Simon Wunderlich says:

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

 - two patches with minimal clean up work by Antonio Quartulli and
   Simon Wunderlich

 - eight patches of B.A.T.M.A.N. V, API and documentation clean
   up work, by Antonio Quartulli and Marek Lindner

 - Andrew Lunn fixed the skb priority adoption when forwarding
   fragmented packets (two patches)

 - Multicast optimization support is now enabled for bridges which
   comes with some protocol updates, by Linus Luessing
