Hi,
Linux can now read linkspeed and duplex settings as set by the
hypervisor:
faa9b39 virtio_net: propagate linkspeed/duplex settings from the hypervisor
This series thus adds qemu support.
Also, this patchset depends on this header sync:
https://lists.gnu.org/archive/html/qemu-devel/2018-02/msg07072.html
Thanks,

A subsequent patch to add support for setting linkspeed/duplex in
virtio-net, requires a few definitions from ethtool.h, which ends up
pulling in kernel.h and sysinfo.h as well.

+ * @port: Physical connector type; one of %PORT_*
+ * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not

+ * @transceiver: Historically used to distinguish different possible
+ * PHY types, but not in a consistent way. Deprecated.

+ * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO

+ * obsoleted by &struct ethtool_coalesce. Read-only; deprecated.

+ * obsoleted by &struct ethtool_coalesce. Read-only; deprecated.

+ * %ETH_TP_MDI_*. If the status is unknown or not applicable, the
+ * value will be %ETH_TP_MDI_INVALID. Read-only.
+ * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of

+ * yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
+ * When written successfully, the link should be renegotiated if

+ * @lp_advertising: Bitmask of %ADVERTISED_* flags for the link modes
+ * and other link features that the link partner advertised
+ * through autonegotiation; 0 if unknown or not applicable.

+ * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
+ * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
+ *
+ * Some hardware interfaces may have multiple PHYs and/or physical

+ * fitted. For these interfaces @port and/or @phy_address may be

+ * Otherwise, attempts to write different values may be ignored or

+ * other than @cmd that are not described as read-only or deprecated,

+ * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of

+ * yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
+ * When written successfully, the link should be renegotiated if
+ * necessary.
+ * @link_mode_masks_nwords: Number of 32-bit words for each of the

+ * %ETHTOOL_GLINKSETTINGS: on entry, number of words passed by user

+ * value returned previously by %ETHTOOL_GLINKSETTINGS, otherwise
+ * refused. For drivers: ignore this field (use kernel's
+ * __ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will
+ * be overwritten by kernel.
+ * @supported: Bitmap with each bit meaning given by
+ * %ethtool_link_mode_bit_indices for the link modes, physical
+ * connectors and other link features for which the interface
+ * supports autonegotiation or auto-detection. Read-only.
+ * @advertising: Bitmap with each bit meaning given by
+ * %ethtool_link_mode_bit_indices for the link modes, physical
+ * connectors and other link features that are advertised through
+ * autonegotiation or enabled for auto-detection.
+ * @lp_advertising: Bitmap with each bit meaning given by
+ * %ethtool_link_mode_bit_indices for the link modes, and other
+ * link features that the link partner advertised through
+ * autonegotiation; 0 if unknown or not applicable. Read-only.
+ * @transceiver: Used to distinguish different possible PHY types,
+ * reported consistently by PHYLIB. Read-only.
+ *
+ * If autonegotiation is disabled, the speed and @duplex represent the
+ * fixed link mode and are writable if the driver supports multiple
+ * link modes. If it is enabled then they are read-only; if the link
+ * is up they represent the negotiated link mode; if the link is down,
+ * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
+ * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
+ *
+ * Some hardware interfaces may have multiple PHYs and/or physical
+ * connectors fitted or do not allow the driver to detect which are
+ * fitted. For these interfaces @port and/or @phy_address may be
+ * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
+ * Otherwise, attempts to write different values may be ignored or
+ * rejected.
+ *
+ * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt
+ * are not available in %ethtool_link_settings. Until all drivers are
+ * converted to ignore them or to the new %ethtool_link_settings API,
+ * for both queries and changes, users should always try
+ * %ETHTOOL_GLINKSETTINGS first, and if it fails with -ENOTSUPP stick
+ * only to %ETHTOOL_GSET and %ETHTOOL_SSET consistently. If it
+ * succeeds, then users should stick to %ETHTOOL_GLINKSETTINGS and
+ * %ETHTOOL_SLINKSETTINGS (which would support drivers implementing

+ *
+ * Users should assume that all fields not marked read-only are

+ * changes and then applying them with %ETHTOOL_SLINKSETTINGS.
+ *
+ * Drivers that implement %get_link_ksettings and/or

* [virtio-dev] [PATCH v2 1/3] scripts/update-linux-headers: add ethtool.h and update to 4.16.0-rc4

From: Jason Baron @ 2018-03-08 3:25 UTC (permalink / raw)
To: qemu-devel; +Cc: mst, jasowang, virtio-dev
A subsequent patch to add support for setting linkspeed/duplex in
virtio-net, requires a few definitions from ethtool.h, which ends up
pulling in kernel.h and sysinfo.h as well.

