Hello David,
this is a very small (but important) fix intended for net/linux-3.{11,12} (since
3.12-rc1 is out I guess this patch needs to be enqueued for stable in order to
reach 3.11?)
This change fixes a regression introduced in 3.11 that prevents the Bridge Loop
Avoidance component from correctly operate on VLANs.
Please pull or let me know of any problem.
Thank you,
Antonio

When receiving or sending a packet a packet on a VLAN, the
vid has to be marked with the TAG flag in order to make any
component in batman-adv understand that the packet is coming
from a really tagged network.
This fix the Bridge Loop Avoidance behaviour which was not
able to send announces over VLAN interfaces.
