Hi all, thank you so much for such an awesome project! I got a problem and need your help.

I've set up a 4-router wireless network, routers are connected together in a linear topology, by using the AP-APCLI (AP Client) mode provided by the driver. 

The figure shows how they are connected:

Ping status:

    Node 1 can ping 2, 3, 4.

    Node 2 can ping 1, 3.

    Node 3 can ping 1, 2, 4.

    Node 4 can ping 1, 3.

Use Node 2 to ping Node 4, the `tcpdump -i any icmp` output on Node 4:

    02:11:54.683342 bat0  P   IP 192.168.6.2 > 192.168.6.4: ICMP echo request, id 32006, seq 0, length 64

    02:11:54.693420 br-lan In  IP 192.168.6.2 > 192.168.6.4: ICMP echo request, id 32006, seq 0, length 64

    02:11:54.703673 br-lan Out IP 192.168.6.4 > 192.168.6.2: ICMP echo reply, id 32006, seq 0, length 64

    02:11:54.703677 ra0   Out IP 192.168.6.4 > 192.168.6.2: ICMP echo reply, id 32006, seq 0, length 64

Here I noticed that the outgoing interface is ra0, instead of bat0, maybe this is the problem?

Use Node 4 to ping Node 2, Node 2 gets nothing. 

`batctl ping` works well:

Node 2 -> 4:

    ~# ./batctl ping 192.168.6.4

    PING 192.168.6.4 (9a:15:64:00:0b:f7) 20(48) bytes of data

    20 bytes from 192.168.6.4 icmp_seq=1 ttl=49 time=1.20 ms

Node 4 -> 2:

    ~# ./batctl ping 192.168.6.2

    PING 192.168.6.2 (9a:15:64:00:0b:f8) 20(48) bytes of data

    20 bytes from 192.168.6.2 icmp_seq=1 ttl=49 time=1.08 ms

`batctl o` outputs below. I also feel the output on node 3 and 4 are a bit weird, too.
