STRUCT FLOW_DISSECTOR_KEY_IPV4_ADDRS(9)

💖 struct flow_dissector_key_ipv4_addrs(9) 💖

okay so welcome to the Kernel API Manual, bestie — section 9, the deep lore section, we're literally in the headers rn 🧚

---

✨ NAME ✨

struct flow_dissector_key_ipv4_addrs —

and ngl the manpage just… ends the sentence there 😭 no description, no little blurb, nothing. It's giving mysterious main character energy. The name speaks for itself and honestly? It ate. 🫶

---

🌸 SYNOPSIS 🌸

struct flow_dissector_key_ipv4_addrs {
    __be32 src;
    __be32 dst;
};

that's the whole vibe. two fields, both __be32, both iconic 💅

---

🦋 Members 🦋

• src — the source ip address 🎀
• dst — the destination ip address ✨

like, who's calling and who's getting called. that's it. that's the struct. lowkey obsessed with how simple this is.

fr fr though — these are __be32, so big-endian, no cap. Don't go flipping bytes on me 🙈

okay so that's the whole page! short and sweet, just how we like it. this one lives in ./include/net and the version stamp says October 2026 — so yeah, she's from the future, we stan a time traveler 🕰️✨

go forth and dissect those IPv4 addrs, bestie — you got this 💖🎀💅
