[PATCH 0/2] virtio_net: allow hypervisor to indicate linkspeed and duplex setting

[Jason Baron]

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.

The ability to set linkspeed and duplex was introduced by:

16032be virtio_net: add ethtool support for set and get of settings

And using 'ethtool -s' continues to over-write the linkspeed/duplex
settings with this patch.

The 1/2 patch is against net-next, while the 2/2 patch is the associated
qemu changes that would go in after as update-linux-headers.sh should
be run first. So 2/2 is more meant as a demonstration of how I intend this
to work.

Thanks,

-Jason
