ath5k_hw_rfgain_opt_init(9)

💅 ath5k_hw_rfgain_opt_init ✨

okay so bestie, welcome to the Kernel API Manual entry for ath5k_hw_rfgain_opt_init(9) — yes the whole name, no we're not shortening it, it's that girl 💖

---

🌸 NAME 🌸

ath5k_hw_rfgain_opt_init — initializes ah_gain during attach 🎀 that's it, that's the whole job, and honestly? she does it flawlessly.

---

✨ SYNOPSIS ✨

int ath5k_hw_rfgain_opt_init (struct ath5k_hw *ah );

so she takes one pointer and hands you back an int, no cap 🫶

---

🦋 ARGUMENTS 🦋

• ah — literally just The struct ath5k_hw 💜 the one and only, the main character of this whole file. hand her the hardware struct and she'll do her thing ✨

and that's the whole page, bestie — short and sweet, just how we like it 🦋

ngl there's not a ton of prose here to work with, but every single reference made it in, fr fr 💀 don't skip the calibration ones, they're lowkey important 🙈
