i40e_validate_mqprio_qopt(9)

💖 i40e_validate_mqprio_qopt — validate queue mapping info ✨

okay so welcome to the kernel API manual, section 9, aka i40e_validate_mqprio_qopt(9) 🫶 this page is short, it's sweet, and it's literally just "bestie, does this queue mapping actually make sense?" and honestly? we respect the focus. 👑

---

🌸 NAME 🌸

i40e_validate_mqprio_qopt — validate queue mapping info.

that's the whole assignment. no drama, no extra lore, just validation of queue mapping info. periodt. 💅

---

✨ SYNOPSIS ✨

int i40e_validate_mqprio_qopt (struct i40e_vsi *vsi , struct
       tc_mqprio_qopt_offload *mqprio_qopt );

so it hands you back an int, and it wants two things: a struct i40e_vsi * and a struct tc_mqprio_qopt_offload *. the spacing in that prototype is exactly how the manual prints it — not me, I am not touching it, that's sacred text 🙈

---

🦋 ARGUMENTS 🦋

• vsi — the VSI being configured 💖 like, the actual virtual thing in question that's getting set up. that's the setting.
• mqprio_qopt — queue parametrs 🎀 yes, "parametrs" — that's genuinely how the manual spells it and I'm keeping it, iconic behavior, no cap. this is your queue parameters struct, the thing getting the vibe check.

ngl, two arguments, zero options, zero environment variables — this page is minimalism and I'm obsessed 🦋

okay mwah that's the page!! 💖 this one came out of ./drivers/net/ethernet/intel/i40e and it's dated October 2026, and the manpage name is still i40e_validate_mqprio_qopt(9) because we don't rename icons ✨ go validate something, bestie 🎀🌸🦋
