i40e_vc_get_pf_queue_id(9)

💖 i40e_vc_get_pf_queue_id(9) 💖

okay so welcome to the Kernel API Manual, bestie — section 9, the fun one. Today's main character is i40e_vc_get_pf_queue_id, and yes she's one of those tiny helper functions that lowkey holds the whole virtual-function situation together. Let's get into it 🎀

---

✨ NAME ✨

i40e_vc_get_pf_queue_id — and listen, the name section in the original source is literally just the name and a lonely dash 😭 no description, no nothing. Iconic in a mysterious way. Anyway: that's the function, that's the name, we move 🫶

---

🌸 SYNOPSIS 🌸

u16 i40e_vc_get_pf_queue_id (struct i40e_vf *vf , u16 vsi_id , u8
vsi_queue_id );

she takes three things and hands you back a u16. no cap, that's the whole vibe 💅

---

🦋 ARGUMENTS 🦋

• vf — pointer to the VF info. like, the little info card for the virtual function. you hand her the card, she does the rest 💖
• vsi_id — id of VSI as provided by the FW. the firmware gave it to you, don't lose it 🎀
• vsi_queue_id — vsi relative queue id, aka the queue number within that VSI. relative, not absolute, iykyk ✨

---

🌈 DESCRIPTION 🌈

return PF relative queue id 💫

that's it. that's the description. she converts your vsi-relative queue id into the PF-relative one and returns it. short, sweet, doing her one job flawlessly — main character energy, honestly 👑

like, that's the whole group chat. ate every single time 💅

---

quick heads up bestie: some of these have that leading double-underscore, like __i40e_getnum_vf_vsi_vlan_filters(9) — it's a different function from i40e_getnum_vf_vsi_vlan_filters(9), so pls don't @ me and don't merge them 🙈

🎀 the cute sign-off 🎀

this little page lives in the kernel tree at ./drivers/net/ethernet/intel/i40e, dated October 2026, and she's manual page i40e_vc_get_pf_queue_id(9) in the Kernel API Manual. go forth, get those queue ids, slay ✨💖🍓
