Hi guys,

  Does port mirroring works on veth device which is connected on another
linux bridge?
  I have setup below mirror:
----
# sudo ovs-vsctl -- set Bridge br-int mirrors=@m -- --id=@qvod870e7d0-21
get Port qvod870e7d0-21 -- --id=@qvoa57385cb-1b get Port qvoa57385cb-1b --
--id=@m create Mirror name=mirror select-src-port=@qvod870e7d0-21
select-dst-port=@qvod870e7d0-21 output-port=@qvoa57385cb-1b

the output port qvoa57385cb-1b is a veth device, and its peer is
qvba57385cb-1b which is connected in another linux bridge qbra57385cb-1b.

# brctl show
qbra57385cb-1b          8000.c2ea90d9a704       no
 qvba57385cb-1b

                  tapa57385cb-1b


I can get the mirror packets on qvoa57385cb-1b, qvba57385cb-1b,
qbra57385cb-1b but not  tapa57385cb-1b, it it could be blocked in ovs
anywhere?

Someone has the same issue[1] as mine.
