This sample driver creates mdev device that simulate virtio net device

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.
Can we please submit a real driver for it? A more or less useless
sample driver doesn't really qualify for our normal kernel requirements
that infrastructure should have a real user.
Intel posted a real driver here: https://lkml.org/lkml/2019/10/15/1226.
I plan to post another driver that wire virito-pci back to mdev bus on
top of this series as well.
Thanks
