We have found it useful to be able to set the linkspeed and duplex
settings from the host-side for virtio_net. This obviates the need
for guest changes and settings for these fields, and does not require
custom ethtool commands for virtio_net.

In prepartion for using some of the high order feature bits, make sure that

The ability to set speed and duplex for virtio_net is useful in various
scenarios as described here:

However, it would be nice to be able to set this from the hypervisor,
such that virtio_net doesn't require custom guest ethtool
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
