💅 batadv_wifi_net_device_update — Kernel API Manual

okay so bestie, welcome to the manual page for batadv_wifi_net_device_update(9) 🦋 this one lives in the Kernel API Manual and honestly? it's giving "small function, big responsibilities" energy. let's get into it ✨

---

🌸 NAME 🌸

batadv_wifi_net_device_update — update wifi state of net_device

like… it updates the wifi state. of a net_device. that's the whole vibe 🎀

---

✨ SYNOPSIS ✨

void batadv_wifi_net_device_update (struct net_device *net_dev );

one function, one argument, void return because it doesn't need to hand you anything back — it just does the thing and leaves 💅

---

🫶 ARGUMENTS 🫶

• net_dev — the net_device to update in batadv_wifi_net_devices. that's it, that's the whole argument list, just your one little network device showing up to get its status refreshed 🌈

---

🔥 DESCRIPTION 🔥

okay so here's the tea ☕ the device only gets stored in batadv_wifi_net_devices when it could be identified as a wifi device. that's the entry requirement, no exceptions, the bouncer is checking IDs at the door 💀

and if the net_device is no longer a wifi device? it gets automatically removed from batadv_wifi_net_devices. not me ghosting the list the second the wifi vibe is gone 😭 it's self-cleaning, it's efficient, it's lowkey iconic.

so basically: wifi device → you're in the list 🫶 not a wifi device anymore → bye bestie, you're out 👋 and batadv_wifi_net_device_update is the one making that call.
