To fully utilize DPDK's performance, it is recommended to use native
userspace drivers.
Because userspace drivers do not interact with your kernel,
it is trivial not having 'interfaces' for your kernel.
YES you are bypassing whole kernel, if you are using userspace drivers.
You may need KNI when:
DPDK's igb_uio driver does not generate 'netdev' interfaces,
so you cannot see any interface via ifconfig.
(However, they are registered as 'rte_eth_dev' in your DPDK application.)
You'd better to use KNI drivers to have 'netdev' intefaces.

Hi Keunhong,
Thanks for the response.
I was reading about KNI (
http://dpdk.org/doc/guides/sample_app_ug/kernel_nic_interface.html), and
that seems to defeat the purpose of DPDK -- the whole point of using DPDK
was to bypass the kernel. Now, when i implement KNI, then packets emanating
from the D
Hi,
I have three ethernet interfaces in my VirtualBox as shown below:
