commit 59221041095c2b83205caab3dbabc94d7a6f32f9 Author: Antonio Quartulli antonio@open-mesh.com Date: Wed Sep 11 19:14:44 2013 +0200

batman-adv: set the TAG flag for the vid passed to BLA

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.

Introduced by 0b1da1765fdb00ca5d53bc95c9abc70dfc9aae5b ("batman-adv: change VID semantic in the BLA code")
