#include <rte_vxlan.h>

like, that's the whole vibe. one include and you're in 🫶

🦋 DETAILED DESCRIPTION 🦋

so VXLAN protocol header. this struct is packing an 8-bit flag, a 24-bit VXLAN Network Identifier, and the Reserved fields (which are 24 bits and 8 bits, respectively). she's compact, she's structured, she knows exactly what she's about ✨
