iavf_legacy_rx_hash(9)

💖 NAME 💖

iavf_legacy_rx_hash — bestie, this one sets the hash value in the skb ✨

(it lives in the Kernel API Manual, hi, welcome, come on in 🫶)

🎀 SYNOPSIS 🎀

void iavf_legacy_rx_hash (const struct iavf_ring *ring , __le64 qw0 ,
__le64 qw1 , struct sk_buff *skb , const struct libeth_rx_pt decoded_pt
);

🌸 ARGUMENTS 🌸

• ring — the descriptor ring, aka the whole vibe zone this is happening in 💅
• qw0 — quad word 0, yes it's literally called that 😭
• qw1 — quad word 1, the sequel, equally iconic 👑
• skb — the skb that's currently being received and modified, main character energy fr fr
• decoded_pt — the decoded packet type, the lore 🦋

---

✨ DESCRIPTION ✨

Okay so here's the tea 🍓: this function operates only on the VIRTCHNL_RXDID_1_32B_BASE legacy 32byte descriptor writeback format. That's it, that's the whole scope. No cap, it does not branch out, it does not freelance, it stays in its lane 💀

If you were hoping it'd work on some other descriptor format… nope bestie, it's giving very exclusive guest list 🙈
