[dpdk-dev] igb_uio binding issue

[Pankaj Joshi]

Hello,

I am running DPDK sample application of l2_fwd.
I have some of the ports like ,

Network devices using IGB_UIO driver
====================================
0000:84:00.0 'I350 Gigabit Network Connection' drv=igb_uio unused=
0000:84:00.1 'I350 Gigabit Network Connection' drv=igb_uio unused=

Other network devices

<none>

I have binded two port, but while running application it is searching for
ports which I have not binded.. Logs are showing as below :

Can any one figure out the problem.
