Does it run 'with' the DPDK in the userspace and is your tcp client applica= tion interacting over sockets to that tcpip stack in user space ? If your stack is running in the kernel, then ofcourse you have to use a tap= interface to interface with the kernel. Can you describe your usecase in more details eg. what is the dpdk app, is = the tcp client itself the dpdk app and so forth. Normally, I use tcpclient/server as a normal linux kernel interfacing apps.= I run a DPDK app and use a tap interface to switch packets in an out of th= e kernel. The kernel interacts over sockets with tcpclient/server as usual.

Now, to check whether the setup works, I started *TCP Server application*on= another machine and connected the LAN cable to the port which is controlle= d by DPDK. And I am running *TCP client application* on the machine having DPDK and ru= mpkernel tcpip stack. The tcp client and server cannot communicate, is there some other configura= tion to be taken care for the traffic to flow appropriately on the machine = running DPDK. I have checked similar posts on the mailing list, but didnot get clue on ho= w to debug the issue I am facing. Any pointer/suggestions would be really of great help. -- Regards Gopi Krishna =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D Please refer to http://www.aricent.com/legal/email_disclaimer.html for important disclosures regarding this electronic communication. =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D