+ * struct ethtool_cmd - DEPRECATED, link control and status
+ * This structure is DEPRECATED, please use struct ethtool_link_settings.
+ * @cmd: Command number = %ETHTOOL_GSET or %ETHTOOL_SSET
+ * @supported: Bitmask of %SUPPORTED_* flags for the link modes,
+ * physical connectors and other link features for which the
+ * interface supports autonegotiation or auto-detection.
+ * Read-only.
+ * @advertising: Bitmask of %ADVERTISED_* flags for the link modes,
+ * physical connectors and other link features that are
+ * advertised through autonegotiation or enabled for
+ * auto-detection.
+ * @speed: Low bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
+ * @duplex: Duplex mode; one of %DUPLEX_*
+ * @port: Physical connector type; one of %PORT_*
+ * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
+ * applicable. For clause 45 PHYs this is the PRTAD.
+ * @transceiver: Historically used to distinguish different possible
+ * PHY types, but not in a consistent way. Deprecated.
+ * @autoneg: Enable/disable autonegotiation and auto-detection;
+ * either %AUTONEG_DISABLE or %AUTONEG_ENABLE
+ * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO
+ * protocols supported by the interface; 0 if unknown.
+ * Read-only.
+ * @maxtxpkt: Historically used to report TX IRQ coalescing; now
+ * obsoleted by &struct ethtool_coalesce. Read-only; deprecated.
+ * @maxrxpkt: Historically used to report RX IRQ coalescing; now
+ * obsoleted by &struct ethtool_coalesce. Read-only; deprecated.
+ * @speed_hi: High bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
+ * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
+ * %ETH_TP_MDI_*. If the status is unknown or not applicable, the
+ * value will be %ETH_TP_MDI_INVALID. Read-only.
+ * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
+ * %ETH_TP_MDI_*. If MDI(-X) control is not implemented, reads
+ * yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
+ * When written successfully, the link should be renegotiated if
+ * necessary.
+ * @lp_advertising: Bitmask of %ADVERTISED_* flags for the link modes
+ * and other link features that the link partner advertised
+ * through autonegotiation; 0 if unknown or not applicable.
+ * Read-only.
+ *
+ * The link speed in Mbps is split between @speed and @speed_hi. Use
+ * the ethtool_cmd_speed() and ethtool_cmd_speed_set() functions to
+ * access it.
+ *
+ * If autonegotiation is disabled, the speed and @duplex represent the
+ * fixed link mode and are writable if the driver supports multiple
+ * link modes. If it is enabled then they are read-only; if the link
+ * is up they represent the negotiated link mode; if the link is down,
+ * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
+ * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
+ *
+ * Some hardware interfaces may have multiple PHYs and/or physical
+ * connectors fitted or do not allow the driver to detect which are
+ * fitted. For these interfaces @port and/or @phy_address may be
+ * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
+ * Otherwise, attempts to write different values may be ignored or
+ * rejected.
+ *
+ * Users should assume that all fields not marked read-only are
+ * writable and subject to validation by the driver. They should use
+ * %ETHTOOL_GSET to get the current values before making specific
+ * changes and then applying them with %ETHTOOL_SSET.
+ *
+ * Drivers that implement set_settings() should validate all fields
+ * other than @cmd that are not described as read-only or deprecated,
+ * and must ignore all fields described as read-only.
+ *
+ * Deprecated fields should be ignored by both users and drivers.

