| help |
| 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. |

| config BATMAN_ADV_BATMAN_V |
| bool "B.A.T.M.A.N. V protocol" |
| depends on BATMAN_ADV && !(CFG80211=m && BATMAN_ADV=y) |
| 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 BATMAN_ADV_BLA |
| bool "Bridge Loop Avoidance" |
| depends on BATMAN_ADV && INET |
| select 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 BATMAN_ADV_DAT |
| bool "Distributed ARP Table" |
| depends on BATMAN_ADV && INET |
| 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 BATMAN_ADV_NC |
| bool "Network Coding" |
| depends on BATMAN_ADV |
| 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 BATMAN_ADV_MCAST |
| bool "Multicast optimisation" |
| depends on BATMAN_ADV && INET && !(BRIDGE=m && BATMAN_ADV=y) |
| default y |
| help |
| This option enables the multicast optimisation which aims to |
| reduce the air overhead while improving the reliability of |
| multicast messages. |
| |
| config BATMAN_ADV_DEBUGFS |
| bool "batman-adv debugfs entries" |
| depends on BATMAN_ADV |
| depends on 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 BATMAN_ADV_DEBUG |
| bool "B.A.T.M.A.N. debugging" |
| depends on BATMAN_ADV |
| 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 debugfs log or tracing |
| buffer. The output is controlled via the batadv netdev specific |
| log_level setting. |
| |
| config BATMAN_ADV_SYSFS |
| bool "batman-adv sysfs entries" |
| depends on BATMAN_ADV |
| default y |
| help |
| Say Y here if you want to enable batman-adv device configuration and |
| status interface through sysfs attributes. It is replaced by the |
| batadv generic netlink family but still used by various userspace |
| tools and scripts. |
| |
| If unsure, say Y. |
| |
| config BATMAN_ADV_TRACING |
| bool "B.A.T.M.A.N. tracing support" |
| depends on BATMAN_ADV |
| depends on EVENT_TRACING |
| help |
| This is an option for use by developers; most people should |
| say N here. Select this option to gather traces like the debug |
| messages using the generic tracing infrastructure of the kernel. |
| BATMAN_ADV_DEBUG must also be selected to get trace events for |
| batadv_dbg. |
