✨ txgbe_fdir_add_signature_filter ✨

okay so this is a page straight out of the Kernel API Manual, and bestie, we're about to get intimate with a signature hash filter 💅 no cap, it's giving "networking but make it cute".

---

🎀 NAME 🎀

txgbe_fdir_add_signature_filter — literally just adds a signature hash filter. that's it. that's the whole vibe 🦋

---

🌸 SYNOPSIS 🌸

int txgbe_fdir_add_signature_filter (struct wx *wx , union
txgbe_atr_hash_dword input , union txgbe_atr_hash_dword common , u8
queue );

like, she takes four things and returns an int. icon behaviour, honestly 👑

---

💖 ARGUMENTS 💖

• wx — pointer to hardware structure. yes she needs the hardware, this is not a drill 🔥
• input — the unique input dword. one of a kind, main character energy, no dupes allowed ✨
• common — the compressed common input dword. squeezed down and ready to go 🎀
• queue — queue index to direct traffic to. you're telling the traffic exactly where to go, like a tiny traffic director with a clipboard 🫶

---

⭐ RETURN ⭐

returns 0 on success and negative on failure. so if you see a negative number, that's your sign that things went 💀 — not in the fun way.
