Sorry Rajesh, but there is no support available on DPDK for the C2xxx QuickAssist device.
DPDK PMDs start from the DH895xCC device. 
If you contact your Intel field rep or get in touch with me directly with details of your use case we can help you to find a QuickAssist device which satisfies your acceleration requirements and is supported on DPDK.