+ * IMPORTANT, Backward compatibility notice: When implementing new

+ * if it succeeds use %ETHTOOL_SLINKSETTINGS to change link
+ * settings; do not use %ETHTOOL_SSET if %ETHTOOL_GLINKSETTINGS
+ * succeeded: stick to %ETHTOOL_GLINKSETTINGS/%SLINKSETTINGS in
+ * that case. Conversely, if %ETHTOOL_GLINKSETTINGS fails, use
+ * %ETHTOOL_GSET to query and %ETHTOOL_SSET to change link
+ * settings; do not use %ETHTOOL_SLINKSETTINGS if
+ * %ETHTOOL_GLINKSETTINGS failed: stick to
+ * %ETHTOOL_GSET/%ETHTOOL_SSET in that case.
+ *
+ * @cmd: Command number = %ETHTOOL_GLINKSETTINGS or %ETHTOOL_SLINKSETTINGS
+ * @speed: Link speed (Mbps)
+ * @duplex: Duplex mode; one of %DUPLEX_*
+ * @port: Physical connector type; one of %PORT_*
+ * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
+ * applicable. For clause 45 PHYs this is the PRTAD.
+ * @autoneg: Enable/disable autonegotiation and auto-detection;
+ * either %AUTONEG_DISABLE or %AUTONEG_ENABLE
+ * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO
+ * protocols supported by the interface; 0 if unknown.
+ * Read-only.
+ * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
+ * %ETH_TP_MDI_*. If the status is unknown or not applicable, the
+ * value will be %ETH_TP_MDI_INVALID. Read-only.
+ * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
+ * %ETH_TP_MDI_*. If MDI(-X) control is not implemented, reads
+ * yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
+ * When written successfully, the link should be renegotiated if
+ * necessary.
+ * @link_mode_masks_nwords: Number of 32-bit words for each of the
+ * supported, advertising, lp_advertising link mode bitmaps. For
+ * %ETHTOOL_GLINKSETTINGS: on entry, number of words passed by user
+ * (>= 0); on return, if handshake in progress, negative if
+ * request size unsupported by kernel: absolute value indicates
+ * kernel expected size and all the other fields but cmd
+ * are 0; otherwise (handshake completed), strictly positive
+ * to indicate size used by kernel and cmd field stays
+ * %ETHTOOL_GLINKSETTINGS, all other fields populated by driver. For
+ * %ETHTOOL_SLINKSETTINGS: must be valid on entry, ie. a positive
+ * value returned previously by %ETHTOOL_GLINKSETTINGS, otherwise
+ * refused. For drivers: ignore this field (use kernel's
+ * __ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will
+ * be overwritten by kernel.
+ * @supported: Bitmap with each bit meaning given by
+ * %ethtool_link_mode_bit_indices for the link modes, physical
+ * connectors and other link features for which the interface
+ * supports autonegotiation or auto-detection. Read-only.
+ * @advertising: Bitmap with each bit meaning given by
+ * %ethtool_link_mode_bit_indices for the link modes, physical
+ * connectors and other link features that are advertised through
+ * autonegotiation or enabled for auto-detection.
+ * @lp_advertising: Bitmap with each bit meaning given by
+ * %ethtool_link_mode_bit_indices for the link modes, and other
+ * link features that the link partner advertised through
+ * autonegotiation; 0 if unknown or not applicable. Read-only.
+ * @transceiver: Used to distinguish different possible PHY types,
+ * reported consistently by PHYLIB. Read-only.
+ *
+ * If autonegotiation is disabled, the speed and @duplex represent the
+ * fixed link mode and are writable if the driver supports multiple
+ * link modes. If it is enabled then they are read-only; if the link
+ * is up they represent the negotiated link mode; if the link is down,
+ * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
+ * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
+ *
+ * Some hardware interfaces may have multiple PHYs and/or physical
+ * connectors fitted or do not allow the driver to detect which are
+ * fitted. For these interfaces @port and/or @phy_address may be
+ * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
+ * Otherwise, attempts to write different values may be ignored or
+ * rejected.
+ *
+ * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt
+ * are not available in %ethtool_link_settings. Until all drivers are
+ * converted to ignore them or to the new %ethtool_link_settings API,
+ * for both queries and changes, users should always try
+ * %ETHTOOL_GLINKSETTINGS first, and if it fails with -ENOTSUPP stick
+ * only to %ETHTOOL_GSET and %ETHTOOL_SSET consistently. If it
+ * succeeds, then users should stick to %ETHTOOL_GLINKSETTINGS and
+ * %ETHTOOL_SLINKSETTINGS (which would support drivers implementing
+ * either %ethtool_cmd or %ethtool_link_settings).
+ *
+ * Users should assume that all fields not marked read-only are
+ * writable and subject to validation by the driver. They should use
+ * %ETHTOOL_GLINKSETTINGS to get the current values before making specific
+ * changes and then applying them with %ETHTOOL_SLINKSETTINGS.
+ *
+ * Drivers that implement %get_link_ksettings and/or
+ * %set_link_ksettings should ignore the @cmd
+ * and @link_mode_masks_nwords fields (any change to them overwritten
+ * by kernel), and rely only on kernel's internal
+ * %__ETHTOOL_LINK_MODE_MASK_NBITS and
+ * %ethtool_link_mode_mask_t. Drivers that implement
+ * %set_link_ksettings() should validate all fields other than @cmd
+ * and @link_mode_masks_nwords that are not described as read-only or
+ * deprecated, and must ignore all fields described as read-only.

In prepartion for using some of the high order feature bits, make sure that
virtio-net uses 64-bit values everywhere.

* [Qemu-devel] [PATCH v2 3/3] virtio-net: add linkspeed and duplex settings to virtio-net

Although linkspeed and duplex can be set in a linux guest via 'ethtool -s',
this requires custom ethtool commands for virtio-net by default.
Introduce a new feature flag, VIRTIO_NET_F_SPEED_DUPLEX, which allows
the hypervisor to export a linkspeed and duplex setting. The user can
subsequently overwrite it later if desired via: 'ethtool -s'.
Linkspeed and duplex settings can be set as:
'-device virtio-net,speed=10000,duplex=full'
where speed is [0...INT_MAX], and duplex is ["half"|"full"].
