I would start simple and build up. Don't use a bridge. Just put the IP
address 192.168.10.1 on the slave interface for port 2.
So something like:
ip link set eth0 up
ip addr add 192.168.10.1/24 dev lan2
ip link set lan2 up
then you can try ping 192.168.10.2.
Then trace the packet along the path. Does the ARP request make it to
192.168.10.2? Is a reply sent? ethtool -S lan2 will show you the
packet counts. Do the counters show the ARP going out and the reply
coming back?
