-config ATH9K
-	tristate "Atheros 802.11n wireless cards support"
-	depends on PCI && MAC80211 && WLAN_80211
-	---help---
-	  This module adds support for wireless adapters based on
-	  Atheros IEEE 802.11n AR5008 and AR9001 family of chipsets.
-
-	  If you choose to build a module, it'll be called ath9k.
