batctl: man: Add example section
A very simple example can help users to figure out how to get a very simple
mesh running. This allows to figure out the correct order of commands
directly from the manpage without needing additional (maybe currently
unreachable) resources from the internet.

+The setup of a batadv interface usually consists of creation of the the main
+interface, attaching of the (lower) hard-interface, adjusting of settings
+and bringup of the interface:
+# create batadv (mesh) interface bat0 with routing algorithm B.A.T.M.A.N. IV
+.RB "$" " batctl meshif bat0 interface create routing_algo
+# add the (already up and running) mesh0 interface as lower (hard) interface to bat0
+.RB "$" " batctl meshif bat0 interface -M add mesh0"
+# change some settings to better match the requirements of the user
+.RB "$" " batctl meshif bat0 orig_interval 5000"
+.RB "$" " batctl meshif bat0 distributed_arp_table disable"
+# set the batadv (mesh) interface up before it is possible to use it
+.RB "$" " ip link set up dev bat0"
+This only makes sure that the layer 2 functionality of bat0 is started up. It
+is the responsibility of the user to make sure that the bat0 device itself
+gets attached to a bridge, configured with an IP address (manually/DHCP client/...)
+or integrated in other parts of the system before it gets used.
+Also the attached (lower) hard-interfaces attached to the batadv interface must
+be configured by the user to support transportation of ethernet unicast and
+broadcast packets between its linked peers. The most common reason for a not
+working batman-adv mesh are incorrect configurations of the hard-interfaces,
+hardware, firmware or driver bugs which prevent that some of the packet types
+are correctly exchanged.
+The current status of interface can be checked using the debug tables. It is
+often relevant to check from which direct neighbors discovery packets were
+The next step is to check the (preferred) routes to originators. These will
+only be established when the metric has detected bidirectional connections
+between neighbors and might have forwarded discovery packets from not directly
+# get list of neighbors from which the current node was able to receive discovery
+.RB "$" " batctl meshif bat0 neighbors"
+# get (preferred) routes the routing algorithm found

+If the bat0 interface should no longer used by the system, it can be destroyed
