💖 ixgbe_atr_compute_perfect_hash_82599(9) 💖

okay so bestie, this page is straight out of the Kernel API Manual, and we're talking about the iconic ixgbe_atr_compute_perfect_hash_82599(9). it's giving kernel-level main character energy, and we're gonna get into it 💅

---

🌸 NAME 🌸

ixgbe_atr_compute_perfect_hash_82599 — Compute the perfect filter hash

---

✨ SYNOPSIS ✨

void ixgbe_atr_compute_perfect_hash_82599 (union ixgbe_atr_input *input
, union ixgbe_atr_input *input_mask );

---

🎀 ARGUMENTS 🎀

• input — the input bitstream we're computing the hash on, periodt 💖
• input_mask — the mask for the input bitstream, iykyk 🎀

---

🦋 DESCRIPTION 🦋

okay so this function has two main purposes, and it ate both of them. first, it applies the input_mask to the atr_input, which gives you a cleaned up atr_input data stream. secondly, it computes the hash and stores it in the bkt_hash field at the end of the input byte stream. this way it'll be available for future use without needing to recompute the hash — lowkey convenient, fr fr 💅
