Yes, looks like I've missed this while reviewing your tp_meter code. Was
the crash something like:

    root@node02:~# /host/batctl/batctl  tp 02:ba:de:af:ff:01
    Throughput meter called towards 02:ba:de:af:ff:01
    tp_meter.c:198:36: runtime error: division by zero
    traps: batctl[246] trap divide error ip:410f31 sp:7ffea78512c0 error:0 in batctl[400000+18000]
    Floating point exception

I will most likely add code catching it in both batctl and batman-adv.

Kind regards,
	Sven
