Ok, I wonder how I can filter out those secondary interface MAC addresses
of 1-hop neighbors.
Can those addresses be recognized by comparing it to the Nexthop column?
This seems to be the major problem for me right now.

Are those the MAC-addresses of the bridge interface. Say, when I bridge bat0 into
br-lan, then the MAC of br-lan will show up as client?
