rsi_map_rates(9)

💅 rsi_map_rates — the Kernel API Manual, section 9, bestie ✨

Okay so picture this: you're deep in the RSI wireless driver (./drivers/net/wireless/rsi), and you've got a standard rate that needs to become a hw rate. That's literally the whole job of rsi_map_rates. It maps selected rates to hw rates. No cap, that's it, that's the function. 🎀

---

✨ SYNOPSIS ✨

bool rsi_map_rates (u16 rate , int *offset );

Like, two things go in, truthiness comes out. We love a tidy signature. 🫶

---

🌸 ARGUMENTS 🌸

• rate — the standard rate that you want mapped. That's the main character of this whole operation, ngl. 👑
• offset — the offset that will be returned. It's a pointer, so the function hands the value back through it. Iconic behaviour. 💫

---

🔥 RETURN 🔥

Returns 0 if it's an mcs rate, else 1. That's it. That's the vibe check. 🌈

Heads up bestie: those are the only two outcomes written here — 0 for mcs, 1 for anything else. Don't go reading extra meaning into it, fr fr. 💀
