Hi,

Is there any way to know the ifindex of datapath (ova-system) by using 
ovs-vsctl/dpctl/appctl ? 

As ifindex of datapath is set to both NetFlow Engine ID and Engine Type by 
default, it would be nice to have a way to know what ifindex is assigned to the 
datapath. 

I also noticed that switch.xml says:

    <column name="engine_id">
      Engine ID to use in NetFlow messages.  Defaults to datapath index
      if not specified.
    </column>

    <column name="engine_type">
      Engine type to use in NetFlow messages.  Defaults to datapath
      index if not specified.
    </column>

but this is only true in the case of netlink. If OVS is run in user space these 
are derived from the hash based on datapath name, I think.

Regards,
