💖 atl1c_close(9) — Kernel API Manual, bestie 💖

🌸 NAME 🌸

atl1c_close — Disables a network interface. periodt. 💅

🦋 SYNOPSIS 🦋

int atl1c_close (struct net_device *netdev );

🎀 ARGUMENTS 🎀

• netdev — network interface device structure. that’s the struct this close hook gets handed, iconic. 🫶

🔥 DESCRIPTION 🔥

Okay so atl1c_close returns 0, and this is not allowed to fail — like, the close path has to come through, no cap. 😭

The close entry point is called when an interface is de-activated by the OS. At that point the hardware is still under the driver’s control, but it needs to be disabled. A global MAC reset is issued to stop the hardware, and all transmit and receive resources are freed. That’s the cleanup arc, bestie — hardware stopped, resources freed, vibes intact. ✨
