 * 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 IEEE80211_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 IEEE80211_xxxx_DEBUG() macro definition for your
 * classification, or use IEEE80211_DEBUG(IEEE80211_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/ipw/debug_level
 * you simply need to add your entry to the ipw_debug_levels array.
 * If you do not see debug_level in /proc/net/ipw then you do not have
 * CONFIG_IEEE80211_DEBUG defined in your kernel configuration
