask of %ADVERTISED_* flags for the link modes | |
67 | * and other link features that the link partner advertised | |
68 | * through autonegotiation; 0 if unknown or not applicable. | |
69 | * Read-only. | |
70 | * | |
71 | * The link speed in Mbps is split between @speed and @speed_hi. Use | |
72 | * the ethtool_cmd_speed() and ethtool_cmd_speed_set() functions to | |
73 | * access it. | |
74 | * | |
75 | * If autonegotiation is disabled, the speed and @duplex represent the | |
76 | * fixed link mode and are writable if the driver supports multiple | |
77 | * link modes. If it is enabled then they are read-only; if the link | |
78 | * is up they represent the negotiated link mode; if the link is down, | |
79 | * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and | |
80 | * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode. | |
81 | * | |
82 | * Some hardware interfaces may have multiple PHYs and/or physical | |
83 | * connectors fitted or do not allow the driver to detect which are | |
84 | * fitted. For these interfaces @port and/or @phy_address may be | |
85 | * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE. | |
86 | * Otherwise, attempts to write different values may be ignored or | |
87 | * rejected. | |
88 | * | |
89 | * Users should assume that all fields not marked read-only are | |
90 | * writable and subject to validation by the driver. They should use | |
91 | * %ETHTOOL_GSET to get the current values before making specific | |
92 | * changes and then applying them with %ETHTOOL_SSET. | |
93 | * | |
d3b7b374 JB |
94 | * Deprecated fields should be ignored by both users and drivers. |

417 | * (usecs > 0 && time_since_first_completion >= usecs) || | |
418 | * (max_frames > 0 && completed_frames >= max_frames) | |
419 | * | |

432 | * throughput under high packet rates. Some drivers only implement | |
433 | * one of RX or TX adaptive coalescing. Anything not implemented by | |
434 | * the driver causes these values to be silently ignored. | |

1819 | * Some hardware interfaces may have multiple PHYs and/or physical | |
1820 | * connectors fitted or do not allow the driver to detect which are | |
1821 | * fitted. For these interfaces @port and/or @phy_address may be | |
1822 | * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE. | |
1823 | * Otherwise, attempts to write different values may be ignored or | |
1824 | * rejected. | |

1826 | * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt | |
da054c64 PB |
1827 | * are not available in %ethtool_link_settings. These fields will be |
1828 | * always set to zero in %ETHTOOL_GSET reply and %ETHTOOL_SSET will | |
1829 | * fail if any of them is set to non-zero value. | |

1831 | * Users should assume that all fields not marked read-only are | |
1832 | * writable and subject to validation by the driver. They should use | |
1833 | * %ETHTOOL_GLINKSETTINGS to get the current values before making specific | |
1834 | * changes and then applying them with %ETHTOOL_SLINKSETTINGS. | |
1835 | * | |
1836 | * Drivers that implement %get_link_ksettings and/or | |
1837 | * %set_link_ksettings should ignore the @cmd | |
1838 | * and @link_mode_masks_nwords fields (any change to them overwritten | |
1839 | * by kernel), and rely only on kernel's internal | |
1840 | * %__ETHTOOL_LINK_MODE_MASK_NBITS and | |
1841 | * %ethtool_link_mode_mask_t. Drivers that implement | |
1842 | * %set_link_ksettings() should validate all fields other than @cmd | |
1843 | * and @link_mode_masks_nwords that are not described as read-only or | |
1844 | * deprecated, and must ignore all fields described as read-only. | |
