✨ NAME ✨

okay so bestie, meet rte_node_ip4_api.h 💖 — a header from DPDK's Library Functions Manual (you know the drill, section 3, iykyk) and it's literally the control-path bestie for the ip4_* graph nodes. no cap.

🌸 Detailed Description 🌸

⚠️ Warning EXPERIMENTAL: All functions in this file may be changed or removed without prior notice. 💀 so like... don't build your entire personality on this API, bestie, it could ghost you at any release.

This API allows to do control path functions of ip4_* nodes like ip4_lookup, ip4_rewrite. 🦋
