----------------------------------------------------------------------- tag batman-adv-for-davem

With this patchset we finally introduce our new routing protocol: B.A.T.M.A.N. V. Its implementation started quite some years ago, but due to the big changes being introduced it took a while to be discussed, designed, worked, re-worked, tested and debugged (well, we're never done with the latest). The entire operation has basically been a team work involving all the core contributors together with other people interested in the project.

The new protocol is divided into two main subcomponents, called respectively ELP and OGMv2. The former is in charge of dealing with the neighbour discovery and link quality estimation, while the latter implements the algorithm that spreads the metrics around the network and computes optimal paths.

The biggest change introduced with B.A.T.M.A.N. V is the new metric: the protocol won't rely on packet loss anymore, but it will use the estimated throughput extracted directly from the wifi driver (when available) by querying cfg80211. Batman-adv will also send some unicast probing packets when an interface is not used for payload traffic to make sure that such values are current.

The new protocol can be compiled-in or not like other features we have and when selected will pull in CFG80211 as dependency for the reason described above.

Thanks to the big work brought up in the past by Marek Lindner, batman-adv can easily deal several protocol implementations, therefore compiling in this new version does not exclude the older. This means that the user is offered the option to choose the protocol when creating the mesh interface (default is the old one to keep backward compatibility).

Along with the protocol there are some sysfs knobs that are introduced to fine tune some of its behaviours, but users are recommended to keep the default values unless they know what they are doing.

The last patch is about advertising our own patchwork platform (thanks to Sven Eckelmann for having set that up!) in the MAINTAINERS file.
