A per-virtqueue stopped state is not enough to stop a device because
some devices have global behavior like config change events. It must be
possible to completely stop the device to prevent further activity

Maybe a Device Status register bit can be added for that?

I've considered such case, one of the idea is to introduce a new device
status to achieve which seems more generic. Then we need to define a
state machine carefully.

So I post another RFC to introduce a new device status bit. Please review.
Thanks, that sounds good. I will be offline until January 4th and will
try to catch up then.
