If you want to compile the driver as a module ( = code which can be
inserted in and removed from the running kernel whenever you want),
say M here and read <file:Documentation/kbuild/modules.txt>.
The module will be called ipw2100.ko.
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.

config ATH5K_DEBUG

---help---
Atheros 5xxx debugging messages.
Say Y, if and you will get debug options for ath5k.
To use this, you need to mount debugfs:
mkdir /debug/
mount -t debugfs debug /debug/
You will get access to files under:
/debug/ath5k/phy0/
To enable debug, pass the debug level to the debug module
parameter. For example:
modprobe ath5k debug=0x00000400
