gtp5g - 5G compatible GTP kernel module
gtp5g is a customized Linux kernel module gtp5g to handle packet by PFCP IEs such as PDR and FAR. For detailed information, please reference to 3GPP specification TS 29.281 and TS 29.244.
Notice
Due to the evolution of Linux kernel, this module would not work with every kernel version.
Please run this module with kernel version 5.0.0-23-generic or upper than 5.4 (Ubuntu 20.04).
Please check the libgtp5gnl version is the same as gtp5g, because the type translating between libgtp5gnl and gtp5g had been changed.
