This seems reasonable.

It would be a good idea to add a note to the commit message that this is
only useful for upgrades from 1.9, since that's the only version that
has ofport_request but does not have the newer behavior of ofport.

We should add an --if-exists option to "ovs-vsctl set", so that a long
string of "ovs-vsctl -- --if-exists set interface <foo> ..." commands
does not fail if one of the interfaces happens to have disappeared
(e.g. its VM was shut down).  I'm working on that.
