it would be great to have some CI setup where both current stable as
well as a development branch of the code is tested, and reports
published regularly.  Not sure how realistic that is.

Well, then those tools need to be adapted accordingly.  That's what I
also indicated in other mails:  Changes in the kernel GTP code should
always be followed-up with correspondign changes in libgtpnl and
associated tools.  I mean, the tool could just open the socket and then
continue to run until terminated explicitly...

I think there's a lot of value in some very low-level tools for testing
and experimentation, without the complexity of configuring + running an
Erlang GGSN/P-GW with all its dependencies.
