STRUCT IL_TFD_TB(9)

💅 struct il_tfd_tb(9) — Kernel API Manual, bestie ✨

okay so picture this: we're deep in the iwlegacy wireless driver, and there's this lil struct living its best life in ./drivers/net/wireless/intel/iwlegacy/common.h and it's called struct il_tfd_tb, and today we're gonna understand it fr fr 🫶 (also hi, this is the struct il_tfd_tb(9) page from the Kernel API Manual, welcome 💖)

---

🌸 NAME 🌸

struct il_tfd_tb — no description given in the original, she's mysterious like that 🙈 (the NAME section literally just trails off after the dash, so we're not gonna invent lore, ngl)

---

✨ SYNOPSIS ✨

struct il_tfd_tb {
    __le32 lo;
    __le16 hi_n_len;
 };

two members, one vibe. here's the whole thing laid out 💅

---

🎀 Members 🎀

• lo — the low [31:0] portion of the dma address of the TX buffer. and bestie, heads up: every even is unaligned on a 16 bit boundary — that's what the original says, word for word, so we're keeping it exactly like that, no cap 😭
• hi_n_len — a two-for-one icon 👑: bits 0-3 are the [35:32] portion of the dma address, and bits 4-15 are the length of the tx buffer. she's doing double duty and she's slaying

---

🦋 Description 🦋

literally what it says on the tin: this structure contains the dma address and the length of the transmission address. that's the whole assignment, and she ate 🔥
