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

431 * @pkt_rate_low (both measured in packets per second) the
432 * normal {rx,tx}_* coalescing parameters are used.

1742 * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
1743 * applicable. For clause 45 PHYs this is the PRTAD.

1760 * (>= 0); on return, if handshake in progress, negative if

1768 * refused. For drivers: ignore this field (use kernel's
1769 * __ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will
1770 * be overwritten by kernel.
1771 * @supported: Bitmap with each bit meaning given by
1772 * %ethtool_link_mode_bit_indices for the link modes, physical
1773 * connectors and other link features for which the interface
1774 * supports autonegotiation or auto-detection. Read-only.
1775 * @advertising: Bitmap with each bit meaning given by
1776 * %ethtool_link_mode_bit_indices for the link modes, physical
1777 * connectors and other link features that are advertised through
1778 * autonegotiation or enabled for auto-detection.
1779 * @lp_advertising: Bitmap with each bit meaning given by
1780 * %ethtool_link_mode_bit_indices for the link modes, and other
1781 * link features that the link partner advertised through
1782 * autonegotiation; 0 if unknown or not applicable. Read-only.
1783 * @transceiver: Used to distinguish different possible PHY types,
1784 * reported consistently by PHYLIB. Read-only.
1786 * If autonegotiation is disabled, the speed and @duplex represent the
1787 * fixed link mode and are writable if the driver supports multiple
1788 * link modes. If it is enabled then they are read-only; if the link
1789 * is up they represent the negotiated link mode; if the link is down,
1790 * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
1791 * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
1793 * Some hardware interfaces may have multiple PHYs and/or physical
1794 * connectors fitted or do not allow the driver to detect which are
1795 * fitted. For these interfaces @port and/or @phy_address may be
1796 * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
1797 * Otherwise, attempts to write different values may be ignored or
1800 * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt
1801 * are not available in %ethtool_link_settings. Until all drivers are
1802 * converted to ignore them or to the new %ethtool_link_settings API,
1803 * for both queries and changes, users should always try
1804 * %ETHTOOL_GLINKSETTINGS first, and if it fails with -ENOTSUPP stick
1805 * only to %ETHTOOL_GSET and %ETHTOOL_SSET consistently. If it
1806 * succeeds, then users should stick to %ETHTOOL_GLINKSETTINGS and
1807 * %ETHTOOL_SLINKSETTINGS (which would support drivers implementing
1808 * either %ethtool_cmd or %ethtool_link_settings).
1810 * Users should assume that all fields not marked read-only are
1811 * writable and subject to validation by the driver. They should use
1812 * %ETHTOOL_GLINKSETTINGS to get the current values before making specific
1813 * changes and then applying them with %ETHTOOL_SLINKSETTINGS.
1815 * Drivers that implement %get_link_ksettings and/or
1816 * %set_link_ksettings should ignore the @cmd
1817 * and @link_mode_masks_nwords fields (any change to them overwritten
1818 * by kernel), and rely only on kernel's internal
1819 * %__ETHTOOL_LINK_MODE_MASK_NBITS and
1820 * %ethtool_link_mode_mask_t. Drivers that implement
1821 * %set_link_ksettings() should validate all fields other than @cmd
1822 * and @link_mode_masks_nwords that are not described as read-only or
1823 * deprecated, and must ignore all fields described as read-only.
