STRUCT IWL_RX_TRANSFER_DESC(9)

💅 struct iwl_rx_transfer_desc 💅

okay so this is a page from the Kernel API Manual, bestie — like literally the kernel's own lil group chat for driver devs. and today's main character is struct iwl_rx_transfer_desc, which the manpage just straight-up calls a "transfer descriptor". that's it. that's the whole name section. iconic minimalism, no notes ✨

---

✨ NAME ✨

struct iwl_rx_transfer_desc — transfer descriptor 🎀

that's the vibe. it's a descriptor. it transfers. we move 🦋

---

🌸 SYNOPSIS 🌸

here's the whole struct, character-for-character, no cap:

struct iwl_rx_transfer_desc {
    __le16 rbid;
    __le16 reserved[3];
    __le64 addr;
 };

look at her. three fields, extremely cunty layout, very demure, very mindful 💅

okay so let's meet the cast, one by one:

• rbid — the unique tag of the buffer. think of it as the buffer's @ handle, its little name tag so everybody knows which one it is 🏷️
• reserved — literally just reserved. it's reserved. it's being reserved. do not touch, she's saving that seat 🙈
• addr — a ptr to the free buffer start address. yes the manpage literally says "ptr to free buffer start address" and yes we're keeping it exactly like that 💖

lowkey the whole page is just a lil struct in the intel iwlwifi driver, but honestly? she's doing the work. respect the descriptor 🫡
