2016-07-04batman-adv: split routing API data structure in subobjectsAntonio Quartulli
The routing API data structure contains several function pointers that can easily be grouped together based on the component they work with. Split the API in subobjects in order to improve definition readability. At the same time, remove the "bat_" prefix from the API object and its fields names. These are batman-adv private structs and there is no need to always prepend such prefix, which only makes function invocations much much longer.

2016-07-04batman-adv: throughput meter implementationAntonio Quartulli
The throughput meter module is a simple, kernel-space replacement for throughtput measurements tool like iperf and netperf. It is intended to approximate TCP behaviour. It is invoked through batctl: the protocol is connection oriented, with cumulative acknowledgment and a dynamic-size sliding window. The test *can* be interrupted by batctl. A receiver side timeout avoids unlimited waitings for sender packets: after one second of inactivity, the receiver abort the ongoing test.

2016-07-04batman-adv: add netlink command to query generic mesh information filesMatthias Schiffer
BATADV_CMD_GET_MESH_INFO is used to query basic information about a batman-adv softif (name, index and MAC address for both the softif and the primary hardif; routing algorithm; batman-adv version).

2016-07-04batman-adv: add generic netlink family for batman-advMatthias Schiffer
debugfs is currently severely broken virtually everywhere in the kernel where files are dynamically added and removed (see http://lkml.iu.edu/hypermail/linux/kernel/1506.1/02196.html for some details). In addition to that, debugfs is not namespace-aware. Instead of adding new debugfs entries, the whole infrastructure should be moved to netlink. This will fix the long standing problem of large buffers for debug tables and hard to parse text files.
