If you are talking about OpenFlow 1.0, then the flow table cannot be
specified.  In OpenFlow 1.0, the arrangement of flow tables is meant to
explain the internal structure of the switch, and the switch is allowed
to place a flow in whichever flow table it believes best suits that
flow.

In OpenFlow 1.1, the situation is different.  I believe that it is
possible to place a flow in a specific table.  I don't know how to do
that with the reference switch; I would have to look it up there also.
