Revert "ex400: enable network by default"
This reverts commit 0cd508d8.
It turns out that not starting network by default had a reason. See fccb9d5e (Prevent ethernet to start up by default., 2017-05-11).
Quoting the commit message:
This is needed as the setup has all port in the same switch so WAN is connected to LAN and dhcp on clients on LAN is getting out to the ISP and stealing ip numbers.
We do not want to have networking by default with a static IP on the WAN-port. In addition, test-scripts would need adaptation if the networking is not to started by default, which is not worth it for an old platform like this.
