STRUCT BATADV_OGM2_PACKET(9)

💅 struct batadv_ogm2_packet(9) — the ogm2 packet, bestie ✨

okay so this is a page from the Kernel API Manual, and it's literally all about struct batadv_ogm2_packet — aka the ogm2 (routing protocol) packet 🦋. yes that's the whole NAME section, she's short and iconic and we respect that.

✨ SYNOPSIS ✨

here's the whole struct, copy it exactly, no edits, she's perfect:

struct batadv_ogm2_packet {
    __u8 packet_type;
    __u8 version;
    __u8 ttl;
    __u8 flags;
    __be32 seqno;
    __u8 orig[ETH_ALEN];
    __be16 tvlv_len;
    __be32 throughput;
 };

🎀 Members 🎀

okay bestie, field-by-field tour, let's go 💖

• packet_type — the batman-adv packet type. she's part of the general header, main character energy 👑
• version — the batman-adv protocol version. also part of the general header, matching set vibes ✨
• ttl — time to live for this packet. yep, general header again, she belongs there 🫶
• flags — reserved for routing relevant flags. and rn? currently always 0. no cap, that's just how it is 💀
• seqno — the sequence number. simple, elegant, slay 🌸
• orig — the originator mac address. that's ETH_ALEN bytes of "who dis" 🦋
• tvlv_len — length of the appended tvlv buffer, and ngl it's in bytes, don't forget 🙈
• throughput — the currently flooded path throughput. she's giving bandwidth gossip, iykyk 🔥

and that's the whole page, bestie 🧚💜 this one lives at ./include/uapi/linux and the version/date tag says October 2026 — so like, slight time traveler moment ⭐ go read the other packet structs, they're all in the group chat too 🍓✨
