[PATCH v3 0/3] virtio_net: allow hypervisor to indicate linkspeed and duplex setting
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.
The ability to set linkspeed and duplex is useful in various cases
as described here:
