config PCMCIA_RAYCS
tristate "Aviator/Raytheon 2.4GHz wireless support"
When built as module you get the module prism54
-config USB_ZD1201
- tristate "USB ZD1201 based Wireless device support"
- depends on CFG80211 && USB
- select WIRELESS_EXT
- select WEXT_PRIV
- select FW_LOADER
- ---help---
- Say Y if you want to use wireless LAN adapters based on the ZyDAS
- ZD1201 chip.
-
- This driver makes the adapter appear as a normal Ethernet interface,
- typically on wlan0.
-
- The zd1201 device requires external firmware to be loaded.
- This can be found at http://linux-lc100020.sourceforge.net/
-
- To compile this driver as a module, choose M here: the
- module will be called zd1201.

+ Say Y if you want to use wireless LAN adapters based on the ZyDAS
+ ZD1201 chip.
+
+ This driver makes the adapter appear as a normal Ethernet interface,
+ typically on wlan0.
+
+ The zd1201 device requires external firmware to be loaded.
+ This can be found at http://linux-lc100020.sourceforge.net/
+
+ To compile this driver as a module, choose M here: the
+ module will be called zd1201.
