Staging: batman-adv: replace internal logging mechanism.

Browse Source 
batman-adv used its own logging infrastructure. Replace this with
standard kernel logging, printk(), with compile time and runtime
options to enable/disable different debug levels.

LOGGING/DEBUGGING
-----------------
All error messages, warnings and information messages are sent to the
kernel log. Depending on your operating system distribution this can be
read in one of a number of ways. Try using the commands: dmesg,
logread, or looking in the files /var/log/kern.log or
/var/log/syslog. All batman-adv messages are prefixed with
"batman-adv:" So to see just these messages try
dmesg | grep batman-adv
When investigating problems with your mesh network it is sometimes
necessary to see more detail debug messages. This must be enabled when
compiling the batman-adv module. When building batman-adv as part of
kernel, use "make menuconfig" and enable the option
"B.A.T.M.A.N. debugging". When compiling outside of the kernel tree it
is necessary to edit the file Makefile.kbuild and uncomment the line
#EXTRA_CFLAGS += -DCONFIG_BATMAN_DEBUG
The additional debug output is by default disabled. It can be enabled
either at kernel modules load time or during run time. To enable debug
output at module load time, add the module parameter debug=<value>.
<value> can take one of four values.
0 - All debug output disabled
1 - Enable messages related to routing / flooding / broadcasting
2 - Enable route or hna added / changed / deleted
3 - Enable all messages
e.g.
modprobe batman-adv debug=2
will load the module and enable debug messages for when routes or HNAs
change.
The debug output can also be changed at runtime using the file
/sys/module/batman-adv/parameters/debug. e.g.
echo 2 > /sys/module/batman-adv/parameters/debug
enables debug messages for when routes or HNAs
The debug output is sent to the kernel logs. So try dmesg, logread etc
to see the debug messages.
