We make sure that the vlan port has the right backing interface in Linux when we add (ie. vconfig command is done before ovs-vsctl add-port). Likewise when we remove, we make sure that the vconfig is done after ovs-vsctl del-port is done.

Can you provide the simulation script, or a similar one that triggers
