batman-adv: don't add loop detect macs to TT
The bridge loop avoidance (BLA) feature of batman-adv sends packets to probe for Mesh/LAN packet loops. Those packets are not sent by real clients and should therefore not be added to the translation table (TT). Signed-off-by: Simon Wunderlich <simon.wunderlich@open-mesh.com>
