e1000e_open(9)

📦 version 7.3.1, in nixpkgs unstable

💖 e1000e_open(9) 💖

okay so bestie, welcome to the Kernel API Manual page for e1000e_open — the function that literally wakes your network interface up 🌸 This one's short but she's important, and we're gonna get into it.

✨ NAME ✨

e1000e_open — called when a network interface is made active 🦋

✨ SYNOPSIS ✨

int e1000e_open (struct net_device *netdev );

✨ ARGUMENTS ✨

  • netdev — the network interface device structure 🫶 that's it, that's the one argument, she's low maintenance

✨ DESCRIPTION ✨

So here's the vibe check: she returns 0 on success, and a negative value on failure. No cap, that's the whole contract 😭

The open entry point gets called when a network interface is made active by the system — that's IFF_UP, iykyk 👑

At this point all the resources needed for transmit and receive operations are allocated, the interrupt handler is registered with the OS, the watchdog timer is started, and the stack is notified that the interface is ready ✨ so like, four whole things happen and they're all listed above, and I'm not skipping a single one of them because that would be a crime 💅

Fr fr, this is the main character moment where the interface goes from "napping" to "actually doing stuff." Iconic behavior honestly 💀

✨ SEE ALSO ✨

Okay bestie, buckle up, because the SEE ALSO list is long and I am obsessed with how thorough it is 🍓

First off, the kernel file:

  • Kernel file ./drivers/net/ethernet/intel/e1000e/netdev.c

And now the whole group chat of related functions — every single one, in order, no skips 🙈

👑 that's every single one, bestie. I counted, I listed, I did not cut a single (9). You're welcome 💜
