💅 batadv_interface_add_vid(9) — a Kernel API Manual moment ✨

okay so bestie, welcome to the batadv_interface_add_vid(9) page — part of the Kernel API Manual, and honestly it's giving "small function, big responsibilities" energy 🎀

---

🌸 NAME 🌸

batadv_interface_add_vid — the ndo_add_vid API implementation. that's it, that's the whole name, and it ate 💅

---

✨ SYNOPSIS ✨

int batadv_interface_add_vid (struct net_device *dev , __be16 proto ,
       unsigned short vid );

look at that signature. iconic. no notes 👑

---

🫶 ARGUMENTS 🫶

• dev — the netdev of the mesh interface. the main character of this whole operation fr fr.
• proto — protocol of the vlan id. it's __be16 bestie, keep up 💖
• vid — identifier of the new vlan. an unsigned short, and yes it's literally the whole point of the function.

---

🦋 DESCRIPTION 🦋

so here's the vibe: this thing sets up all the internal structures needed for handling the new vlan on top of the mesh interface. all of them. not some, not most — all. it's doing the behind-the-scenes work so the vlan can actually exist up there in the mesh interface. lowkey underrated, highkey essential 🌈

---

⭐ RETURN ⭐

• 0 on success 🎉
• a negative error code in case of failure 😭

that's the whole contract. simple, clean, slay.
