Introduction
------------
This series is based on the RFC series submitted by Yui Washizu[1].
See also [2] for the context.
This series enables SR-IOV emulation for virtio-net. It is useful
to test SR-IOV support on the guest, or to expose several vDPA
devices in a
VM. vDPA devices can also provide L2 switching feature for offloading
though it is out of scope to allow the guest to configure such a
feature.
The new code of SR-IOV emulation for virtio-net actually resides in
virtio-pci since it's specific to PCI. Although it is written in a way
agnostic to the virtio device type, it is restricted for virtio-net
because
of lack of validation.
