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.

Do we need to change other vdpa parent like the simulator and ifcvf? Thanks
