====================
pull request for net-next: batman-adv 2016-08-16

This feature patchset is all about adding netlink support, which should
supersede our debugfs configuration interface in the long run. It is
especially necessary when batman-adv should be used in different
namespaces, since debugfs can not differentiate between those.

More specifically, the following changes are included:

 - Two fixes for namespace handling by Andrew Lunn, checking also the
   namespaces for parent interfaces, and supress debugfs entries
   for non-default netns

 - Implement various netlink commands for the new interface, by
   Matthias Schiffer, Andrew Lunn, Sven Eckelmann and Simon Wunderlich
   (13 patches):
    * routing algorithm list
    * hardif list
    * translation tables (local and global)
    * TTVN for the translation tables
    * originator and neighbor tables for B.A.T.M.A.N. IV
      and B.A.T.M.A.N. V
    * gateway dump functionality for B.A.T.M.A.N. IV
      and B.A.T.M.A.N. V
    * Bridge Loop Avoidance claims, and corresponding BLA group
    * Bridge Loop Avoidance backbone tables

 - Finally, mark batman-adv as netns compatible, by Andrew Lunn (1 patch)
