STRUCT BRCMU_D11INF(9)

💅 struct brcmu_d11inf(9)

okay so bestie, welcome to the Kernel API Manual page for struct brcmu_d11inf — it's giving "tiny struct, big job" energy ngl ✨

---

🌸 NAME

struct brcmu_d11inf — this little icon literally provides functions that translate channel format 🦋

---

🎀 SYNOPSIS

struct brcmu_d11inf {
    u8 io_type;
    void (*encchspec)(struct brcmu_chan *ch);
    void (*decchspec)(struct brcmu_chan *ch);
 };

like, that's the whole thing. three fields. she's compact and she knows it 💅

---

✨ Members

• io_type — decides which version of the channel format the firmware is out here using 👑
• encchspec — encodes channel info into a chanspec; it requires the center channel number and straight-up ignores the control one 🙈 (yes fr, it does not care about the control channel at all)
• decchspec — decodes a chanspec back into generic info 🔥 the reverse trip, the glow-down if you will

---

🫶 SEE ALSO

• Kernel file ./drivers/net/wireless/broadcom/brcm80211/include/brcmu_d11.h
• struct brcmu_chan(9)

go read those, iykyk 💖

lowkey a tiny reminder bestie: encchspec wants the center channel number and does not want the control one — don't come for me, that's just what the page says 😭

---

and that's the whole vibe check! 🌈 source lives at ./drivers/net/wireless/broadco..., dated October 2026, and the page is struct brcmu_d11inf(9) — slay, go translate some channel formats, mwah 🎀💜
