STRUCT FLOW_DISSECTOR_KEY_ARP(9)

💅 struct flow_dissector_key_arp(9) ✨

okay so bestie, we're in the Kernel API Manual today and this page is about struct flow_dissector_key_arp — yes the whole entire title, no nickname, she goes by her full government name 😭

---

🎀 NAME 🎀

struct flow_dissector_key_arp — and that's it. That's the whole description. The original literally leaves it blank after the dash, and honestly? main character energy. she said "my name is enough" 💅✨

---

🌸 SYNOPSIS 🌸

here's the struct in all her glory, copy it exactly bestie, don't you dare retype it by hand:

struct flow_dissector_key_arp {
    __u32 sip;
    __u32 tip;
    __u8 op;
    unsigned char sha[ETH_ALEN];
    unsigned char tha[ETH_ALEN];
 };

look at her. five fields. zero notes. perfection 🫶

💖 Members 💖

okay so every field gets a little moment:

• sip — Sender IP address 🦋 the address of whoever's sending, bestie
• tip — Target IP address 🎯 who it's headed to, no cap
• op — Operation 🌈 the op, the vibe check of what's actually happening
• sha — Sender hardware address 💌 the sender's hardware address, ETH_ALEN bytes of it
• tha — Target hardware address 📬 and the target's hardware address, also ETH_ALEN bytes

that's the whole struct. nothing hidden, nothing spicy, just ARP facts delivered with love 🧚

okay that's the page!! before you go — this whole thing is filed under ./include/net, it's stamped October 2026, and the footer literally just repeats struct flow...ctor_key_arp(9) at us one more time for good measure 💜 slay, bye bestie, go dissect some flows 🌸✨🦋
