idpf_rx_sing...tract_fields(9)

✨ NAME ✨

okay so bestie, welcome to the Kernel API Manual, section 9 — this one's idpf_rx_singleq_extract_fields, and it does exactly one job: extract fields from the Rx descriptor. that's it. that's the whole vibe. 🎀

(also real quick — the header on this page is truncated to idpf_rx_sing...tract_fields(9) because man page headers have a character budget and honestly she ate what she could 💅)

🌸 SYNOPSIS 🌸

void idpf_rx_singleq_extract_fields (const struct idpf_rx_queue *rx_q ,
const union virtchnl2_rx_desc *rx_desc , struct libeth_rqe_info *fields
);

no return value, no drama — it's a void. she takes three things and gives you nothing back except knowledge. iconic behavior honestly.

🦋 ARGUMENTS 🦋

three little besties walk into a function:

• rx_q — the Rx descriptor queue. that's the queue we're pulling from, bestie. she's the whole context. 👑
• rx_desc — the descriptor to process. this is the actual thing we're cracking open to see what's inside. 🔥
• fields — storage for the extracted values. yeah, you bring your own bucket, she just fills it. no cap.

⚠️ heads up: rx_q is const and rx_desc is const — read-only energy. fields is not const because that's literally the output slot. don't come for her.
