Configure max supported virtqueues on the management device. This info
can be retrieved using:
$ vdpa dev show
vdpa-a: type network mgmtdev auxiliary/mlx5_core.sf.1 vendor_id 5555 \
max_vqp 3 max_vq_size 256 max_supported_vqs 256
I still think we should report 257 here to be aligned with the spec even if
we know cvq is probably emulated.
OK, you mean report 257 for max_supported_vqs?
Yes.

Do we need to change other vdpa parent like the simulator and ifcvf?
I can change for the simulator but not sure I know how to do it for
ifcvf or other drivers.
Adding LingShan to answer this question.
And we don't need to care about eni and vp_vdpa now since they don't
support mgmt devices yet.
Thanks
