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. Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.

---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.

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.

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.
