By connecting multiple batman-adv mesh nodes to the same LAN network an ethernet loop can be created when the soft-interface is bridged with the LAN interface. A simple visualization of the loop:

node1 <-- LAN --> node2 | | wifi <-- mesh --> wifi

This patch adds the functionality to detect other batman-adv nodes connected to the LAN and select a 'gateway' to talk to the non-batman-adv devices on this LAN. All traffic from and to the mesh will be handled by this gateway to avoid the loop. OGMs received via the soft-interface are interpreted as 'port announcements' to locate potential batman-adv nodes. The patch can also deal with vlans on top of batX and offers a list of LAN neighbors via debugfs.
