STRUCT BATADV_TVLV_HDR(9)

💅 struct batadv_tvlv_hdr(9) — the Kernel API Manual page, bestie edition 🎀

Okay so you opened the manual for struct batadv_tvlv_hdr(9), and honestly? It’s a tiny little icon. This is the base tvlv header struct, and it’s giving “small but runs the group chat” energy. Let’s get into it ✨

---

🌸 NAME 🌸

struct batadv_tvlv_hdr — the literal base tvlv header struct, no cap 💖

---

✨ SYNOPSIS ✨

Here’s the whole vibe, exactly as written:

struct batadv_tvlv_hdr {
    __u8 type;
    __u8 version;
    __be16 len;
 };

Look at her. Three fields. Zero drama. Main character energy 🫶

🦋 Members 🦋

• type — the tvlv container type, and yes bestie it points you at batadv_tvlv_type (see that one for the full lore) 👑
• version — the tvlv container version. It’s literally the version field. Slay 💅
• len — the tvlv container length. That’s the size, periodt 📏

🔥 SEE ALSO 🔥

So there’s a whole extended universe of batadv packets, enums, structs, and flags, and I’m not gonna gatekeep a single one. Keep scrolling, bestie, because this list is long and every single reference is staying 🫶

Like, that’s the whole page. Tiny struct, massive little reference ecosystem. Obsessed 💜

And the cute little sign-off: this page lives under ./include/uapi/linux, dated October 2026, and it’s still out here being struct batadv_tvlv_hdr(9). Periodt 🌈⭐
