I think what they're saying is the Altera port of lwIP is old and they
don't support it anymore.  lwIP itself has had a lot of development
since they ported it to their hardware, and continues to do so.

Not really.  There is some code, but it's incomplete and probably
doesn't work.  None of the current active developers have an interest in
IPv6 (yet) and so it's not received much attention.  I'd be happy if
someone wanted to change this.

That depends what you want to use it for.  lwIP is very much aimed at
low memory systems, so won't be the right choice for all projects, but
it has more bells and whistles than you might first expect.  The best
thing to do is come up with a list of requirements and see if lwIP meets
those, as such an open-ended question is hard to answer.

Hope that helps,
