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.
