142 * shifting value to the left one bit from the previous entry. xxxx should be
143 * the name of the classification (for example, WEP)
145 * You then need to either add a IEEE80211_xxxx_DEBUG() macro definition for your
146 * classification, or use IEEE80211_DEBUG(IEEE80211_DL_xxxx, ...) whenever you want
147 * to send output to that classification.
149 * To add your debug level to the list of levels seen when you perform
151 * % cat /proc/net/ieee80211/debug_level
153 * you simply need to add your entry to the ieee80211_debug_level array.
155 * If you do not see debug_level in /proc/net/ieee80211 then you do not have
