From: Jakob Meng <[email protected]> In a scenario where OVN does load balancing and then SNAT with a OVS userspace datapath [0], the recirc_depth may be greater than 6. In that case, ovs-vswitchd might drop packets and raise warnings:
dpif_netdev|WARN|Packet dropped. Max recirculation depth exceeded. Increasing MAX_RECIRC_DEPTH to 8 solves this issue.
