okay so welcome to the rte_gtp_hdr(3) page from the Library Functions Manual, bestie. This is the page for rte_gtp_hdr, and it’s giving compact-header energy. 💅✨

🌸 NAME 🌸

rte_gtp_hdr — the simplified GTP protocol header, bestie. No cap, this is the whole name vibe. 🎀

#include <rte_gtp.h>

🎀 Data Fields 🎀

  • uint8_t msg_type
  • rte_be16_t plen
  • rte_be32_t teid

💖 Detailed Description 💖

Okay so here’s the tea: this is a simplified GTP protocol header. It contains an 8-bit header info, an 8-bit message type, a 16-bit payload length after mandatory header, and a 32-bit TEID. It has no optional fields and next extension header — that’s the whole vibe, periodt. 👑
