Looks like this is not enough:

# 1..2
# open tun device: No such file or directory
# not ok 1 ipv4
# open tun device: No such file or directory

Resulting config in the build:

# CONFIG_TUN is not set

Keep in mind the "Important" note here:

I recommend using a fresh tree or mrproper for testing vng configs.

Feel free to post v2 without the 24h wait, it's a bit tricky to handle
new targets in CI, sooner we merge this the less manual work for me..
