commit f13f960797fd1969b3c0470cc97435ddfb6aecb4 Author: Simon Wunderlich simon@open-mesh.com Date: Thu Nov 21 11:52:16 2013 +0100

batman-adv: add debugfs support to view multiif tables

Show tables for the multi interface operation. Originator tables are added per hard interface.

This patch also changes the API by adding the interface to the bat_orig_print() parameters.
