STRUCT BATADV_OGM_PACKET(9)

💖 struct batadv_ogm_packet(9) — the Kernel API Manual page, bestie edition 💖

okay so this is the struct batadv_ogm_packet page from the Kernel API Manual, and it's literally the ogm — that's the routing protocol packet, no cap. it's a struct definition, so we're gonna walk through every single member together, one by one, holding hands 🫶

---

✨ NAME ✨

struct batadv_ogm_packet — the ogm (routing protocol) packet. that's it, that's the whole vibe. 👑

---

🌸 SYNOPSIS 🌸

here's the whole struct, exactly as it lives, don't touch a single byte bestie:

struct batadv_ogm_packet {
    __u8 packet_type;
    __u8 version;
    __u8 ttl;
    __u8 flags;
    __be32 seqno;
    __u8 orig[ETH_ALEN];
    __u8 prev_sender[ETH_ALEN];
    __u8 reserved;
    __u8 tq;
    __be16 tvlv_len;
 };

she's giving "field order matters" energy and honestly? iconic. 💅

🎀 Members 🎀

okay so this is the part where we meet the cast. main character energy for every single one:

• packet_type — batman-adv packet type, and it's part of the general header. so she's not just a member, she's a team player. 🦋
• version — batman-adv protocol version, also part of the general header. yes, another header girlie. ✨
• ttl — time to live for this packet, and yup, part of the general header too. the header trio ate, fr fr. 🔥
• flags — contains routing relevant flags — see enum batadv_iv_flags. so if you're confused, that's where you go. iykyk. 🧚
• seqno — sequence identification. her whole job is keeping track of the sequence. slay. 🎀
• orig — address of the source node. like, where it came from, literally. 📍
• prev_sender — address of the previous sender. the previous one though, not the source, do not confuse them please 😭
• reserved — a reserved byte, and it's there for alignment. she's not doing much but she's doing it fabulously. 💀
• tq — transmission quality. the vibe check of the packet, lowkey. 🌈
• tvlv_len — length of tvlv data following the ogm header. so there's more stuff after the header and this is the length of it. noted bestie. 🍓

and that's the page bestie!! this one came out of the kernel file ./include/uapi/linux, dated October 2026, and it's filed under struct batadv_ogm_packet(9) in the Kernel API Manual. go be iconic with your packets, ily, bye!! 💅✨🦋🎀
