e.g. Set tunnel id for encapsulated VxLAN packet (out_key=flow):
ovs-vsctl add-port int-br vxlan0 -- set interface vxlan0 \
type=vxlan options:remote_ip=172.168.1.2 options:out_key=flow
ovs-ofctl add-flow int-br in_port=LOCAL, icmp,\
actions=set_tunnel:3, output:1 (1 is the port# of vxlan0)
Output tunnel ID should be modified to 3 with this patch.
