[Bug 1853592] Re: hw-tc-offload not reliable with VXLAN
** Description changed: + [Impact] + Hardware offload VXLAN tunnel flows may not be correctly offloaded and are hence not functional in OpenStack deployments + + [Test Case] + Deploy OpenStack configured with suitable network cards for hardware offload of VM interfaces + Boot instances with hardware offloaded interfaces (capability=switchdev) + Instances may or may not get DHCP configured depending on how OpenStack chooses to tag the flows associated with the VXLAN tunnel networking for the cloud. + + [Regression Potential] + TBC + + [Original Bug Report] OpenStack Train OVS 2.12 Linux 5.3 from hwe edge Connect-X 5 running latest firmware from Mellanox.
