You need to have KNI module enabled in the config.
By default all kernel modules in DPDK are now disabled.

Set
CONFIG_RTE_KNI_KMOD=y

Then after build you will find kni module in the build result.
You will have to manually insmod it.

I assume you are using older release with make (not current releases with meson).
