Hi Bruce,
Thanks for your reply.
I used dpdk_nic_bind.py script to bind igb_uio driver for the specific NIC ports.
[root at SSBC swe]# ./ dpdk_nic_bind.py --status
Network devices using IGB_UIO driver
====================================
0000:03:00.0 'VMXNET3 Ethernet Controller' drv=igb_uio unused=vmxnet3
0000:13:00.0 'VMXNET3 Ethernet Controller' drv=igb_uio unused=vmxnet3
0000:1b:00.0 'VMXNET3 Ethernet Controller' drv=igb_uio unused=vmxnet3
Network devices using kernel driver
===================================
0000:0b:00.0 'VMXNET3 Ethernet Controller' if=ha0 drv=vmxnet3 unused=igb_uio
When we ported to DPDK1.7.0, we didn't face this kind of issues.
When I googled, found similar problem. But didn't get any solution from that.

Please give some directions to resolve this issue.

Varun

After you load the uio driver, you still need to bind some NIC devices to use it, otherwise DPDK will ignore those devices as being used by the kernel.
The script "dpdk_nic_bind.py" in the tools directory can help with the binding and unbinding to the different drivers.
