The vlan tags are clearly being received correctly.  In your previous
message it also looks like everything is operating correctly.  It
appears that the configuration was changed for output that you posted
in this message.

I think that your ports are configured as access ports.  You can see
that when an untagged packet comes in and is flooded it is tagged
before being output to br0, which is presumable a trunk port.
However, access ports should not receive tagged packets, which would
explain why it gets dropped in the second case.

Please post the output of ovs-vsctl list port.
