Toke Høiland-Jørgensen ff3e4272ff Integrate libxdp as a submodule

This adds libxdp as a submodule and link target alongside libbpf. This
should make it just as easy for examples to use libxdp as it currently is
for libbpf. Some hoops need to be jumped through to make libxdp link
against the same version of libbpf as the one we use in this repository.

Practical BPF examples

This git repository contains a diverse set of practical BPF examples that solve (or demonstrate) a specific use-case using BPF.

It is meant to ease doing rapid prototyping and development, writing C-code BPF programs using libbpf. The goal is to make it easier for developers to get started coding.

Many developers struggle to get a working BPF build environment. The repo enviroment makes it easy to build/compile BPF programs by doing the necessary libbpf setup transparently and detect missing compile dependencies (via the configure script). It is a declared goal to make BPF programming more consumable by detecting and reporting issues (when possible).
