Hi All,
I have a use-case where my slow path application (control path) is to run
on Linux where as my data path is to run as DPDK application. Because both
control and data packets are going to be received via same NIC card, how
will these two flows be separated and passed on to Linux control app
Your application (which you build on top of DPDK) needs to filter which
traffic is control traffic and inject
it into the network stack.
You can leverage DPDK KNI for that (
http://dpdk.org/doc/guides/prog_guide/kernel_nic_interface.html)
Keep in mind you also need to take care of the TX side.

Hi Helin,
If we use exception_path or KNI, which extracts packet from Linux kernel (for
DPDK application processing), will it still remain fast path? Will
