Hi folks,

   Seems it works with the same datapath type during the discussion in [1]
by finally done a flow of leaving two kernel netdev port communicate
together.

   But in my case I have a setup with two bridges has different datapath
type, netdev and system, need to be connected, port_A(in netdev datapath)
is in running in the userspace, port_D(in system datapath), will the flow
be port_A ---- port_D directly and packets go through userspace to
kernelspace and so on in the reverse direction,
 does patch port can make it work?

The topology is
*port_A --- br1(netdev) --- port_B (patch) ........ port_C (patch) ---
br2(system) --- port_D*
