Target does not have the DPDK KNI Module & KNI: Can not open /dev/kni #8

I have installed UDPDK on my server machine which has enp5s0f0 and enp5s0f1 NIC card and I followed all the steps as mentioned in the Readme.md file but when I was inserting KNI module while setting up linux environment by using ./dpdk-setup.sh, it is giving me the error "Target does not have the DPDK KNI Module. To fix, please try to rebuild target". I did rebuilt the target but the error remains the same. Also while I was running the sample applications (ip_pipeline) under example folder of DPDK, I am stucking at KNI: Can not open /dev/kni message.

What I have done

1.) I read the DPDK Documentation from [https://doc.dpdk.org/guides/prog_guide/kernel_nic_interface.html](the following page) and in its 47.1 point it states that you need to load rte_kni.ko file which is not available in /kernel/linux/kni of DPDK (version 20.05). 2.) I enabled CONFIG_RTE_LIBRTE_KNI=y which is in UDPDK/deps/dpdk/config# nano common_base.

How to enable/import KNI module into DPDK. And how to get rte_kni.ko file in /kernel/linux/kni.

Hi Ashish, your error relates to DPDK (as opposed to UDPDK) so you may get more help by asking to the DPDK community.
The documentation in your link refers to the latest version, that's why it may be inconsistent with the version you use; I recommend checking the docs for 20.05.

Okay, thanks
