STRUCT BATADV_ELP_PACKET(9)

🦋 struct batadv_elp_packet(9) 🦋

okay bestie so you're reading the Kernel API Manual and this page is literally all about struct batadv_elp_packet — the elp (neighbor discovery) packet ✨ ngl it's a whole vibe, small but iconic.

🌸 NAME 🌸

struct batadv_elp_packet — elp (neighbor discovery) packet 💅

---

✨ SYNOPSIS ✨

here's the whole glow-up, no changes, copy-pasted with love:

struct batadv_elp_packet {
    __u8 packet_type;
    __u8 version;
    __u8 orig[ETH_ALEN];
    __be32 seqno;
    __be32 elp_interval;
};

she's compact, she's cute, she's five fields of pure main character energy 🎀

👑 Members 👑

okay so let's meet the cast, fr fr:

• packet_type — batman-adv packet type, part of the general header. it's giving "hello, i am a packet" 🫶
• version — batman-adv protocol version, part of the general header. gotta know what era we're in 💖
• orig — originator mac address. the who-is-this of it all 🦋
• seqno — sequence number. it's a counter, it counts, it slays 🔥
• elp_interval — currently used ELP sending interval in ms. timing is everything, periodt ⏱️

can't just mention one, she brought her whole friend group 😭 (kernel file ./include/uapi/linux/batadv_packet.h and all these besties):

and that's a wrap, bestie 🎀 this lil gem lives in ./include/uapi/linux, dated October 2026, and it's literally iconic — go forth and vibe check those packets 🌈💖
