The "bat_" prefix in the source files implementing the batman-adv sysfs and debugfs interface doesn't have a special meaning and are only used by these files and files that implement the actual B.A.T.M.A.N. path finding algorithm.

The prefix is better suited to mark files that are used to implement the main part of the path finding. All other files should not use it and therefore gets renamed.

The reserved fields in batman-adv packets are not set to a constant value. The content of these memory regions is leaked unintentionally to the network.

This regression was introduced in 3b27ffb00fbe9d9189715ea13ce8712e2f0cb0c5
