ice_calc_vf_reg_idx(9)

💅 ice_calc_vf_reg_idx — a Kernel API Manual moment ✨

okay so bestie, welcome to the Kernel API Manual entry for ice_calc_vf_reg_idx(9) and honestly? it's giving "small function, big responsibility" 🎀 let's get into it.

---

✨ NAME ✨

ice_calc_vf_reg_idx — literally just calculate the VF's register index in the PF space 💖 that's the whole job. that's the assignment. she's doing one (1) thing and she's doing it.

---

🦋 SYNOPSIS 🦋

void ice_calc_vf_reg_idx (struct ice_vf *vf , struct ice_q_vector
*q_vector );

like, no cap, that's the signature. she returns void and takes two pointers. simple. iconic. periodt. 👑

---

🌸 ARGUMENTS 🌸

• vf — the VF you're calculating the register index for 🫶 she's the main character here, the whole reason we're gathered.
• q_vector — a q_vector that's associated to the VF ✨ so like, the q_vector has to actually belong to that VF, iykyk.

no defaults, no optional stuff, no null-check hand-holding spelled out in the page — you pass the VF, you pass the q_vector, you move on. 💀
