We do not create Netdev from vdpa parentdev.
From vdpa parentdev, only vdpa device(s) are created which is 'struct device' residing in /sys/bus/vdpa/<device>.
Currently such vdpa device is already created on mlx5_vpa.ko driver load, however user has no way to inspect, stats, get/set features of this device, hence the vdpa tool.
