Hi,

Even if nobody is actually going to implement an SR-IOV enabled device
on top of this really soon, having it in QEMU should be handy.

I know at least a hardware vendor that used those bits to emulate their SR-IOV device.
Sadly their code will not come to QEMU, at least not so soon. (I'll ask at least for a "tested-by" tag)

Maybe somebody will want to enable SR-IOV for virtio :)

This is why I proposed to have a "how-to" doc for the first implementation.
The implementer will choose then how to deal with this doc.

I'll go over the code again and add my "Reviewed-by".

Thanks!
Marcel
