552 * shifting value to the left one bit from the previous entry. xxxx should be
553 * the name of the classification (for example, WEP)

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