batadv_send_unicast_skb(9)

💅 batadv_send_unicast_skb(9) — like, the kernel API manual bestie ✨

okay so hi, this is the manual page for batadv_send_unicast_skb(9) from the Kernel API Manual — section 9, obvs. it's giving "one small function, whole lotta lore," and honestly? we're obsessed. let's get into it 🫶

---

✨ NAME ✨

batadv_send_unicast_skb — send a unicast packet to a neighbor. that's it, that's the vibe. one packet, one neighbor, no cap 💌

---

🦋 SYNOPSIS 🦋

int batadv_send_unicast_skb (struct sk_buff *skb , struct batadv_neigh_node *neigh );

---

🎀 ARGUMENTS 🎀

• skb — the packet that's gonna be transmitted, bestie. important deets: it comes with a batadv header and no outer eth header. like, it's already dressed for the party, just not the outer layer 💅
• neigh — the neighbor that gets to be the next hop to the destination. main character of the routing moment fr fr 🌸

---

⭐ RETURN ⭐

so if something goes wrong, you get a negative errno code back. simple.

but here's the part where you need to listen: a success does not guarantee the frame will actually be transmitted 😭 it may still get dropped due to congestion or traffic shaping. so yeah — success means "we tried," not "it arrived." lowkey humble of it ngl 💀
