Running tcpdump on the device i'm trying to ping, there are ARP
requests and replies. But the replies are never received by the
target, arp -a shows <incomplete>.
Looking at the stats counters in debugfs, the packets are counted in
in_unicast, but also sw_in_filtered.
Port 0 is lan0 and port 5 is the cpu port.
