STRUCT BATADV_UNICAST_PACKET(9)

🦋 struct batadv_unicast_packet(9) 🦋

okay bestie, so this page lives in the Kernel API Manual and it's literally all about one little struct: struct batadv_unicast_packet — the unicast packet for network payload. yes, THAT one. come on, let's get into it 💅

---

✨ NAME ✨

struct batadv_unicast_packet — unicast packet for network payload 🎀

---

🌸 SYNOPSIS 🌸

here's the whole shape of it, no cap, exactly as it is:

struct batadv_unicast_packet {
    __u8 packet_type;
    __u8 version;
    __u8 ttl;
    __u8 ttvn;
    __u8 dest[ETH_ALEN];
 };

five lil fields, all __u8, plus that dest array. it's giving tiny but mighty, honestly 🫶

---

💖 Members 💖

every field, one by one, because we do NOT skip:

• packet_type — the batman-adv packet type, and it's part of the general header. so it's not doing a solo career, it's in the group chat 🫂
• version — the batman-adv protocol version, also part of the general header. same deal, team player energy.
• ttl — time to live for this packet, and yup, part of the general header too. the way all three of these are just living in the general header? iconic.
• ttvn — translation table version number. that's the whole description, don't come for me, that's literally what it is 💅
• dest — originator destination of the unicast packet. i.e. where this thing is actually headed. main character destination, fr fr 👑
