701 * shifting value to the left one bit from the previous entry. xxxx should be
702 * the name of the classification (for example, WEP)
704 * You then need to either add a RTLLIB_xxxx_DEBUG() macro definition for your
705 * classification, or use RTLLIB_DEBUG(RTLLIB_DL_xxxx, ...) whenever you want

708 * To add your debug level to the list of levels seen when you perform
710 * % cat /proc/net/ipw/debug_level
712 * you simply need to add your entry to the ipw_debug_levels array.
