[IWLWIFI]: add iwlwifi wireless drivers

Browse Source 
This patch adds the mac80211 based wireless drivers for the Intel
PRO/Wireless 3945ABG/BG Network Connection and Intel Wireless WiFi
Link AGN (4965) adapters.

select FW_LOADER
default n
---help---
Select to enable drivers based on the iwlwifi project. This
project provides a common foundation for Intel's wireless
drivers designed to use the mac80211 subsystem.
See <file:Documentation/networking/README.iwlwifi> for
information on the capabilities currently enabled in this
driver and for tips for debugging issues and problems.
config IWLWIFI_DEBUG
bool "Enable full debugging output in iwlwifi drivers"
depends on IWLWIFI
default y
---help---
This option will enable debug tracing output for the iwlwifi
drivers.
This will result in the kernel module being ~100k larger. You can
control which debug output is sent to the kernel log by setting the
value in
/sys/bus/pci/drivers/${DRIVER}/debug_level
This entry will only exist if this option is enabled.
To set a value, simply echo an 8-byte hex value to the same file:
% echo 0x43fff > /sys/bus/pci/drivers/${DRIVER}/debug_level
You can find the list of debug mask values in:
drivers/net/wireless/mac80211/iwlwifi/iwl-debug.h
If this is your first time using this driver, you should say Y here
as the debug information can assist others in helping you resolve
any problems you may encounter.
config IWLWIFI_SENSITIVITY

This option will enable sensitivity calibration for the iwlwifi
drivers.

This option will enable spectrum measurement for the iwlwifi drivers.

Intel Wireless WiFi Link 4965AGN
This driver uses the kernel's mac80211 subsystem.
See <file:Documentation/networking/README.iwlwifi> for
information on the capabilities currently enabled in this
driver and for tips for debugging any issues or problems.
In order to use this driver, you will need a microcode (uCode)
image for it. You can obtain the microcode from:
<http://intellinuxwireless.org/>.
See the above referenced README.iwlwifi for information on where
to install the microcode images.
If you want to compile the driver as a module ( = code which can be
inserted in and remvoed from the running kernel whenever you want),
say M here and read <file:Documentation/modules.txt>. The module
will be called iwl4965.ko.
