====================
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)
