 * To use the debug system:

 * If you are defining a new debug classification, simply add it to the #define
 * list here in the form of
 *
 * #define IL_DL_xxxx VALUE
 *
 * where xxxx should be the name of the classification (for example, WEP).
 *
 * You then need to either add a IL_xxxx_DEBUG() macro definition for your
 * classification, or use IL_DEBUG(IL_DL_xxxx, ...) whenever you want
 * to send output to that classification.
 *
 * The active debug levels can be accessed via files
 *
 * 	/sys/module/iwl4965/parameters/debug{50}
 *	/sys/module/iwl3945/parameters/debug
 * 	/sys/class/net/wlan0/device/debug_level
