Hi All,
   I am trying to bind virtio interface with my dpdk application.
Binding was successful but LINK create is failed in the log I am seeing
Port which was bound not probed in startup.
Please suggest how to bind the virtio interface into dpdk.

Steps I have tried to bind the port:

  1.  modprobe uio_pci_generic
  2.  dpdk-devbind.py -b uio_pci_generic  0000:02:00.0 0000:03:00.0
  3.  dpdk-devbind.py -s
