This sample driver creates mdev device that simulate virtio net

driver to work.
Only 'virtio' type is supported right now. I plan to add 'vhost' type
on top which requires some virtual IOMMU implemented in this sample
driver.

I'd prefer it that we call this something else, e.g.
mvnet-loopback. Just so people don't expect a fully
functional device somehow. Can be renamed when applying?
Actually, I plan to extend it as another standard network interface for
kernel. It could be either a standalone pseudo device or a stack
device.
Does this sounds good to you?
Thanks
That's a big change in an interface so it's a good reason
to rename the driver at that point right?
Oherwise users of an old kernel would expect a stacked driver
and get a loopback instead.
Or did I miss something?
My understanding is that it was a sample driver in /doc. It should not
be used in production environment. Otherwise we need to move it to
driver/virtio.
But if you insist, I can post a V11.
Thanks
Or maybe it's better to rename the type of current mdev from 'virtio' to
'virtio-loopback'. Then we can add more types in the future.
Thanks
