atl1e_open(9)

📦 version 7.3.1, in nixpkgs unstable

okay so welcome to the atl1e_open(9) page from the Kernel API Manual — we're talking about the “network interface is made active” moment, and honestly? main-character activation arc 💅.

✨ NAME ✨

atl1e_open — called when a network interface is made active. That’s the whole name-section slay: this is the open entry point, and it’s literally the “she’s up” moment 🫶.

🌸 SYNOPSIS 🌸

int atl1e_open (struct net_device *netdev );

Here’s the signature in all its precise, int-returning glory, bestie ✨.

🎀 ARGUMENTS 🎀

  • netdev — network interface device structure. That’s the network interface device structure, periodt. She’s the interface being made active, so main character energy is fully justified 💖.

🔥 DESCRIPTION 🔥

Return situation: 0 on success, negative value on failure. No cap — a clean 0 means success, a negative value means failure, and that’s the whole return vibe fr fr.

The open entry point gets called when the system makes a network interface active (IFF_UP). At that point, the transmit and receive operations get all the resources they need allocated, the interrupt handler gets registered with the OS, the watchdog timer gets started, and the stack gets notified that the interface is ready.

So yeah, this function is doing a lot: resources allocated for transmit and receive, interrupt handler registered with the OS, watchdog timer started, and the stack told that the interface is ready. It’s giving “everything’s set, we’re officially open” ✨.
