Ryu does not use L3 info to transmit a packet. Ryu makes a flow table
by a port number and MAC address (and tunnel id).
Ryu transmit a packet to only the port of the same tenant, because Ryu
knows the tenant (exactly a network of quantum/neutron) which an
interface connected to each port of each switch belongs to.
