The sysfs files will be marked as deprecated in the near future. They are already replaced by the batadv generic netlink family. Add an Kconfig option to disable the sysfs support for users who want to test their tools or want to safe some space. This setting should currently still be enabled by default to keep backward compatible with legacy tools.
