(better approach to mobile ad-hoc networking) is 13 a routing protocol for multi-hop ad-hoc mesh networks. The 14 networks may be wired or wireless. See 15 https://www.open-mesh.org/ for more information and user space 16 tools. 17 18config BATMAN_ADV_BATMAN_V 19 bool "B.A.T.M.A.N. V protocol (experimental)" 20 depends on BATMAN_ADV && !(CFG80211=m && BATMAN_ADV=y) 21 default n 22 help 23 This option enables the B.A.T.M.A.N. V protocol, the successor 24 of the currently used B.A.T.M.A.N. IV protocol. The main 25 changes include splitting of the OGM protocol into a neighbor 26 discovery protocol (Echo Location Protocol, ELP) and a new OGM 27 Protocol OGMv2 for flooding protocol information through the 28 network, as well as a throughput based metric. 29 B.A.T.M.A.N. V is currently considered experimental and not 30 compatible to B.A.T.M.A.N. IV networks. 31 32config BATMAN_ADV_BLA 33 bool "Bridge Loop Avoidance" 34 depends on BATMAN_ADV && INET 35 default y 36 help 37 This option enables BLA (Bridge Loop Avoidance), a mechanism 38 to avoid Ethernet frames looping when mesh nodes are connected 39 to both the same LAN and the same mesh. If you will never use 40 more than one mesh node in the same LAN, you can safely remove 41 this feature and save some space. 42 43config BATMAN_ADV_DAT 44 bool "Distributed ARP Table" 45 depends on BATMAN_ADV && INET 46 default n 47 help 48 This option enables DAT (Distributed ARP Table), a DHT based 49 mechanism that increases ARP reliability on sparse wireless 50 mesh networks. If you think that your network does not need 51 this option you can safely remove it and save some space. 52 53config BATMAN_ADV_NC 54 bool "Network Coding" 55 depends on BATMAN_ADV 56 default n 57 help 58 This option enables network coding, a mechanism that aims to 59 increase the overall network throughput by fusing multiple 60 packets in one transmission. 61 Note that interfaces controlled by batman-adv must be manually 62 configured to have promiscuous mode enabled in order to make 63 network coding work. 64 If you think that your network does not need this feature you 65 can safely disable it and save some space. 66 67config BATMAN_ADV_MCAST 68 bool "Multicast optimisation" 69 depends on BATMAN_ADV && INET && !(BRIDGE=m && BATMAN_ADV=y) 70 default n 71 help 72 This option enables the multicast optimisation which aims to 73 reduce the air overhead while improving the reliability of 74 multicast messages. 75 76config BATMAN_ADV_DEBUGFS 77 bool "batman-adv debugfs entries" 78 depends on BATMAN_ADV 79 depends on DEBUG_FS 80 default y 81 help 82 Enable this to export routing related debug tables via debugfs. 83 The information for each soft-interface and used hard-interface can be 84 found under batman_adv/ 85 86 If unsure, say Y. 87 88config BATMAN_ADV_DEBUG 89 bool "B.A.T.M.A.N. debugging" 90 depends on BATMAN_ADV_DEBUGFS 91 help 92 This is an option for use by developers; most people should 93 say N here. This enables compilation of support for 94 outputting debugging information to the kernel log. The 95 output is controlled via the module parameter debug. 96
