Thanx for the quick reply. Got that, but I still haven't solved my problem though.

Is there any way to group the packet flow without sacrificing the L2 lookup? I think that the flows to multiple ports (i.e. ovs-ofctl add-flow br0 in_port=3,actions=output:1,2)
skip this lookup.
I was thinking to add a fake bridge, remove the tag value,
and add the ports there. Would this provided the desired result?
Are there other alternatives?

While the connectivity works fine I was considering to add a flow based on
the gre key. I actually
want to group the ifaces with the same gre key so I was thinking something

#ovs-ofctl add-flow br0
tun_id=1,idle_timeout=0,priority=1,actions=set_tunnel:1,normal
(I want normal action in order to preserve L2 lookups)

The rule is created but there are no packets "caught". They always "fall
into" to the default rule.
Am i doing something wrong? I, also, noticed a message NXST_FLOW reply
(xid=0x4) when I run dump-flows.
Is it related to the problem?

You need to set the key on the port to be "flow", otherwise the key is
considered to be a property of the port itself and the tun_id is
zeroed.
