Reinette Chatre 81963d6857 iwlwifi: cleanup spectrum measurement command support
In iwlagn the support for spectrum measurement command has been
disabled since v2.6.29 without any requests for it. In addition to this
when this command is indeed enabled it has been found to trigger firmware
SYSASSERT on at least 4965 and 5100 hardware (see
http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=1952 ). Since then
this code has been bitrotting and cannot just be enabled without porting.

Remove support for spectrum measurement command from iwlagn. It can be
added back if there is a future need and the firmware problem it triggers
has been fixed. Support for the spectrim measurement notification remains
as it has been enabled all the time.

In addition to this remove the 3945 spectrum measurement command Kconfig
option and make this command always supported. The code added by this
enabling is minimal and only run when user triggers a spectrum measurement
request via sysfs.

config IWLWIFI_DEBUG
bool "Enable full debugging output in iwlagn and iwl3945 drivers"
depends on IWLWIFI
---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/class/net/wlan0/device/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/class/net/wlan0/device/debug_level
You can find the list of debug mask values in:
drivers/net/wireless/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.

Enable creation of debugfs files for the iwlwifi drivers.
config IWLWIFI_DEVICE_TRACING
bool "iwlwifi device access tracing"
depends on IWLWIFI
depends on EVENT_TRACING
help
Say Y here to trace all commands, including TX frames and IO
accesses, sent to the device. If you say yes, iwlwifi will
register with the ftrace framework for event tracing and dump
all this information to the ringbuffer, you may need to
increase the ringbuffer size. See the ftrace documentation
for more information.
When tracing is not enabled, this option still has some
(though rather small) overhead.
If unsure, say Y so we can help you better when problems
occur.
config IWLAGN

depends on IWLWIFI
---help---
Select to build the driver supporting the:
Intel Wireless WiFi Link Next-Gen AGN
This driver uses the kernel's mac80211 subsystem.
In order to use this driver, you will need a microcode (uCode)
image for it. You can obtain the microcode from:
<http://intellinuxwireless.org/>.
The microcode is typically installed in /lib/firmware. You can
look in the hotplug script /etc/hotplug/firmware.agent to
determine which directory FIRMWARE_DIR is set to when the script
runs.
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 iwlagn.
