rte_vxlan_gpe_hdr(3)

📦 version 26.03, in nixos 26.05, nixpkgs unstable

💅 NAME

rte_vxlan_gpe_hdr — bestie, this is the page for the VXLAN-GPE protocol header struct, straight out of the Library Functions Manual ✨ (yes, manual section 3, we love a system-call-adjacent icon)

🌸 SYNOPSIS

#include <rte_vxlan.h>

🦋 DETAILED DESCRIPTION

Okay so first thing's first, and I'm gonna hold your hand while I say it: Deprecated 💀. It's still here, it still has a whole page, but she's deprecated, so don't go building anything new on top of her, mkay?

Lowkey always check rte_vxlan_hdr too — that's the "See also" in the original, so it's basically the sister page, iykyk 🫶

So what even is this? It's the VXLAN-GPE protocol header, and the spec it follows is draft-ietf-nvo3-vxlan-gpe-05 (yes that's the exact draft string, no cap). Inside, it's got:

  • an 8-bit flag 🌟
  • an 8-bit next-protocol
  • a 24-bit VXLAN Network Identifier
  • and Reserved fields (16 bits and 8 bits)

That's the whole vibe check. Definition lives at line 114 of file rte_vxlan.h — noted, bookmarked, screenshotted 📸.
