In this configuration you're supposed to put an IP address on the fec2
interface (eth1), not on br1.
br1 will handle offloaded forwarding between port5 and the external
ports (port3, port4). It doesn't need an IP address. In fact, if you
give it an IP address, you will make the sent packets go through the br1
interface, which does dev_queue_xmit() to the bridge ports (port3, port4,
port5), ports which are DSA, so they do dev_queue_xmit() through their
DSA master - eth0. So the system behaves as instructed.
