Hi,
I'm testing openstack ussuri deployment with ovn ml2 driver (versions at the
end of the email) and seeing an unexpected behavior when sending ARP requests.

used for is SNAT and/or SNAT+DNAT for overlay networks.

entirely convinced that's the case given that ICMP traffic is being
forwarded - I see how it's doing what programmed flows are telling it to do,
but that doesn't seem to be expected result.

Once I restart ovn-controller it recalculates local ovs flows and the problem
is fixed so I'm assuming it's a local problem and not related to NB and SB
databases.

This seems to be working fine in my lab (there is access to the management
interface - vlan10 - even when bond0 has ovs-system as master), but are there
any drawbacks to such a configuration?

nowhere enough to stop it from processing other packets (ovs-vswitchd
logs don't report increased CPU usage).
openvswitch version: 2.11.0
ovn version: 20.09.90 (a build from 20.09 branch from 2020.12.07)

internals knowledge would have to chime in on this one.

When running scale tests for ovn with kubernetes with hundreds of nodes, how
are cluster upgrades handled?

distributed - instead all traffic is centralized on the gateway chassis node
that is assigned to the LAN router.
It feels like it should work and it's either a bug in my setup, or omission in
ovn code, where it can't tell that the traffic could be decentralized.
