Damn, even worse then.
4.14 can work but it requires some backporting in order to support
3B+, I started it some time
ago but newer quite finished.
Got only to 16 patches, but there could potentially be more as a lot
of features are only available in newer kernels.

Currently we are pretty much patching 4.9 kernel to become rpi-4.9.y
branch which is hard to maintain and even harder
to rebase against newer kernels which I assume is why its still stuck on 4.9
