In linux kernel since version 5.1 (release Date: 2019-05-05)  
This driver provides support for virtio based paravirtual
device driver over vDPA bus. For this to be useful, you need
an appropriate vDPA device implementation that operates on a
physical device to allow the datapath of virtio to be
offloaded to hardware.

If unsure, say M.
