Welcom to the (cellular) telecom world. Feels like the state of Linux in the
mid-1990ies: Some minimal FOSS implementations exist, but most of the work still
has to be done. We've been trying hard since 2008 inside Osmocom, but as indicated
so far no 4G related contributions (financially or in terms of code).

Are we talking about FOSS development here?

What exactly do you want to prototype? Which of the many GTPv2-C
transactions do you need? I guess if you can deal e.g. without
relocation, then the complexity is quite reduced.

correct. We've just added user-plane IPv6 support to openggsn in
userspace, v6 user plane (or even transport plane) in kernel GTP is
still another area looking for contributions.
