726 * list here in the form of:
728 * #define RTLLIB_DL_xxxx VALUE
730 * shifting value to the left one bit from the previous entry. xxxx should be
731 * the name of the classification (for example, WEP)
733 * You then need to either add a RTLLIB_xxxx_DEBUG() macro definition for your
734 * classification, or use RTLLIB_DEBUG(RTLLIB_DL_xxxx, ...) whenever you want
735 * to send output to that classification.
737 * To add your debug level to the list of levels seen when you perform
739 * % cat /proc/net/ipw/debug_level
741 * you simply need to add your entry to the ipw_debug_levels array.
