Jesper Dangaard Brouer f400662c53 Merge pull request #60 from freysteinn/traffic-pacing-edt-fix

traffic-pacing-edt: Fixed an operator precedence issue in codel_impl.h

This bug caused to CoDel control law to always stay at the initial 100 ms drop interval.
After this fix the control law behaves correctly, by becoming more aggressive (smaller next drop intervals)
in accordance with the inverse square root (that TCP traffic responds to).

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).
