 108  * classification, or use IWL_DEBUG(IWL_DL_xxxx, ...) whenever you want
 109  * to send output to that classification.

 111  * To add your debug level to the list of levels seen when you perform
 112  *
 113  * % cat /proc/net/iwl/debug_level
 114  *
 115  * you simply need to add your entry to the iwl_debug_levels array.
 116  *
 117  * If you do not see debug_level in /proc/net/iwl then you do not have
 118  * CONFIG_IWLWIFI_DEBUG defined in your kernel configuration
