 56  * list here in the form of:
 57  *
 58  * #define IWL_DL_xxxx VALUE
 59  *
 60  * shifting value to the left one bit from the previous entry.  xxxx should be
 61  * the name of the classification (for example, WEP)
 62  *
 63  * You then need to either add a IWL_xxxx_DEBUG() macro definition for your
 64  * classification, or use IWL_DEBUG(IWL_DL_xxxx, ...) whenever you want
 65  * to send output to that classification.
 66  *
 67  * To add your debug level to the list of levels seen when you perform
 68  *
 69  * % cat /proc/net/iwl/debug_level
 70  *
 71  * you simply need to add your entry to the iwl3945_debug_levels array.
 72  *
 73  * If you do not see debug_level in /proc/net/iwl then you do not have
 74  * CONFIG_IWL3945_DEBUG defined in your kernel configuration
