Commit e52c57bb1b30375e0bcc5523db76a672a4a8b4a4 renamed all
network ports to match the faceplate of the Gowin 1U Rack
Mount Server and added the br-lan bridge for the eth* ports.
This commit adds the PoE port to the br-lan bridge and a
br-wan bridge for the two SFP ports so that all ports are
part of the default network configuration.
