batman-adv: Sync config options with kernel Kconfig

The kernel already provides all available kernel options for batman-adv and
even includes more verbose descriptions of each option. Importing this
Kconfig (with minor adjustments) file as Config.in allows to share most
information between kernel and OpenWrt.

 config KMOD_BATMAN_ADV_BATMAN_V
-       bool "enable batman v routing algorithm"
+       bool "B.A.T.M.A.N. V protocol"
        depends on PACKAGE_kmod-batman-adv
        default y
+       help
+         This option enables the B.A.T.M.A.N. V protocol, the successor
+         of the currently used B.A.T.M.A.N. IV protocol. The main
+         changes include splitting of the OGM protocol into a neighbor
+         discovery protocol (Echo Location Protocol, ELP) and a new OGM
+         Protocol OGMv2 for flooding protocol information through the
+         network, as well as a throughput based metric.
+         B.A.T.M.A.N. V is currently considered experimental and not
+         compatible to B.A.T.M.A.N. IV networks.
 
 config KMOD_BATMAN_ADV_BLA
-       bool "enable bridge loop avoidance"
+       bool "Bridge Loop Avoidance"
        depends on PACKAGE_kmod-batman-adv
+       select PACKAGE_kmod-lib-crc16
        default y
+       help
+         This option enables BLA (Bridge Loop Avoidance), a mechanism
+         to avoid Ethernet frames looping when mesh nodes are connected
+         to both the same LAN and the same mesh. If you will never use
+         more than one mesh node in the same LAN, you can safely remove
+         this feature and save some space.
 
 config KMOD_BATMAN_ADV_DAT
-       bool "enable distributed arp table"
+       bool "Distributed ARP Table"
        depends on PACKAGE_kmod-batman-adv
        default y
+       help
+         This option enables DAT (Distributed ARP Table), a DHT based
+         mechanism that increases ARP reliability on sparse wireless
+         mesh networks. If you think that your network does not need
+         this option you can safely remove it and save some space.
 
 config KMOD_BATMAN_ADV_NC
-       bool "enable network coding [requires promisc mode support]"
+       bool "Network Coding"
        depends on PACKAGE_kmod-batman-adv
-       default n
+       help
+         This option enables network coding, a mechanism that aims to
+         increase the overall network throughput by fusing multiple
+         packets in one transmission.
+         Note that interfaces controlled by batman-adv must be manually
+         configured to have promiscuous mode enabled in order to make
+         network coding work.
+         If you think that your network does not need this feature you
+         can safely disable it and save some space.
 
 config KMOD_BATMAN_ADV_MCAST
-       bool "enable multicast transmission optimization"
+       bool "Multicast optimisation"
        depends on PACKAGE_kmod-batman-adv
+       help
+         This option enables the multicast optimisation which aims to
+         reduce the air overhead while improving the reliability of
+         multicast messages.
 
 config KMOD_BATMAN_ADV_DEBUGFS
-       bool "enable debugfs support"
+       bool "batman-adv debugfs entries"
        depends on PACKAGE_kmod-batman-adv
-       default n
+       select KERNEL_DEBUG_FS
+       help
+         Enable this to export routing related debug tables via debugfs.
+         The information for each soft-interface and used hard-interface can be
+         found under batman_adv/
+
+         If unsure, say N.
 
 config KMOD_BATMAN_ADV_DEBUG_LOG
-       bool "enable verbose debug logging"
-       depends on PACKAGE_kmod-batman-adv

        depends on KMOD_BATMAN_ADV_DEBUGFS
-       default n
+       help
+         This is an option for use by developers; most people should
+         say N here. This enables compilation of support for
+         outputting debugging information to the kernel log. The
+         output is controlled via the module parameter debug.

-B.A.T.M.A.N. advanced is a kernel module which allows to
-build layer 2 mesh networks. This package builds
-version $(PKG_VERSION) of the kernel module.
+B.A.T.M.A.N. (better approach to mobile ad-hoc networking) is
+a routing protocol for multi-hop ad-hoc mesh networks. The
+networks may be wired or wireless. See
+https://www.open-mesh.org/ for more information and user space
+tools. This package builds version $(PKG_VERSION) of the kernel
