A driver for the Intel PRO/Wireless 2200BG and 2915ABG Network
Connection adapters.

See Documentation/networking/README.ipw2200 for
information on the capabilities currently enabled in this
driver and for tips for debugging issues and problems.

In order to use this driver, you will need a firmware image for it.
You can obtain the firmware from
<http://ipw2200.sf.net/>. See the above referenced README.ipw2200
for information on where to install the firmware images.

You will also very likely need the Wireless Tools in order to
configure your card:

It is recommended that you compile this driver as a module (M)
rather than built-in (Y). This driver requires firmware at device
initialization time, and when built-in this typically happens
before the filesystem is accessible (hence firmware will be
unavailable and initialization will fail). If you do choose to build
this driver into your kernel image, you can avoid this problem by
including the firmware and a firmware loader in an initramfs.
