I don't mind lack of new features, but I'd prefer that when we
adopt an external network stack, we adopt one that still sees
maintenance and bug fixes. The repository linked by Antony while
having more recent commits, also has a link to security considerations:

which lists 4 year old security issues that are acknowledged, but

Yes, it can go both ways. I am not arguing in favor of comparing
absolute commit count, but I think we might be better off using
a network stack that we don't have to completely maintain ourselves,
given that we already had a network stack that we maintained ourselves
that we are looking to substitute.

In the end, the one who does the work is probably who gets to choose
(and argue their choice).

Thanks for your input. My only interaction with lwIP so far was some
weekend time spent on integrating it into the barebox build system,
but I haven't went further than that to actually wire it with the network API.

I think best case, we would proceed as suggested by Antony: Rework
the interfaces in barebox, so both the existing network stack and lwIP
(or picotcp) can be integrated using the same APIs.

Did you try integrating picotcp instead? What issues did you run into?
