💅 ice_arfs_is_perfect_flow_set — Kernel API Manual ✨

okay so bestie, welcome to the kernel API manual, this one's a lil function check-in and honestly it's kinda iconic 🎀

---

🌸 NAME 🌸

ice_arfs_is_perfect_flow_set — literally just checks whether the perfect flow is set 👑

---

✨ SYNOPSIS ✨

bool ice_arfs_is_perfect_flow_set (struct ice_hw *hw , __be16 l3_proto ,
u8 l4_proto );

---

🦋 ARGUMENTS 🦋

• hw — a pointer to the HW structure, bestie 🫶 it's giving "here's where all the hardware tea lives"
• l3_proto — either ETH_P_IP or ETH_P_IPV6, and it's in network order, no cap 🌈
• l4_proto — either IPPROTO_UDP or IPPROTO_TCP, pick your fighter 💀

---

💖 DESCRIPTION 💖

so the vibe here is: we only support perfect (4-tuple) filters for aRFS, periodt ✋💅

this function is the lil bestie that lets aRFS check if those perfect (4-tuple) flow rules are currently in place by Flow Director 👑✨ like it's not doing the work, it's just confirming the work is out there living its main character life 🌟
