It seems that this scenario doesn't expect some scenarios like DVR
and multiple NIC. I thought that the queue should be set in br-int
with veth(instead of patch port) between br-int and bt-tun. However,
I guess that this may occur a issue that traffic cannot turn back in
br-int. That may happen in Scenario2 case.<br>
<br>
Therefore, I think that we should set the queue to physical port but
we have a problem how do we specify the NIC in some cases(vlan,
vxlan, DVR mode router and DVR FloatingIP).<br>

I think we cannot manage this case because we doesn't know MAX
bandwidth of traffic in br-int and the bandwidth is usually enough.<br>
We should focus our attention on a case that the traffic goes out to
other nodes.<br>
