ixgbe_close(9)

📦 version 7.3.1, in nixpkgs unstable

💖 ixgbe_close — the kernel API manual, bestie edition 💖

OK so you're reading ixgbe_close(9) from the Kernel API Manual and honestly? Slay. Let's get into it 💅

✨ NAME ✨

ixgbe_close — disables a network interface. That's it, that's the whole vibe. She shuts it down 🫶

🌸 SYNOPSIS 🌸

int ixgbe_close (struct net_device *netdev );

🎀 ARGUMENTS 🎀

  • netdev — the network interface device structure. Yeah. The whole device. Her. 👑

💜 DESCRIPTION 💜

Okay so first thing, the way this function is giving immovable object: it returns 0, and it is not allowed to fail. No cap. Zero. Always. She does not miss 😭

So here's the lore: the close entry point gets called when an interface is de-activated by the OS. And like — the hardware is still under the driver's control, right? But it needs to be disabled. So we're not yeeting the hardware out of existence, we're just... putting her to sleep 💤

How? A global MAC reset is issued to stop the hardware, and then all transmit and receive resources are freed. Everything. Freed. Spring cleaning era 🌸✨

🦋 SEE ALSO 🦋

The kernel file lives at ./drivers/net/ethernet/intel/ixgbe/ixgbe_main.c — go say hi to her, she has all the lore 🧚

And now, the friend group. Yes, all of them. Every single one. I am not skipping a single mutual, that would be so rude 💀

Bestie I counted them twice so you don't have to. Every name, intact, no edits. 🫡

Sign-off time, mwah 💋
