rte_flow_item_vxlan(3)

💜 rte_flow_item_vxlan — the rte_flow manual page, bestie edition

okay so real talk, this is the page for rte_flow_item_vxlan from the rte_flow family of manual pages (Library Functions Manual). it's a struct doc, it's short, it's iconic, let's go. 🎀

✨ SYNOPSIS ✨

#include <rte_flow.h>

that's it. one include and you're in. 🫶

---

🌸 DETAILED DESCRIPTION 🌸

so RTE_FLOW_ITEM_TYPE_VXLAN is the flow-item type you reach for when you're matching a VXLAN header (that's RFC 7348, no cap 💅) — and yes, it covers GPE too (draft-ietf-nvo3-vxlan-gpe-13.txt) and GBP (draft-smith-vxlan-group-policy-05.txt). we love a multi-draft queen.

GPE is distinguished with its UDP port. (iykyk — the port is the whole personality.) That UDP port may be specified with rte_eth_dev_udp_tunnel_port_add().

uint8_t vni[3]

The VXLAN identifier — the main character of this whole struct honestly 👑
