i40e_ndo_set_vf_link_state(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, this is a page from the Kernel API Manual — section 9, kernel API, iykyk — all about the function i40e_ndo_set_vf_link_state. She's a little one. One job. We love a focused queen. 👑

✨ NAME ✨

i40e_ndo_set_vf_link_state —

so the manual is honestly kind of mysterious here. The dash is there, the description is not. That's the whole NAME section, no cap. Just the name and a lonely little dash. She said "figure it out." 💅

🌸 SYNOPSIS 🌸

int i40e_ndo_set_vf_link_state (struct net_device *netdev , int vf_id ,
int link );

that's the whole signature, cutie. returns an int, takes three lil arguments. copy it exactly if you're typing it out, mwah. 🎀

🎀 ARGUMENTS 🎀

  • netdev — the network interface device structure. it's the device. she's the main character, everyone else is a guest. 🫶
  • vf_id — the VF identifier. which VF we're talking about, literally just the ID. ⭐
  • link — the required link state. the state you want. the desired vibe check, but for a link. ✨

💖 DESCRIPTION 💖

okay so here's the entire tea: this function sets the link state of a specified VF, regardless of physical link state. 🦋

that's it. that's the bar. you pick a VF, you pick the link state, and it goes and sets it — and it does NOT care what the physical link state is doing at the time. no consultation, no vibes check with the hardware, it just does the thing. periodt. 🔥

bestie, read that "regardless of physical link state" part again. it's doing this regardless — that's the whole point of the function, so don't come for me if you wanted it to politely ask the physical link first. it does not. 😭

🌈 SEE ALSO 🌈

alright. deep breath. she has a LOT of friends. this is the group chat and everyone is invited, so let me name every single one of them, exactly, no skipping: 💜

  • Kernel file: ./drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c

and now, the entire crew:

like I said. HUGE group chat. every one of them is there, don't @ me, go read them if you want the lore. 📚✨

ok that's the whole page bestie, you ate that 💅

and the cute sign-off, because the footer deserves love too: this page lives with the i40e driver under ./drivers/net/ethernet/intel/i40e, and it's dated October 2026. so she's future-dated, she's iconic, she's got main character energy. go forth and set that link state. 🧚‍♀️💖🌸
