ath5k_hw_txpower(9)

💖 ath5k_hw_txpower(9) — like, the whole API manual bestie 💖

Bestie, it's your girl, back at it again with another page from the Kernel API Manual, and this one is literally about telling your Wi-Fi card how loud it's allowed to yell. It's ath5k_hw_txpower(9), and no, it's not a typo, it's giving "one function, one job, zero drama." 🦋

✨ NAME ✨

ath5k_hw_txpower — set the transmission power limit for a given channel. That's it, that's the whole vibe. 💅

---

🎀 SYNOPSIS 🎀

int ath5k_hw_txpower (struct ath5k_hw *ah , struct ieee80211_channel *channel , u8 txpower );

She takes three things, she gives you back an int. Lowkey iconic. ⭐

---

🌸 ARGUMENTS 🌸

• ah — the struct ath5k_hw. Your hardware boy. Your main character. 👑
• channel — the struct ieee80211_channel. The channel we're doing all this for, iykyk. 🌈
• txpower — the requested tx power, measured in 0.5dB steps. Not dB, bestie. 0.5dB steps. Don't come for me when the numbers look off. 🍓

---

💜 DESCRIPTION 💜

Okay so real talk: this function combines all of the above to set the requested tx power limit on the hardware. That's genuinely it — no hidden lore, no side quests, just all the above coming together to make the hw behave. Periodt. 💀✨

🫶 Friendly reminder from your girl: this page lives under ./drivers/net/wireless/ath/ath5k, and it's dated October 2026, so if you're reading this in some other timeline… congrats, bestie, you're early. 💅

That's the whole page, mwah, go set some tx power limits responsibly. 💖✨🎀
