In an ovn gateway node with DPDK, the RECIRC_DEPTH may be greater than 5. Scenes: VM ping self floating IP, or VM ping Floating IP of VMs with the same network. It need process UNDNAT SNAT in LRouter egress and UNSNAT DNAT in LRouter ingress, and output to geneve tunnel also need recirc. This has an WARN: dpif_netdev(pmd36)|WARN|Packet dropped. Max recirculation depth exceeded. Signed-off-by: Guoshuai Li <ligs@dtdream.com> --- lib/dpif-netdev.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
