[PATCH] vdpa/mlx5: Setup driver only if VIRTIO_CONFIG_S_DRIVER_OK
...#39;re relying upon?
Ok, I think the map is still there, we just avoid to create some
resources.
> With current qemu 5.1 with lack of batching support, I get plenty calls
> to set_map which result in calls to mlx5_vdpa_change_map().
> If that happens before VIRTIO_CONFIG_S_DRIVER_OK then Imay fail (in case
> I was not called to set VQs ready).
Right, this could be solved by adding the batched IOTLB updating.
Thanks
