---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.
