Aironet makes Arlan, a class of wireless LAN adapters. These use the chip, which is also used on several similar cards.
This driver is tested on the 655 and IC2200 series cards. Look at
<> for the latest information.

The driver is built as two modules, arlan and arlan-proc. The latter
is the /proc interface and is not needed most of time.

On some computers the card ends up in non-valid state after some
time. Use a ping-reset script to clear it.
