    Revert "Deprecate 'ovs_use_veth' and 'veth_mtu' options"
    
    The reason for reverting this is that when we tested this OVS
    port is show as DOWN and it can actually send traffic.
    
    An explanation is below:
    
    The DHCP port has "tap" in the name, but doesn't appear to be
    a tap device. It appears to be an OVS internal device. That device
    was then put into a different network namespace, which isn't
    visible to the root namespace in which ovs-vswitchd is running.
    Using internal devices in this manor is kind of a hack since
    ovs-vswitchd can't actually see the device, but it can still
    send and receive traffic on it.
    
    This reverts commit 850b4c025fa5652bfa474c78e7775d74fdb93df6.
