QE tested this series's v3 again. Creating two vdpa_sim devices, and
boot two VMs without shadow virtqueues. The migration was successful and
everything worked fine.

Hi Eugenio,
I've tested this patch series on Xilinx/AMD SN1022 device without
control vq and VM Live Migration between two hosts worked fine.

HI Eugenio, thanks for the series!
I tested the series with our DPU, SolidNET.
The test went as follow:
- Create 2 virtio net vdpa devices, every device in a separated VF.
- Start 2 VMs with the vdpa device as a single network device, without
shadow vq.
The source VM with "-netdev
It's possible to migrate vdpa net devices if they are shadowed from the
start. But to always shadow the dataplane is to effectively break its host
passthrough, so its not convenient in vDPA scenarios.
This series enables dynamically switching to shadow mode only at
migration time. This allows
