ice_vf_vsi_setup(9)

💅 ice_vf_vsi_setup(9) — or, "how to birth a VF VSI" 🎀

okay so real talk, bestie — this is a page from the Kernel API Manual, section 9. Yes, section 9. Very demure, very kernel. Let's get into it ✨

---

🌸 NAME 🌸

ice_vf_vsi_setup — Set up a VF VSI

(yes that's the whole name description. short. iconic. it ate and left no crumbs 💅)

---

✨ SYNOPSIS ✨

struct ice_vsi * ice_vf_vsi_setup (struct ice_vf *vf );

like, one function, one argument, one dream 🫶

---

🦋 ARGUMENTS 🦋

• vf — the VF you're setting the VSI up for. that's it. that's the whole parameter. she's got one job 💖

---

👑 DESCRIPTION 👑

okay so here's the tea ☕: if everything goes slay, you get back a pointer to the successfully allocated VSI struct. 🎉

but if it doesn't work out? returns NULL on failure. no VSI, no vibes, just NULL. 😭 lowkey devastating but that's the contract, fr fr.
