---help---
This module adds support for wireless adapters based on
Atheros 5xxx chipset.
Currently the following chip versions are supported:
MAC: AR5211 AR5212
PHY: RF5111/2111 RF5112/2112 RF5413/2413
This driver uses the kernel's mac80211 subsystem.
If you choose to build a module, it'll be called ath5k. Say M if
unsure.
