batadv_inte...set_mac_addr(9)

💅 batadv_interface_set_mac_addr — the glow-up page 💅

okay so real talk, this is a Kernel API Manual page for batadv_inte...set_mac_addr(9) and it's basically the makeover function for your mesh interface's MAC address. bestie, let's get into it ✨

---

✨ NAME ✨

batadv_interface_set_mac_addr — change the MAC address of a mesh interface 🎀

---

🦋 SYNOPSIS 🦋

int batadv_interface_set_mac_addr (struct net_device *dev , void *p );

that's the whole vibe check right there, no cap 👑

---

🌸 ARGUMENTS 🌸

• dev — the mesh interface to modify 💖 this is the main character, the one getting the new look
• p — pointer to a struct sockaddr holding the new MAC address 🫶 like, that's where the fresh address lives

---

🧚 DESCRIPTION 🧚

Replace the MAC address of the mesh interface. That's the whole errand, honestly 🎀

but wait, there's lore: if the mesh is already active, it also updates the local translation table entries for all configured VLANs so that the new MAC is announced and the old one is removed. it's giving "not just a glow-up, a whole rebrand" 😭💅 like every VLAN needs to hear about the new address, and the old one gets ghosted. iconic.

---

⭐ RETURN ⭐

0 on success or negative error number in case of failure 🥲 (we love a zero, we do not love a negative number, but it happens)
