This was implemented in 2014.

    ofproto: Send port status message for port-mods, right away.
    
    Until now, when it processes OFPT_PORT_MOD message, Open vSwitch has waited
    for ports to notify it that their status has changed before it sends a
    port status update to controllers.
    
    Also, Open vSwitch never sent port config updates at all for port
    modifications other than OFPPC_PORT_DOWN.  I guess that this is a relic
    from the era when there was only one controller, since presumably the
    controller already knew that it changed the port configuration.  But in the
    multi-controller world, it makes sense to send such port status updates,
    and I couldn't quickly find anything in OF1.3 or OF1.4 that said they
    shouldn't be sent.
    
    EXT-338.
