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
Network devices using DPDK-compatible driver
