ice_lb_vsi_setup(9)

📦 version 7.3.1, in nixpkgs unstable

✨ ice_lb_vsi_setup — the loopback VSI glow-up ✨

okay so bestie, we're in the Kernel API Manual, section 9 today, and this function is named ice_lb_vsi_setup(9) — say that three times fast, iykyk. It's the Intel ice driver's little corner of the kernel, and honestly it's giving "small function, big friend group" energy. Let's go 💅

🌸 SYNOPSIS 🌸

struct ice_vsi * ice_lb_vsi_setup (struct ice_pf *pf , struct
ice_port_info *pi );

like, look at that return type — a struct ice_vsi *, a whole pointer, living its best life. periodt.

🎀 ARGUMENTS 🎀

  • pf — the board private structure. your classic "everything about this board lives here" situation, no cap.
  • pi — a pointer to the port_info instance. the port's own little info drop, fr fr.

🦋 DESCRIPTION 🦋

So what does it actually do? It sets you up a loopback VSI — and on success it hands back a pointer to the successfully allocated VSI software struct like it's passing you a folded note in class 🫶.

On failure? It returns NULL. literally nothing. the void. the group chat left you on read 💀. So like, always vibe check your return value before you dereference it, bestie — that's not me being dramatic, that's just the description.

👑 SEE ALSO 👑

first up, the source of truth, the origin story, the main character itself:

Kernel file ./drivers/net/ethernet/intel/ice/ice_main.c

and now… the entire extended friend group 😭 this is the whole ice squad, and I'm listing every single one of them because nobody gets left out:

like… that's the whole roster 😭 every single one accounted for, nobody's getting iced out (pun fully intended 🧊).

And that's the page, bestie 💖 no warnings, no exit statuses, no env vars — this one's a clean little read. don't overthink it, just check your return pointer.

kisses and closing notes 🎀 — this gem lives in ./drivers/net/ethernet/intel/ice, it was dated October 2026, and the page you just read is ice_lb_vsi_setup(9). slay, go read the next one 💜🦋
