ath5k_hw_set_txpower_limit(9)

💖 ath5k_hw_set_txpower_limit(9) 💖

okay bestie, welcome to the Kernel API Manual entry for ath5k_hw_set_txpower_limit — yes that's a mouthful, yes it's iconic, no you don't have to say it out loud.

---

✨ NAME ✨

ath5k_hw_set_txpower_limit — sets the txpower limit for the current channel 🦋

---

✨ SYNOPSIS ✨

int ath5k_hw_set_txpower_limit (struct ath5k_hw *ah , u8 txpower );

---

✨ ARGUMENTS ✨

• ah — the struct ath5k_hw, aka the whole hardware vibe right there 🫶
• txpower — the requested tx power limit, measured in 0.5dB steps (ngl, mind the steps, it's not plain dB)

---

✨ DESCRIPTION ✨

so here's the tea ☕ — this function gives the driver access to ath5k_hw_txpower for that specific case where a user or an application changes the txpower limit while the PHY is already running. like, mid-flight. main character energy fr fr 💅

that's literally the whole job and it ate. periodt.
