In order to control the kernel-side GTP-U plane (gtp driver), a
netlink based control interface between GTP-C in userspace and GTP-U in
kernelspace was invented.
The encoding and decoding of these control messages is implemented in this libgtpnl (library for GTP netlink).
libgtpnl is part of the Osmocom Open Source Mobile Communications project.
The official homepage of the project is https://osmocom.org/projects/linux-kernel-gtp-u/wiki/Libgtpnl
You can clone from the official libgtpnl.git repository using
git clone https://gitea.osmocom.org/cellular-infrastructure/libgtpnl
