Thanks for your reply !
I used to run KNI in similar manner and I tested KNI sample application.
Came to know the reason behind dpdk0 interface ceration.
I am using mTCP package which contains dpdk integrated it. mTCP team
modified the igb_uio driver code to create dpdk# interfaces when the PCI
address is assigned igb_uio driver. so that's the reason I am seing dpdk0
interface when I run setup.py script and attach a device to igb_uio driver.
The dpdk0 interface will not be created by plain DPDK libraray/driver.
So I think I have to check with mTCP library to remove dependency with
dpdk0 interface to achieve what I need.
