💖 ARGUMENTS 💖

• ah — bestie this is the struct ath5k_hw, the hardware handle, the main character of the whole situation 👑
• channel — and this one's the struct ieee80211_channel, the channel struct, the vibe check of a channel if u will 🌈

⭐ DESCRIPTION ⭐

So what it actually does: it brings up the MAC + PHY Chips and programs the PLL ✨ that's it, that's the job, and honestly? iconic. 🧚
