__idpf_rx_si...s_skb_fields(9)

💖 NAME 💖

okay so this is the Kernel API Manual page for __idpf_rx_si...s_skb_fields(9) — yes the title is a lil truncated, but the full function name is right here: __idpf_rx_singleq_process_skb_fields 💅

It does one iconic thing: populate skb header fields from the Rx descriptor. That’s the whole vibe ✨

---

✨ SYNOPSIS ✨

void __idpf_rx_singleq_process_skb_fields (struct idpf_rx_queue *rx_q ,
struct sk_buff *skb , const union virtchnl2_rx_desc *rx_desc , u16 ptype
);

---

🫶 ARGUMENTS 🫶

okay bestie, here’s the cast of characters:

• rx_q — the Rx ring that’s being processed 🌀
• skb — pointer to the current skb that’s getting populated 🎀
• rx_desc — the descriptor for the skb 📜
• ptype — the packet type 🏷️

---

🌸 DESCRIPTION 🌸

So what’s the tea? This function checks the ring, the descriptor, and the packet information — all three — in order to populate the hash, checksum, VLAN, protocol, and other fields inside the skb. It’s literally giving “field makeover montage” for your skb, no cap 💅✨
