STRUCT BATADV_UNICAST_4ADDR_PACKET(9)

💖 struct batadv_unicast_4addr_packet(9) — extended unicast packet 💖

okay so first things first, bestie: this is a page from the Kernel API Manual, and it's all about one little struct, struct batadv_unicast_4addr_packet. She's giving extended unicast packet energy and honestly? iconic. 🦋

---

✨ NAME ✨

struct batadv_unicast_4addr_packet — the extended unicast packet. that's her. that's the whole vibe. 💅

---

🌸 SYNOPSIS 🌸

here's the glow-up in full, no cap, copy it exactly:

struct batadv_unicast_4addr_packet {
    struct batadv_unicast_packet u;
    __u8 src[ETH_ALEN];
    __u8 subtype;
    __u8 reserved;
 };

like look at her. four fields. main character energy from top to bottom. 🔥

🎀 Members 🎀

breaking it down field by field, because you deserve to know:

• u — the common unicast packet header. she's the blueprint, the og, the foundation. everything else is just accessorizing. 👑
• src — address of the source. literally who sent this. the ETH_ALEN-length receipts. 📬
• subtype — packet subtype. she's got layers, okay? there's a whole taxonomy happening here. iykyk. 💫
• reserved — reserved byte for alignment. not me defending a whole byte just so everything lines up pretty 😭 but fr fr, alignment is self-care. 🫶

ngl bestie, go read the neighbors too — the struct never travels alone. 💜
