[ovs-dev] [PATCH] Fix userspace tunnel port with remote_ip is flow not work , where set vxlan port remote_ip is flow then the ovs-appctl tnl\ports\show ipv4 src is 0.0.0.0, tnl_port_map_lookup cann't find the tunnle port with a none zero outer src ip(as 192.168.1.10), so we should change the flow nw_src to zero and try again.

Can you post the exact tunnel flow you using? It looks like you have
skipped tunnel_src field. You need to specify it.
