+ 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.
