i40e_get_link_status(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, this is a page from the Kernel API Manual (i40e_get_link_status(9)) and honestly? it's a little baddie. it does exactly one thing and it does it iconically. let's get into it 🦋

✨ NAME ✨

i40e_get_link_status — get status of the HW network link 🌐

like… is the cable plugged in or not. that's the whole vibe check.

✨ SYNOPSIS ✨

int i40e_get_link_status (struct i40e_hw *hw , bool *link_up );

look at her. one struct pointer, one bool pointer, returns an int. she's neat, she's tidy, she's serving 🫶

✨ ARGUMENTS ✨

  • hw — pointer to the hw struct 💜 literally just your hardware struct, hand her over
  • link_up — pointer to a bool (true/false = linkup/linkdown) — this is where the answer lands, no cap

✨ DESCRIPTION ✨

so the variable link_up comes back true if the link is up, and false if the link is down. that's it, that's the tea 🍓

⚠️ IMPORTANT bestie please read this part — the variable link_up is invalid if the returned value of status is != 0. like, if status isn't zero, do NOT trust link_up. she's not giving reliable info in that case, she's just giving chaos 💀 so check that return value first, fr fr.

Side effect: LinkStatusEvent reporting becomes enabled ✨ ooh she's not just reading, she's flipping a switch. main character energy honestly 👑

✨ SEE ALSO ✨

okay so this is the part where the manpage just lists literally everyone she knows. 127 besties. no i did not skip any, we're doing all of them, this is the group chat 🌈

and the kernel file she lives in is ./drivers/net/ethernet/intel/i40e/i40e_common.c — that's her address, that's her home 🏡💅

aaaand that's the whole page bestie, you ate it, go check a link status and slay 💖

sign-off szn 🎀 this lil beauty comes from ./drivers/net/ethernet/intel/i40e, dated October 2026, and yes it's still i40e_get_link_status(9) — same icon, same manual, same energy. mwah 😭💜
