💅 iavf_extract_flex_rx_fields(9) 💅

okay so hi bestie 💖 this is the iavf_extract_flex_rx_fields(9) page from the Kernel API Manual, and it’s lowkey giving “tiny decoder function with main character energy.” No cap, it’s here to pull the important bits out of an Rx descriptor and make them make sense. ✨

---

🎀 NAME 🎀

iavf_extract_flex_rx_fields — extract fields from the Rx descriptor. It’s literally in the name, bestie, and yes it ate. 💅

---

🌸 SYNOPSIS 🌸

struct libeth_rqe_info iavf_extract_flex_rx_fields (const struct iavf_ring *rx_ring , const struct iavf_rx_desc *rx_desc );

---

🦋 ARGUMENTS 🦋

• rx_ring — the rx descriptor ring. That’s the ring we’re working with, bestie 🫶
• rx_desc — the descriptor to process. Yep, this is the one getting the full vibe-check treatment 💅

---

✨ DESCRIPTION ✨

okay so iavf_extract_flex_rx_fields() decodes the Rx descriptor and extracts relevant information including the size, VLAN tag, Rx packet type, end of packet field, and RXE field value. It’s giving “organized little field-extraction moment,” and honestly? Obsessed. 💖

The way that this function only operates on the VIRTCHNL_RXDID_2_FLEX_SQ_NIC flexible descriptor writeback format is so real — no cap, that’s its whole lane. 🦋

---

👑 RETURN 👑

fields extracted from the Rx descriptor. That’s the return vibe, bestie — it hands back the extracted fields, periodt. ✨
