[ovs-dev] Can I use dummy-type bridge together with netdev-type bridge for test?

[Sam]

Hi all,

I want to test dpdk based bridge, which is bridge in netdev type datapath,
but in this mode I could not use dummy port (As dummy port could send
packet directly, and lots of ovs test cases use this port, so I want to use
it).

So I start ovs with dpdk option and dummy option, and then create two
bridge (one is dummy type, one is netdev), and use patch port to connect
them, and add normal flow to them.

But when I send packets use `ovs-appctl dummy/receive ...` into dummy-type
bridge, the netdev-type bridge could not receive packet and also could not
send this packet from other port (dummy-type port, patch type port and
netdev-type port are all link up).

I don't know why and how to fix this bug? Thank you~
