💅 idpf_rx_sin..._base_fields — Kernel API Manual ✨

okay bestie, so we're in the kernel API manual and today's main character is idpf_rx_sin..._base_fields (yes the name is truncated with ... in the header, that's just how she is, iykyk 🎀).

---

💖 NAME 💖

idpf_rx_singleq_extract_base_fields — literally just extracts fields from the Rx descriptor. that's the whole vibe. no cap.

---

✨ SYNOPSIS ✨

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

she's a void function, she takes two pointers, she does her thing. periodt. 🔥

---

🫶 ARGUMENTS 🫶

• rx_desc — the descriptor to process, aka the lil guy you're handing over 💌
• fields — storage for extracted values, aka where the good stuff gets put 🌸

---

🦋 DESCRIPTION 🦋

so what she does is: decode the Rx descriptor and pull out the relevant info, which includes the size and the Rx packet type. iconic behavior honestly 👑

⚠️ real talk though: this function only operates on the VIRTCHNL2_RXDID_1_32B_BASE_M base 32byte descriptor writeback format. that's it. that's the only format she fw. don't try to slide her anything else 💀
