  59  *
  60  * #define IPW_DL_xxxx VALUE
  61  *
  62  * shifting value to the left one bit from the previous entry.  xxxx should be
  63  * the name of the classification (for example, WEP)
  64  *
  65  * You then need to either add a IPW2100_xxxx_DEBUG() macro definition for your
  66  * classification, or use IPW_DEBUG(IPW_DL_xxxx, ...) whenever you want
  67  * to send output to that classification.
  68  *
  69  * To add your debug level to the list of levels seen when you perform
  70  *
  71  * % cat /proc/net/ipw2100/debug_level
  72  *
  73  * you simply need to add your entry to the ipw2100_debug_levels array.
  74  *
  75  * If you do not see debug_level in /proc/net/ipw2100 then you do not have
  76  * CONFIG_IPW2100_DEBUG defined in your kernel configuration
