ENUM BATADV_IV_FLAGS(9)

💅 enum batadv_iv_flags(9) — the Kernel API Manual, but make it make sense

okay so bestie, welcome to the Kernel API Manual entry for enum batadv_iv_flags — the tiny little flag squad that lives inside B.A.T.M.A.N. IV OGM packets. yes, that's a real thing, and yes, it's iconic. let's get into it ✨

---

🌸 NAME 🌸

enum batadv_iv_flags — the flags used in B.A.T.M.A.N. IV OGM packets 🦋

like, that's literally the whole job description and she ate.

---

✨ SYNOPSIS ✨

here's the whole enum, exactly as she is, no edits, no notes:

enum batadv_iv_flags {
    BATADV_NOT_BEST_NEXT_HOP ,
    BATADV_PRIMARIES_FIRST_HOP ,
    BATADV_DIRECTLINK

};

three constants, all up in there, and one of them is honestly just vibing (more on that in a sec 🙈).

---

🎀 Constants 🎀

okay so these are the actual members, and ngl they're each a whole personality:

• BATADV_NOT_BEST_NEXT_HOP — this flag gets set when the ogm packet is forwarded and it was previously received from someone who is not the best neighbor. so like, it's the "we didn't get this from our fave" flag 💀. main character energy denied, respectfully.
• BATADV_PRIMARIES_FIRST_HOP — flag unused. that's it. that's the lore. she's reserved, she's sitting this one out, she's lowkey just holding a seat 🫶 no cap, that's literally all the manual says.
• BATADV_DIRECTLINK — this one's for the first hop 🔥 — or for when the packet is rebroadcasted from a one hop neighbor, but only on the interface where it was originally received. iykyk, the interface matters fr fr, don't come at it from anywhere else.

okay bestie, this is the part where the manpage just lists her entire friend group, and honestly? the roster is long. every single one, in order, no skips:

reminder bestie: these are kernel internals, so treat the details like they're sacred — no inventing flags, no renaming stuff, we keep it exactly as documented 💅

and that's the page!! 🌈 this one came from the source path ./include/uapi/linux, dated October 2026 — so go forth, cite it responsibly, and slay the packet headers, periodt 🍓🎀

bye bestie, ily, read your kernel headers 💖
