ice_get_rx_hash(9)

💖 ice_get_rx_hash(9) — the Kernel API Manual glow-up 💖

okay so bestie, welcome to ice_get_rx_hash(9) — yes that's the section 9 kernel API manual, we're doing driver-internals errands today and honestly? it's giving "small function, big friend group" 🫶

---

✨ NAME ✨

ice_get_rx_hash — get the RX hash value from the descriptor, literally that's the whole job 💅

---

🌸 SYNOPSIS 🌸

u32 ice_get_rx_hash (const union ice_32b_rx_flex_desc *rx_desc );

like, you hand it a descriptor, it hands you back a u32, no drama, no cap ✨

---

🎀 ARGUMENTS 🎀

• rx_desc — the specific descriptor. that's it, that's the whole arg, she's a pointer to a const union ice_32b_rx_flex_desc and she's the main character of this function 🦋

---

💜 DESCRIPTION 💜

so what does it actually do? it returns the hash — if it's present. and if it's not present? you get 0. zero. nothing. the void. 😭 that's the entire contract, bestie, no hidden lore.

ngl the brevity is iconic. hash present → hash. hash absent → 0. periodt. 👑
