Sorry about that.

Basically, Linux bonding with VLANs echoes back the ARP reply and
that causes the switch to learn the MAC address in the wrong port
which leads to the problem.

We are still investigating this problem, so there is no final solution
yet.  We definitely need more info. My suggestion is to first move the
vlan from Linux bonding to OVS bridge port.  So, instead of tagging at
the bonding device, it will be done at the OVS port.

I.e.: ovs-vsctl add-port <br> <bond> -- set Interface <bond> tag=<vlan id>

If that doesn't help, then use OVS built-in bonding or remove bonding
at all.

Please provide the feedback if possible to allow us to fix the root
cause after all.

Thanks,
