OpenFlow protocol doesn't support such. You need to use OVS specific
protocol (OVS JSON DB). Ryu has handy libries for that:
ryu/lib/ovs/
Q1) Is it way of creating virtual port??
# ovs-vsctl add-port br0 vi0 -- set Interface vi0 type=internal
You mean I can create virtual port with ryu/lib/ovs/vsctl.py,
Is it right?

I don't know what 'add the code to openvswitch' means. But if you use
tunneling protocols that OVS supports (e.g. GRE), then what you need
to do is creating a virtual tunneling port. Then you can use OpenFlow
tunnel_id action and match via Ryu.
Q2) I would like to support GTP in openvswitch and manage it via Ryu.
Could you explain more tunnel_id action and match via Ryu?
Thanks.
