The following commit has been merged in the merge/master branch: commit fa49b579c8daa6495c0fe200dfa9cd14cdf2dd46 Author: Sven Eckelmann sven@narfation.org Date: Sun Jul 15 22:26:51 2012 +0200

batman-adv: Split batadv_priv in sub-structures for features

The structure batadv_priv grows everytime a new feature is introduced. It gets hard to find the parts of the struct that belongs to a specific feature. This becomes even harder by the fact that not every feature uses a prefix in the member name.

The variables for bridge loop avoidence, gateway handling, translation table and visualization server are moved into separate structs that are included in the bat_priv main struct.
