When a VM sends an ARP or an ND NS for its own IP address, it is trying to
check for a duplicate address in the network. OVN needs to suppress the

It will also solve a problem when there are nested VMs (or network
namespaces) within the source VM, connected to VM port by a bridge inside,
sending ARP for the VM's IP, they would get duplicated responses.
Thanks for the review.
I'm hoping to hear from Valentine whether this fixes the originally
reported problem in practice.
First of all, thanks for the patch. In fact, we tried a pretty similar
approach yesterday, and it seemed to help. Your patch solves the problem
as well.
