txgbe_close(9)

💅 txgbe_close(9) — like, the Kernel API Manual page you actually wanna read ✨

okay so bestie, welcome to txgbe_close, one of the pages from the Kernel API Manual, and honestly? she's short, she's sweet, she's the cleanup queen of the txgbe driver 🎀

✨ NAME ✨

txgbe_close — Disables a network interface 🫶 (yes that's literally the whole vibe, she shuts the thing DOWN)

---

🌸 SYNOPSIS 🌸

int txgbe_close (struct net_device *netdev );

---

🦋 ARGUMENTS 🦋

• netdev — the network interface device structure 💖 like, the actual thing you're closing, bestie

---

🔥 DESCRIPTION 🔥

okay so first thing's first: this function returns 0, and no cap, it is not allowed to fail. Periodt. It just doesn't get the option to flop 😭

So here's the tea 🍓 — the close entry point gets called when an interface is de-activated by the OS. And the important detail? The hardware is still under the driver's control at that moment, it just needs to be disabled. She's not gone, she's just... off duty 💅

So what actually happens: a global MAC reset is issued to stop the hardware, and then all transmit and receive resources are freed ✨ it's giving responsible main character energy — she cleans up after herself, we love to see it 👑

🧚 lowkey important: the reset is what stops the hardware. Don't skip her little ritual, bestie 🙈
