idpf_rx_sin..._flex_fields(9)

💅 idpf_rx_sin..._flex_fields — Kernel API Manual, section 9 🎀

okay bestie so picture this: you're deep in the kernel, section 9 of the Kernel API Manual, and this little function is literally the flex — no cap, "flex" is in the name. It lives in ./drivers/net/ethernet/intel/idpf so you already know it's giving Intel networking main character energy. Let's get into it ✨

---

🌸 NAME 🌸

idpf_rx_singleq_extract_flex_fields — pulls fields out of the Rx descriptor. that's it, that's the vibe 🫶

---

🦋 SYNOPSIS 🦋

void idpf_rx_singleq_extract_flex_fields (const union virtchnl2_rx_desc
*rx_desc , struct libeth_rqe_info *fields );

it returns void, so like… it's not gonna hand you a value back, bestie. it just does the thing 💅

---

🎀 ARGUMENTS 🎀

• rx_desc — the descriptor you want processed. the thing being decoded, the moment itself 👑
• fields — storage for the extracted values. this is where the good stuff lands 🍓

---

✨ DESCRIPTION ✨

So what does it actually do? It decodes the Rx descriptor and extracts the relevant info, including the size and the Rx packet type. that's the whole assignment, and it ate 🔥

⚠️ hold up — important caveat, don't skip this: this function only operates on the VIRTCHNL2_RXDID_2_FLEX_SQ_NIC flexible descriptor writeback format. like, that's the only format it'll flex with. anything else and you're on your own 🙈
