igbvf_close(9)

💅 igbvf_close — the Kernel API Manual moment 🎀

okay bestie so you're looking at igbvf_close(9) from the Kernel API Manual and honestly? She's a whole vibe. Let's get into it ✨

---

🌸 NAME 🌸

igbvf_close — disables a network interface 🫶

Like, she literally turns the NIC off. That's the whole job. Iconic.

---

🦋 SYNOPSIS 🦋

int igbvf_close (struct net_device *netdev );

One argument, one return, zero drama. periodt.

---

💖 ARGUMENTS 💖

• netdev — the network interface device structure 💅 that's the thing you're shutting down, bestie, no cap

---

✨ DESCRIPTION ✨

So here's the tea ☕ — she returns 0, and that's it. This is not allowed to fail. Not "probably won't", not "usually doesn't" — not allowed. She's giving unbothered main character energy 🎀

The close entry point gets called when an interface is de-activated by the OS. The hardware is still under the driver's control at this point (lowkey important), but it needs to be disabled. So what happens is: a global MAC reset is issued to stop the hardware, and all transmit and receive resources are freed. Clean sweep, no crumbs left behind 🧹✨
