Hi,
I have three ethernet interfaces in my VirtualBox as shown below:
root at VirtualBox:/home/akabra/dpdk/dpdk-2.0.0/tools# ifconfig

0000:00:08.0 '82540EM Gigabit Ethernet Controller' if=eth2 drv=e1000

I will now add eth2 to DPDK
root at manav-VirtualBox:/home/globus/dpdk/dpdk-2.0.0/tools# sudo ifconfig
eth2 down
root at manav-VirtualBox:/home/globus/dpdk/dpdk-2.0.0/tools#
./dpdk_nic_bind.py -b igb_uio 0000:00:08.0
I now see that eth2 has been removed from my ifconfig output. I cant seem
to understand why this has happened?

I see that it has been successfully recognized as an interface using DPDK
driver, but why dont i see it in my ifconfig. Any ideas here?

Would appreciate some help here.
