Thanks Ben for your info.
I think I am finally catching a bit with the concept of 'clone' action
after reviewing below patches in order, so the for OVN case, the new
'clone' action aims to drop most of the OVS patch port, and after add new
ct_clear action, some fixes, I assume it works with NAT, and I am using
2.8.1 for testing, please point out the patches if I am missing any. One
other question is Can I set bridge-mapping:physnet1:br-int? In other words,
the br-int has vm vif, has tunnel ports(the tunnel ports would point to
another nic), and has the external nic as local gateway router port, is it
feasible without configuring more extra flows.

ovn-controller: Drop most uses of OVS patch ports.
[ovs-dev] [PATCH 2/3] dpif-netdev: Add clone action

[ovs-dev] ovn ping from VM to external gateway IP failed.
