ice_is_arfs_...perfect_flow(9)

🌸 NAME 🌸

okay so bestie, welcome to ice_is_arfs_using_perfect_flow from the Kernel API Manual — section 9, iykyk. The actual name line is:

ice_is_arfs_using_perfect_flow — check if aRFS has active perfect filters ✨

---

✨ SYNOPSIS ✨

Here’s the signature, copied exactly so nobody gets clowned:

bool ice_is_arfs_using_perfect_flow (struct ice_hw *hw , enum
       ice_fltr_ptype flow_type );

---

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure. That’s the hardware hookup, no cap 💅
• flow_type — flow type as Flow Director understands it. Speak its language, bestie 🦋

---

💅 DESCRIPTION 💅

Flow Director will query this function to see if aRFS is currently using the specified flow_type for perfect (4-tuple) filters. That’s the whole tea ☕ — it’s giving “hey, are we using this flow type for the perfect filters rn?” and this function is the vibe check for that exact question 🔥
