I think something like this might fix the problem.

You may also drop 'default n' :-)
But what I want to say is that API is under NET_UTILS, I dunno if the
driver requires full NET to be selected. And IIRC NET_UTILS is
selected by NET.

I think GENERIC_NET_UTILS might be enough.
The problem I have for the moment is to find or1k-linux-gcc for my Fedora 33...

Good!

Usually for a compilation test for the kernel is enough to have
precompiled compilers from kernel.org [1].

NET isn't usually selected, maybe depends on NET
