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"].
