e1000_close(9)

💅 e1000_close(9) — like, the kernel API manual page, bestie

okay so this is e1000_close(9) from the Kernel API Manual, and honestly? she's short, she's sweet, she shuts down network interfaces for a living. let me tell you everything 🎀

---

✨ NAME ✨

e1000_close — disables a network interface. that's it. that's her whole job. iconic behavior fr fr 💖

---

✨ SYNOPSIS ✨

int e1000_close (struct net_device *netdev );

---

✨ ARGUMENTS ✨

• netdev — the network interface device structure 🦋. yes, that's the whole argument list, we love a low-maintenance queen.

---

✨ DESCRIPTION ✨

she returns 0, bestie. no cap. this one is not allowed to fail — like, failure isn't even on the table, it's not in her vocabulary 💅

so here's the tea ☕: 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 that point, but it needs to be disabled. so what happens? a global MAC reset gets issued to stop the hardware, and then all the transmit and receive resources are freed. clean. effortless. main character energy 👑

lowkey a whole squad 💀 but that's the list, exactly as it was handed to me, no edits, no skipping, periodt.

okay and before i go — cute lil sign-off time 🎀🌸 the source line on this one is ./drivers/net/ethernet/intel/e... (yes it's truncated in the footer, that's just how she's printed, don't @ me 🙈) and the date is October 2026, so mark your calendars bestie. that's the whole page, you ate it up, ily, bye ✨💜
