There is no "roadmap" from my point of view, as I (and the sysmocom
team) currently have no customer requirements/requests/projects on this.
As sysmocom is not a group of volunteers doing things in their spare
time but a team of paid engineers, we can primarily work only on those
topics where there are customer requirements.

For Pablo (another co-author of the module) it is the same.

I'm very happy to do project based work around the kernel GTP module,
in whatever direction, just as long as it is about generally useful
features while within relevant specifications and architecturally fits
the code and the Linux kernel stack.

For Andreas and his employer Travelping the situation is quite
different.  As far as I understand they do have customer
projects/requirements  that drive the development.  But I can of course
not speak for him, and he can comment on this himself.

If you can work on it, by all means do so.  I think particularly the
IPv6 support (both on the user payload (inner IP) as well as the outer
transport IP is much appreciated by everyone.

It may make sense to coordinate with Andreas, to make sure there's not
too many merge conflicts between his work and yours.
