idpf_stop(9)

💅 idpf_stop(9) — the Kernel API Manual page, bestie edition 🎀

okay so first of all, hi, welcome to idpf_stop(9) from the Kernel API Manual — yes the whole page is about one function and honestly she deserves it 💖

---

✨ NAME ✨

idpf_stop — literally just disables a network interface. that's the whole job. no cap 🫶

---

🌸 SYNOPSIS 🌸

int idpf_stop (struct net_device *netdev );

one function, one arg, int coming back at cha. iconic behavior ⭐

---

🦋 ARGUMENTS 🦋

• netdev — the network interface device structure. that's the netdevice girlie in question, the one we're about to put in time-out 🙈

---

🔥 DESCRIPTION 🔥

okay so picture this: the OS de-activates an interface, and the netdevice drops into the DOWN state. that's the moment the stop entry point gets called. it's like the lights going off at the sleepover but the mess is still there 😭

here's the important part, so listen up: the hardware is still under the driver's control, but the netdev interface itself is disabled. so like, the driver still has the keys 🔑 but the interface is grounded. periodt.

and the return value? success only. she is not allowed to fail. that's not a vibe check she can flunk — failing isn't even on the menu 💀
