how to work with free5gc

[cleverchou]

If free5gc' NF as control plane, how to configure this UPF-BPF, for example: N3 INTERFACE 、 N6 INTERFACE、 N4 INTERFACE

@cleverchou Unfortunately, today the upf-bpf can not integrate with free5gc. Upf-bpf is a C++ library. There is a discussion #52 regarding the integration with OAI (just because it is implemented using C++). You could to take a look to understand how it could be done. If you have other question. Please, do not hesitate to ask.

@cleverchou, I am not expert in golang, but maybe one option is to use cgo inside the free5g/upf component. So, we could import this library to this component to enable the XDP path.
