💅 ice_vc_fdir_param_check(9)

okay so bestie, welcome to the Kernel API Manual 🎀 — we're looking at ice_vc_fdir_param_check(9) today and honestly? she's a vibe checker. a literal vibe checker. let's get into it ✨

---

🌸 NAME

ice_vc_fdir_param_check — no cap, that's the whole name, the original manpage didn't give us a tagline so we're not inventing one 🙈

---

🦋 SYNOPSIS

int ice_vc_fdir_param_check (struct ice_vf *vf , u16 vsi_id );

---

💖 ARGUMENTS

• vf — pointer to the VF structure 👑 (yes, she's a pointer, treat her with respect)
• vsi_id — the VF relative VSI ID 🫶

---

✨ DESCRIPTION

So what does she actually do? She checks three things, periodt:

• that the VSI ID is valid ✅
• the PF's state ✅
• the VF's state ✅

that's it. that's the whole job. lowkey iconic for how focused she is 💅

---

🔥 RETURN

• 0 on success 🎉
• -EINVAL on error 😭
