Merge tag 'batadv-next-for-davem-20160704' of git://git.open-mesh.org/linux-merge

Simon Wunderlich says:

====================
This feature patchset includes the following changes:

 - Cleanup work by Markus Pargmann and Sven Eckelmann (six patches)

 - Initial Netlink support by Matthias Schiffer (two patches)

 - Throughput Meter implementation by Antonio Quartulli, a kernel-space
   traffic generator to estimate link speeds. This feature is useful on
   low-end WiFi APs where running iperf or netperf from userspace
   gives wrong results due to heavy userspace/kernelspace overhead.
   (two patches)

 - API clean-up work by Antonio Quartulli (one patch)
