The following commit has been merged in the master branch: commit 94d1dd87316fdb7a403a2750e13ec839fd2fadea Author: Antonio Quartulli antonio@open-mesh.com Date: Mon Mar 31 13:48:10 2014 +0200

batman-adv: change the MAC of each VLAN upon ndo_set_mac_address

The MAC address of the soft-interface is used to initialise the "non-purge" TT entry of each existing VLAN. Therefore when the user invokes ndo_set_mac_address() all the "non-purge" TT entries have to be updated, not only the one belonging to the non-tagged network.
