iavf_flex_rx_hash(9)

💅 iavf_flex_rx_hash(9) 💅

okay bestie, welcome to the Kernel API Manual ✨ this one's a little function with one very specific job, and honestly? she knows exactly what she is. let's get into it 🫶

---

🌸 NAME 🌸

iavf_flex_rx_hash — set the hash value in the skb ✨

like, she literally just drops the hash into the skb. that's the whole gig. iconic, lowkey 🎀

---

🦋 SYNOPSIS 🦋

void iavf_flex_rx_hash (const struct iavf_ring *ring , __le64 qw1 ,
       struct sk_buff *skb , const struct libeth_rx_pt decoded_pt );

no cap, that's the exact signature, don't come for me 💀

---

🎀 ARGUMENTS 🎀

• ring — descriptor ring 💫 the whole setup she's working inside of
• qw1 — quad word 1 🌈 literally quad word 1, that's the whole description, iykyk
• skb — skb currently being received and modified 👑 this is the main character right here, the thing getting touched
• decoded_pt — decoded packet type 🔥 the packet type, already decoded for you, slay

---

💖 DESCRIPTION 💖

so here's the vibe check: this function only operates on the VIRTCHNL_RXDID_2_FLEX_SQ_NIC flexible descriptor writeback format. that's it. that's the whole scope. if you're not in that format, she's not the one for you, fr fr 🙈
