  60 * To use the debug system;
  61 *
  62 * If you are defining a new debug classification, simply add it to the #define
  63 * list here in the form of:
  64 *
  65 * #define IPW_DL_xxxx VALUE
  66 *
  67 * shifting value to the left one bit from the previous entry.  xxxx should be
  68 * the name of the classification (for example, WEP)
  69 *
  70 * You then need to either add a IPW2100_xxxx_DEBUG() macro definition for your
  71 * classification, or use IPW_DEBUG(IPW_DL_xxxx, ...) whenever you want
  72 * to send output to that classification.
  73 *
  74 * To add your debug level to the list of levels seen when you perform
  75 *
  76 * % cat /proc/net/ipw2100/debug_level
  77 *
  78 * you simply need to add your entry to the ipw2100_debug_levels array.
  79 *
  80 * If you do not see debug_level in /proc/net/ipw2100 then you do not have
  81 * CONFIG_IPW2100_DEBUG defined in your kernel configuration
