thanks for reaching out about this.

I've quickly looked at the documents you linked, and they don't really
state anything beyond "use IPsec for GTP".  Specifically, the do not
specify how to do key distribution, how to set up the SAs, whether they
use a standard IKEv2 or something else, ...

As Linux has a fairly complete IPsec implementation consisting of the
kernel-level IPsec transforms with its netlink interface and e.g. the
Strongswan userland, I don't really think there is anything that would
need to be done in addition to configuring both this IPsec stack and
OpenGGSN.

So what exactly would you want to do?  Am I missing something?
