💅 iavf_extrac...cy_rx_fields(9) 💅

okay so this is a page straight out of the Kernel API Manual, and honestly? it's giving "small function, big responsibilities." let's get into it bestie 🫶

---

✨ NAME ✨

iavf_extract_legacy_rx_fields — bestie, this one pulls the fields out of the Rx descriptor 💖

---

🦋 SYNOPSIS 🦋

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

like yes, it returns a whole struct libeth_rqe_info — she's not just peeking, she's reporting back ✨

---

🎀 ARGUMENTS 🎀

• rx_ring — the rx descriptor ring, aka the venue where all this is happening 💅
• rx_desc — the descriptor to process. this is THE one, the main character of the moment 👑

---

🌸 DESCRIPTION 🌸

so what does she actually do? she decodes the Rx descriptor and extracts the relevant info, which includes:

• the size
• the VLAN tag
• the Rx packet type
• the end of packet field
• the RXE field value

no cap, that's the whole haul 💖

⚠️ important vibe check: this function only operates on the VIRTCHNL_RXDID_1_32B_BASE legacy 32byte descriptor writeback format. like, that's the only format she fw's with. don't come at her with anything else fr fr 😭

---

🧚 RETURN 🧚

the fields extracted from the Rx descriptor. that's it, that's the tea 🍓
