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
