---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

depends on IWLWIFI

---help---
This option will enable sensitivity calibration for the iwlwifi
drivers.

---help---
This option will enable spectrum measurement for the iwlwifi drivers.

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.
