✨ rte_flow_item_vxlan ✨

okay bestie, so this is rte_flow_item_vxlan(3) from the Library Functions Manual, and it's literally all about one thing: the VXLAN flow item. buckle up 🦋

💖 SYNOPSIS 💖

#include <rte_flow.h>

that's it. that's the include. pull it in and you're in business 💅

🌸 DETAILED DESCRIPTION 🌸

RTE_FLOW_ITEM_TYPE_VXLAN.

So like, what does it actually do? It matches a VXLAN header (that's RFC 7348, no cap, it's iconic), and it also handles GPE — aka draft-ietf-nvo3-vxlan-gpe-13.txt — and GBP — aka draft-smith-vxlan-group-policy-05.txt. two drafts, one item, we love a multitasker 👑

Now, here's the tea on GPE: you tell it apart by its UDP port. and that UDP port? you can specify it with rte_eth_dev_udp_tunnel_port_add(). write that down 📝
