Hello,
I am using the ovs-sandbox to run ovs-vswitchd in gdb and am having some
trouble adding ports to a bridge I've created. The port is added to the bridge,
however the link state is down and neither the bridge nor the added port appear
in the list of system interfaces. Therefore, it isn't able to process any
traffic.
