[B.A.T.M.A.N.] [PATCH 2/2] batman-adv: Split README in kernel and external part

[Sven Eckelmann <sven@narfation.org>]

The README is shipped in a stripped down version as part of the kernel under
Documentation/networking/batman-adv.txt. The readme has to be manually merged
each time it gets prepared for submission to the networking subsystem
maintainer after the README was modified.

This extra work is reduced by splitting it in a README which contains the same
data as available in the kernel and README.external which contains the
information that only affect the external module.

 Batman advanced was implemented as a Linux kernel driver  to  re-

 network driver, and can be used on wifi as well as ethernet  lan,

+BATMAN-ADV external module
+--------------------------
+
+The  batman-adv  module  is  shipped  as part of the Linux kernel
+and as external module. The external  module   allows   to    get
+new    features without  upgrading  to  a  newer  kernel  version
+and to get batman-adv specific bugfixes  for  kernels  that   are
+not   supported   anymore.  It compiles  against  and should work
+with Linux 2.6.29 -   3.2.   Supporting  older  versions  is  not
+planned,  but it's probably easy to backport it. If you work on a
+backport, feel free to contact us.  :-)

+COMPILE
+-------
+
+To compile against your currently installed  kernel, just type:
+
+# make
+

+
+CONFIGURATION
+-------------
+
+The     in-kernel    module    can    be    configured    through
+menuconfig.   When  compiling outside  of the kernel,  tree it is
+necessary  to  configure  it  using    the   make  options.  Each
+option  can be set to to y (enabled), n (disabled) or m (build as
+module).  Available  options  and  their    possible   values are
+(default marked with an "*")
+
+ * CONFIG_BATMAN_ADV_DEBUG=[y|n*] (B.A.T.M.A.N. debugging)
+
+e.g., debugging can be enabled by
+
+# make CONFIG_BATMAN_ADV_DEBUG=y
+
+Keep  in  mind  that  all  options  must  also  be added to "make
+install" call.
