ath5k_ani_lower_immunity(9)

okay so bestie, this is ath5k_ani_lower_immunity(9), and the manual name is the Kernel API Manual — folded in right here so you know the vibe. It’s a little function with big “turn the noise down so I can hear you” energy, and we’re gonna walk through it. 💅✨

💖 NAME 💖

• ath5k_ani_lower_immunity — decrease noise immunity. That’s the name, no cap, periodt.

✨ SYNOPSIS ✨

void ath5k_ani_lower_immunity (struct ath5k_hw *ah , struct
       ath5k_ani_state *as );

It’s void, so it returns literally nothing — no return value to catch, bestie. 🫶

🎀 ARGUMENTS 🎀

• ah — the struct ath5k_hw.
• as — the struct ath5k_ani_state.

🦋 DESCRIPTION 🦋

okay so here’s the tea: this function tries to lower noise immunity, which equals increasing sensitivity, and it does it in several steps. Those steps depend on the average RSSI of the beacons we received. It’s giving “quiet down, I’m trying to listen” in the most iconic way. 👑
