The kci_test_encap_fou() test from kci_test_encap() in rtnetlink.sh needs the fou module to work. Otherwise it will fail with:

$ ip netns exec "$testns" ip fou add port 7777 ipproto 47 RTNETLINK answers: No such file or directory Error talking to the kernel

Add the CONFIG_NET_FOU into the config file as well. Which needs at least to be set as a loadable module.
