💖 iavf_open(9) 💖

okay bestie, welcome to the Kernel API Manual ✨ this little page is all about iavf_open — the function that gets called when a network interface is made active. yes, that's the whole vibe. let's get into it 🎀

✨ NAME ✨

iavf_open — Called when a network interface is made active 🌸

like, the moment your netdev gets its glow-up and goes live? that's this function. main character energy fr fr 💅

🦋 SYNOPSIS 🦋

int iavf_open (struct net_device *netdev );

(and yes, the spacing in there is exactly how the page has it — copy it verbatim, don't "fix" it 🙈)

🎀 ARGUMENTS 🎀

  • netdev — the network interface device structure. that's your netdev bestie, the whole device struct you're bringing to life 🫶

💜 DESCRIPTION 💜

okay so here's the tea ☕ this function returns 0 on success, and a negative value on failure — no cap, negative means something went wrong 😭

The open entry point is called when a network interface is made active by the system (IFF_UP). At this point, all the resources needed for transmit and receive operations are allocated, the interrupt handler is registered with the OS, the watchdog is started, and the stack is notified that the interface is ready 🔥

so basically: allocate tx/rx stuff, register the irq handler, kick off the watchdog, tell the stack "she's ready" — all in one iconic little call. the way that this one function does four things at once, honestly obsessed 👑

💅 SEE ALSO 💅

the kernel file itself lives at ./drivers/net/ethernet/intel/iavf/iavf_main.c — that's the source of truth, iykyk 🦋
