SNAT Traffic from Non-Fip VM of non-primary DPN to FIP of non-primary DPN is dropping

Issue : SNAT Traffic from Non-Fip VM of non-primary DPN to FIP of non-primary DPN is dropping with SNAT flows on different DPN.

As per attached topology, when an Non-FIP(VM-131) try to reaches FIP(VM-211), the packet is forwarded to the DPN1->DPN2 and DPN2(Primary-NAPT) has the SNAT flows. After going though the SNAT flows, the packet will be sent back to DPN1 via vxvlan tunnel-port - tunzz.

Since the packet entered DPN2 on tunzz and again sent back to same port(out_port == in_port), because of default OVS split-horizon behaiour of split-horizon, the packet is dropped.
