ice_hash_moveout(9)

💅 ice_hash_moveout(9) — from the Kernel API Manual, section 9, bestie ✨

Okay so picture this: you're deep in the ice driver, you've got a VF (that's a Virtual Function, a whole little vibe of its own), and you need to move an RSS configuration out of the picture — but like, keep the context around. That's literally what this function does. It deletes an RSS configuration but keeps the context. Iconic behaviour, no notes. 🎀

---

✨ NAME ✨

ice_hash_moveout — Delete an RSS configuration (keep context) 🫶

---

🌸 SYNOPSIS 🌸

int ice_hash_moveout (struct ice_vf *vf , struct ice_rss_hash_cfg *cfg
);

It's giving int. It's giving two arguments. It's giving exactly what you typed, bestie, don't @ me. 💅

---

🦋 ARGUMENTS 🦋

• vf — your VF pointer, the main character of this whole situation 👑
• cfg — the RSS hash configuration that's getting moved out. Bye bestie, love you, mean it 🥺

---

⭐ RETURN ⭐

• 0 — slay, success! ✨ And yes, this includes the case where the thing was already absent. No drama, no error, just vibes.
• -ENOENT — nope, this happens if cfg is invalid or the VSI is missing. Lowkey a tragedy 😭
• -EBUSY — the hardware removal failed. Not the hardware acting up 💀 it's fine, it's fine, we're fine.

Lowkey the best part? Check ice_hash_moveback(9) if you ever need to, y'know, move it back. Bestie's got options. 💖
