virtio_net: Introduce VIRTIO_NET_F_STANDBY feature bit

2018-05-29T02:59:54Z

This feature bit can be used by hypervisor to indicate virtio_net device to act as a standby for another device with the same MAC address. VIRTIO_NET_F_STANDBY is defined as bit 62 as it is a device feature bit. Signed-off-by: Sridhar Samudrala Signed-off-by: David S. Miller

virtio_net: propagate linkspeed/duplex settings from the hypervisor

2018-01-09T16:37:56Z

The ability to set speed and duplex for virtio_net is useful in various scenarios as described here: 16032be virtio_net: add ethtool support for set and get of settings However, it would be nice to be able to set this from the hypervisor, such that virtio_net doesn't require custom guest ethtool commands. 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'. Note that VIRTIO_NET_F_SPEED_DUPLEX is defined as bit 63, the intention is that device feature bits are to grow down from bit 63, since the transports are starting from bit 24 and growing up.

virtio_net: add _UAPI prefix to virtio_net header guards

2016-06-11T06:03:55Z

This gives better namespacing and prevents conflicts with no-uapi version of virtio_net header that will be introduced in the following patch. Signed-off-by: Mike Rapoport Signed-off-by: David S. Miller

virtio_net: Update the feature bit to comply with spec

2016-06-10T06:35:26Z

A draft version of the MTU Advice feature bit was specified as 25. This bit is not within the allowed range for network device feature bits, and should be changed to be feature bit 3 to fully comply with the spec.

virtio-net: Add initial MTU advice feature

2016-06-07T01:08:49Z

This commit adds the feature bit and associated mtu device entry for the virtio network device. When a virtio device comes up, it checks the feature bit for the VIRTIO_NET_F_MTU feature. If such feature bit is enabled, the driver will read the advised MTU and use it as the initial value. Signed-off-by: Aaron Conole Signed-off-by: David S. Miller

virtio_net: document VIRTIO_NET_CTRL_GUEST_OFFLOADS

2015-07-01T08:11:17Z

Document VIRTIO_NET_CTRL_GUEST_OFFLOADS and the relevant feature bits. Will allow ethtool control of the offloads down the road. Reported-by: Yan Vugenfirer Signed-off-by: Michael S. Tsirkin

virtio_net: unconditionally define struct virtio_net_hdr_v1.

2015-02-17T05:49:27Z

This was introduced in commit ed9ecb0415b97b5f9f91f146e1977bb372c74c6d, but only defined if !VIRTIO_NET_NO_LEGACY. We should always define it: easier for users to have conditional legacy code. Suggested-by: "Michael S. Tsirkin" Signed-off-by: Rusty Russell

virtio: Don't expose legacy net features when VIRTIO_NET_NO_LEGACY defined.

2015-02-13T06:45:54Z

In particular, the virtio header always has the u16 num_buffers field. We define a new 'struct virtio_net_hdr_v1' for this (rather than simply calling it 'struct virtio_net_hdr', to avoid nasty type errors if some parts of a project define VIRTIO_NET_NO_LEGACY and some don't. Transitional devices (which can't define VIRTIO_NET_NO_LEGACY) will have to keep using struct virtio_net_hdr_mrg_rxbuf, which has the same byte layout as struct virtio_net_hdr_v1.

virtio_net: v1.0 endianness

2014-12-09T10:05:26Z

Based on patches by Rusty Russell, Cornelia Huck. Note: more code changes are needed for 1.0 support (due to different header size). So we don't advertize support for 1.0 yet. Signed-off-by: Rusty Russell Signed-off-by: Cornelia Huck Signed-off-by: Michael S. Tsirkin
