We are trying to build an application over DPDK. However, we are facing 
some issues:

After binding NIC to DPDK driver (igb_uio), we can not see it in 
ifconfig -a.
So, how to bring up that interface and allocate IP to it? We want the 
interface to be up even after our application is terminated. (Using KNI 
module which is provided with DPDK, we were able to give ip address 
which lasts till KNI program is running, but while KNI application is 
running, we can not run any other application (which uses DPDK)).
