Hardware tx checksum offload does not work properly in this scenario, so it is advisable to disable tx checksum offloading in virtual machines which connect to vifs mapped to a vlan or a trunk port to which untagged ports are also bridged. In my personal testing of OVS the same applies.

Again, that's simply not true or, at best, what you're describing is a
generalization from a specific NIC/driver issue that you've seen.
