Public bug reported:

When tunneling is used for tenant networks, packets are tagged with
local VLAN before they are pushed to the patch port leading to br-int.
In case of physical bridges (flat and vlan network types), packets are
switched to br-int untagged or tagged with VLAN from physical network
and br-int changes the VLAN tags. This is not consistent with tunnel
network types and causes troubles to ovs firewall.
