Linux Wireless LAN Project 的目标是开发一个完整的

Linux WLAN
Driver debug statements

You can enable debugging in the driver by compiling with the 
-DWLAN_INCLUDE_DEBUG option.  This will add a considerable number 
of debug printks to the code.  To enable them by 'level' set the value 
of the wlan_debug module parameter to 0-5.

0 - nothing will print
1 - few, short messages
2 - more detailed behavior messages (this is what I use mostly)
3 - dump frame contents for each tx and rx frame
4 - function enter and exit messages
5 - I'm not sure if I've used this one anywhere.
