💅 batadv_wifi_...device_event(9) — Kernel API Manual, but make it cute

Okay bestie, so we're in the Kernel API Manual today and this page is batadv_wifi_...device_event(9). Yes the name is doing the absolute most with those ellipsis dots, we love a dramatic abbreviation. Let's get into it 💖

---

✨ NAME ✨

batadv_wifi_net_device_event — the function that handles network events for batadv_wifi_net_devices. That's the whole vibe: something happens to a net device, and this lil hero shows up to deal with it 🫶

---

🌸 SYNOPSIS 🌸

void batadv_wifi_net_device_event (unsigned long event , struct
net_device *net_dev );

Two args, void return, no cap. It literally just runs the event and dips 😌

---

🎀 ARGUMENTS 🎀

• event — an enum netdev_cmd value, i.e. the actual event we're here to handle. This is the main character of the call, fr fr 👑
• net_dev — a struct net_device * pointing at the net_device that needs updating over in batadv_wifi_net_devices. Bestie needs her info refreshed ✨

🦋 SEE ALSO 🦋

Everything in this section lives in the kernel file ./net/batman-adv/hard-interface.c — that's the home base, the whole neighborhood 🏡

Also note the double underscore on __batadv_get_real_netdev(9) — that's not a typo, that's a whole different function from batadv_get_real_netdev(9). Don't come for me, okay, I'm just reading the manpage 😭
