Why 10G ?
Yuanhan, any opinion?

Just wanted this to be consistent with below (From virtio_dev_link_update):
link.link_speed = SPEED_10G;
Need to put some value in speed_capa.

OK, that's the kind of justification which are good to have in
the commit message.

The chosen fake capability (10G) is consistent with the reported
link speed in virtio_dev_link_update():
link.link_speed = SPEED_10G;
The feature is not marked in doc/guides/nics/features/virtio.ini
as it is only a fake value.
