iavf_get_rxfh_key_size(9)

💅 iavf_get_rxfh_key_size — like, the RSS hash key size getter ✨

okay so real talk, this is a page straight out of the Kernel API Manual (iavf_get_rxfh_key_size(9)), and it's honestly so simple it's iconic. Sit down, bestie, this one's a quick read 🫶

---

🌸 NAME 🌸

iavf_get_rxfh_key_size — get the RSS hash key size. that's it. that's the whole vibe 💖

---

✨ SYNOPSIS ✨

u32 iavf_get_rxfh_key_size (struct net_device *netdev );

like, it takes one thing and gives you back a u32. no cap, that's the signature, copy it exactly or the compiler will absolutely humble you 😭

---

🎀 ARGUMENTS 🎀

• netdev — the network interface device structure. yes queen, the whole struct net_device *, she's the main character here 👑

---

⭐ RETURN ⭐

returns the RSS hash key size. that's the whole payoff, bestie — a u32 with the key size in it. slay 💅
