 * #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)

 * 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
