129 * list here in the form of
131 * #define IWL_DL_xxxx VALUE
133 * where xxxx should be the name of the classification (for example, WEP).
135 * You then need to either add a IWL_xxxx_DEBUG() macro definition for your

137 * to send output to that classification.

141 * /sys/module/iwlagn/parameters/debug{50}
142 * /sys/class/net/wlan0/device/debug_level
144 * when CONFIG_IWLWIFI_DEBUG=y.
