gtp: add flags to gtp_tunnel object Flags tells us what fields have been set in this object. This is required by ./gtp-tunnel del otherwise, build helper function adds the MS/UE address and kernel reports ENOENT, and tunnel identifier is ignored. Update gtp-tunnel tool to set flowid to zero in the GTP version 0 case, otherwise kernel reports EINVAL since now this flag is not ever set. Change-Id: I66677ab2d4de2c459ed9987c465fce6f059d6d93
In order to control the kernel-side GTP-U plane, 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 the 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
