 * 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 IPW_DL_xxxx VALUE
 *
 * shifting value to the left one bit from the previous entry.  xxxx should be
 * the name of the classification (for example, WEP)
 *
 * You then need to either add a IPW2100_xxxx_DEBUG() macro definition for your
 * classification, or use IPW_DEBUG(IPW_DL_xxxx, ...) whenever you want
 * to send output to that classification.
 *
 * To add your debug level to the list of levels seen when you perform
 *
 * % cat /proc/net/ipw2100/debug_level
 *
 * you simply need to add your entry to the ipw2100_debug_levels array.
 *
 * If you do not see debug_level in /proc/net/ipw2100 then you do not have
 * CONFIG_IPW2100_DEBUG defined in your kernel configuration
