DESCRIPTION
   vdpa dev show - display vdpa device attributes
       DEV - specifies the vdpa device to show.  If this argument is omitted
       all devices are listed.
           Format is:
             VDPA_DEVICE_NAME
   vdpa dev add - add a new vdpa device.
       name NAME
              Name of the new vdpa device to add.
       mgmtdev MGMTDEV
              Name of the management device to use for device addition.
       device_features DEVICE_FEATURES Specifies the virtio device features
       bit-mask that is provisioned for the new vdpa device.
       The bits can be found under include/uapi/linux/virtio*h.
       see macros such as VIRTIO_F_ and VIRTIO_XXX(e.g NET)_F_ for specific
       bit values.
       This is optional.
       mac MACADDR - specifies the mac address for the new vdpa device.  This
       is applicable only for the network type of vdpa device. This is
       optional.
       mtu MTU - specifies the mtu for the new vdpa device.  This is applica-
       ble only for the network type of vdpa device. This is optional.
   vdpa dev del - Delete the vdpa device.
       DEV - specifies the vdpa device to delete.
   vdpa dev config show - Show configuration of specific device or all
       devices.
       DEV - specifies the vdpa device to show its configuration.  If this
       argument is omitted all devices configuration is listed.
           Format is:
             VDPA_DEVICE_NAME
   vdpa dev vstats show - shows vendor specific statistics for the given
       device and virtqueue index. The information is presented as name-value
       pairs where name is the name of the field and value is a numeric value
       for it.
       DEV    - specifies the vdpa device to query
       qidx QUEUE_INDEX
              - specifies the virtqueue index to query
