README

Excerpt

AF_XDP

Purpose

Guide agents through AF_XDP sockets for high-performance packet I/O: socket creation, UMEM setup, fill/completion/RX/TX rings, XDP programs with XDP_REDIRECT to XSK, copy vs zero-copy modes, libbpf helpers, performance comparison with DPDK, and production use cases.

When to Use

Building a userspace packet processor with lower overhead than raw sockets
Redirecting XDP-filtered traffic to userspace without DPDK complexity
Implementing a custom load balancer or IDS dataplane
Comparing zero-copy vs copy mode on your NIC/driver
Integrating with existing libbpf/XDP infrastructure
Need kernel cooperation (firewall rules) plus userspace processing
