The kernel components of linux-wlan currently have debugging code
that can be enabled via a "make config" option.  If debug output
has been compiled into a driver, enable it by setting the value of the 
module parameter xxx_debug
where xxx is the name of the component.  There are five levels of
debugging (1-5).  Here's a summary of the levels and their usage:
    1 - Enables most error messages for exception (but rare) conditions
    2 - Enables more exceptions  
    3 - Enables MAC status output
    4 - More status
    5 - Function entry and exit

The levels are additive.  For example, level 3 includes level 3
messages plus levels 1 and 2.

To configure p80211.o for debug output, put the following line (with
your own level number) in your modutils configuration file (usually
/etc/conf.modules or /etc/modules.conf):
 
  options p80211 wlan_debug=2

To configure the prism2_cs driver for debug output, put the following
line (with your own level number) in your /etc/pcmcia/config.opts
file:

  module "prism2_cs" opts "prism2_debug=2"

To configure the PCI, PLX, or USB driver for debug output, put the following
line (with your own level number) in your modutils configuration file (usually
/etc/conf.modules or /etc/modules.conf):

  options prism2_pci prism2_debug=3
  options prism2_plx prism2_debug=3
  options prism2_usb prism2_debug=3


Then configure the collection and display of your kernel output.  This
is usually done using syslog.  Here are the relevant entries from the
/etc/syslog.conf file on one of our test machines:

kern.*						/var/log/kernel
kern.*						/dev/tty9
*.info;mail.none;news.none;authpriv.none	/var/log/messages
*.info;mail.none;news.none;authpriv.none	/dev/tty10
