└─>Enable full debugging output in the iwlwifi driver
In linux kernel since version 2.6.24 (release Date: 2008-01-24)  
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/module/iwlwifi/parameters/debug

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/module/iwlwifi/parameters/debug

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.
