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'
I was thinking whether or not it's better to decide the duplex by the type of backends.
E.g userspace and vhost-kernel implement a in fact half duplex. But dpdk implement a full duplex.

where speed is [0...INT_MAX], and duplex is ["half"|"full"]. Signed-off-by: Jason Baron<jba...@akamai.com> Cc: "Michael S. Tsirkin"<m...@redhat.com> Cc: Jason Wang<jasow...@redhat.com> Cc:virtio-...@lists.oasis-open.org ---
