85cf8c859d batman-adv: netlink: add originator and neighbor table queries
Add BATADV_CMD_GET_ORIGINATORS and BATADV_CMD_GET_NEIGHBORS commands,
using handlers bat_orig_dump and bat_neigh_dump in batadv_algo_ops. Will
always return -EOPNOTSUPP for now, as no implementations exist yet.

f32ed4b54e batman-adv: Provide TTVN in the mesh_info netlink msg
The TTVN is the main information for the debugging of translation table
problems. It is therefore necessary when comparing the global translation
tables.

d34f05507d batman-adv: netlink: add translation table query
This adds the commands BATADV_CMD_GET_TRANSTABLE_LOCAL and
BATADV_CMD_GET_TRANSTABLE_GLOBAL, which correspond to the transtable_local
and transtable_global debugfs files.

The batadv_tt_client_flags enum is moved to the UAPI to expose it as part
of the netlink API.

29824a55c0 batman-adv: split routing API data structure in subobjects
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.

33a3bb4a33 batman-adv: throughput meter implementation
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.

Based on a prototype from Edo Monticelli <montik@autistici.org>

5da0aef5e9 batman-adv: add netlink command to query generic mesh information files
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).

09748a22f4 batman-adv: add generic netlink family for batman-adv
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.
