ice_for_each_vf(9)

💅 ice_for_each_vf(9) 💅

okay bestie, welcome to the Kernel API Manual, section 9 — this one's a macro-flavored little loop-de-loop and it's honestly iconic once you get it. sit down, grab a strawberry 🍓, let's go.

---

✨ NAME ✨

ice_for_each_vf — loop your way through every single VF entry, one at a time, no skips, no cap 🫶

---

🌸 SYNOPSIS 🌸

ice_for_each_vf (pf , bkt , vf );

---

🎀 ARGUMENTS 🎀

• pf — pointer to the PF private structure, aka the main character of this whole operation 👑
• bkt — the bucket index used for the iteration, your little loop gremlin
• vf — pointer to the VF entry that's currently being processed in the loop, so like, the one you're on right now 💫

---

🦋 DESCRIPTION 🦋

so the bkt variable? it's an unsigned integer iterator that you use to traverse the VF entries. and here's the part everyone messes up: it is *not* guaranteed to be the VF's vf_id. not even a little bit. do not assume it is. like, don't even think about it 🙈. if you actually need the id number, go get it with vf->vf_id, periodt.

also, the caller is expected to be holding the table_lock mutex for the entire loop — the whole time, no dropping it halfway, no "brb". and use this iterator if your loop is long or if it might sleep 😴 (yes, that's the whole vibe check on when to pick this one).
