It makes OVS native tunneling honor tunnel-specified source addresses, in the same way that Linux kernel tunneling honors them. This patch made valid tun_src specified by flow-action can be used for tunnel_src of packet. add a "local" property for a route entry and enhance the priority of local route higher than user route. Like the kernel space when lookup the route, if there are tun_src specified by flow-action or port options. Check the tun_src wheather is a local address, then lookup the route.
