 * To use the debug system:

 * list here in the form of
 *
 * #define IWL_DL_xxxx VALUE
 *
 * where xxxx should be the name of the classification (for example, WEP).
 *
 * You then need to either add a IWL_xxxx_DEBUG() macro definition for your
 * classification, or use IWL_DEBUG(IWL_DL_xxxx, ...) whenever you want
 * to send output to that classification.
 *
 * The active debug levels can be accessed via files
 *
 *	/sys/module/iwlwifi/parameters/debug
 * when CONFIG_IWLWIFI_DEBUG=y.
 *
 *	/sys/kernel/debug/phy0/iwlwifi/debug/debug_level
