Add a small utility that uses a kprobe to extract the currently active slave ifindex from a bond interface. This value is normally only exported to userspace for bond types where it can be explicitly set, but the bond driver has an internal notion of an active interface regardless of the bond type. We can extract this value with a kprobe by attaching to a function in the bond driver and triggering an operation that causes this function to be called.

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).
