💅 ar9003_hw_s...gate_mrc_cck(9) 💅

okay so bestie, welcome to the Kernel API Manual — yes that's the manual name, yes it's fancy, and yes this page is about one very specific little function. buckle up 🎀

---

✨ NAME ✨

ar9003_hw_spur_mitigate_mrc_cck — literally converts baseband spur frequency. that's the whole gig. that's what she does. 💖

---

🌸 SYNOPSIS 🌸

void ar9003_hw_spur_mitigate_mrc_cck (struct ath_hw *ah , struct
       ath9k_channel *chan );

note the spacing in that second line — that's exactly how it's printed, and we do not touch it. periodt. ✨

---

🦋 ARGUMENTS 🦋

• ah — the atheros hardware structure. that's your hardware bestie, the struct that holds everything about the chip. 🫶
• chan — okay so the manpage literally gives us nothing here. no description. zero. nada. 🙈 we're keeping it exactly that way because that's what the original says. (iykyk)

---

💜 DESCRIPTION 💜

so this one's for single-chip solutions — key detail, don't forget it. she converts to baseband spur frequency given the input channel frequency, and then computes register settings below. that's the flow, bestie: input channel frequency in → baseband spur frequency out → register settings computed. 🔥

and the vibe? Spur mitigation for MRC CCK. that's what this function is bringing to the table. iconic.

• Kernel file ./drivers/net/wireless/ath/ath9k/ar9003_phy.c — go read the source, it's all there, no cap 📂
• ar9003_hw_set_channel(9) — the sibling function, run don't walk 🏃‍♀️

💀 quick reminder: keep both of those references intact when you're passing this around. they're part of the page, not decoration. 🎀

and that's the whole page, bestie!! 🌈 this was brought to you by ./drivers/net/wireless/ath/ath9k, dated October 2026, and yes — the manpage title at the bottom is the same little ar9003_hw_s...gate_mrc_cck(9) we started with. full circle, main character energy, slay. 💅✨🌸🦋💖
