In case of wireless interface retrieve the throughput by querying cfg80211. To perform this call a separate work must be scheduled because the function may sleep and this is not allowed within an RCU protected context (RCU in this case is used to iterate over all the neighbours). Use ethtool to retrieve information about an Ethernet link like HALF/FULL_DUPLEX and advertised bandwidth (e.g. 100/10Mbps). The metric is updated each time a new ELP packet is sent, this way it is possible to timely react to a metric variation which can imply (for example) a neighbour disconnection.

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 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.

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.

This option enables DAT (Distributed ARP Table), a DHT based

mesh networks. If you think that your network does not need

this option you can safely remove it and save some space.

|

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.

This is an option for use by developers; most people should

outputting debugging information to the kernel log. The

output is controlled via the module parameter debug.
