[dpdk-dev] KNI sample application running procedure

["Abdul, Jaffar" <jabdul@ciena.com>]

Hi Guys,

I am trying to run the KNI sample application according to the DPDK documentation which is given below.

http://dpdk.org/doc/guides/sample_app_ug/kernel_nic_interface.html#running-the-application

I am not able to run the app successfully, 

I don't have this problem with any other DPDK example application and I also verified that I have loaded the *.ko files properly (rte_kni.ko, igb_uio.ko, etc.)

I have also loaded rte_kni.ko with kthread_mode single/multiple but both results are same.

I am using two 1G ports in this example which are port 0 and port 1 and it has been attached to DPDK through (dpdk_nic_bind.py) script.

Output of the dpdk_nic_bind.py

we are using dpdk v2.1 at this moment, any suggestions to make this work would be a great help for me.

Please let me know if you need more info on this

Thanks a lot in advance! 

Thanks
