i40e_free_vf_res(9)

🌸 i40e_free_vf_res — Kernel API Manual, section 9 🌸

Okay bestie, so this is i40e_free_vf_res(9) — a page out of the Kernel API Manual, section 9 (yes, the kernel developer's manual, we're in the big leagues now). It's a tiny little function page, so grab a boba and let's get into it, because it's genuinely short and I refuse to pad it 💅

---

✨ NAME ✨

i40e_free_vf_res — and honestly? That's it. The description slot on this one is empty, bestie. The man page authors really said "the name is the description" and clocked out 🎀 no tea, no shade.

---

🦋 SYNOPSIS 🦋

void i40e_free_vf_res (struct i40e_vf *vf );

That's the whole signature. Returns void, takes one pointer, no drama, main character energy only 🔥

---

🎀 ARGUMENTS 🎀

• vf — pointer to the VF info (the struct i40e_vf). That's the whole argument list, babes. One pointer. It's giving minimalist. ✨

---

💖 DESCRIPTION 💖

It frees VF resources.

That's the entire description. "free VF resources." Two words and a vibe 😭 Like the original page was written at 3am before a deadline and honestly? Respect. It's short, it's useful, it's literally the whole point of the function. The way that a function called i40e_free_vf_res frees VF res... iconic, no notes 🫶

So: you hand it a struct i40e_vf * and it frees up that VF's resources. If you were hoping for a novel, sorry bestie, this page is a haiku. 🌸

👑 SEE ALSO 👑

Okay so this is where the page pops off. The DESCRIPTION is two words, but the SEE ALSO section is a whole friend group — a full roster, a group chat with 96 members and you're the admin. All (9) sections, all in the kernel's i40e driver. Here we go, no cap, every single one:

Like, the way the DESCRIPTION gave us literally four words and then SEE ALSO served us an entire banquet? Ate. 🔥👑

Ngl bestie, if you're actually here to understand the i40e VF lifecycle, the move is to read the source file ./drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c and then hop around this list — that's literally why it's here. 🧚

💜 Alright, that's the whole page, bestie — short and sweet, just like the function. This one's from the Kernel API Manual, sourced out of ./drivers/net/ethernet/intel/i40e, dated October 2026. Periodt. Slay, go free some VF resources responsibly 🎀✨🦋
