title: Exposing Tap interface from docker container to docker host
body: <p>my application creates a tap interface inside a docker container. 
  e.g. tap_1: ip: 192.168.2.1</p>
  
  <p>My requirement is that any packet coming on docker host can be directly sent to tap interface which is present inside the docker container. I am basically try to avoid one hop of sending first to docker0 and then forward it to specific tap interface.</p>
  
  <p>I tried going through pipeworks and bridge network, but seems none of them can resolve my requirment.</p>
  
  <p>Appreciate your help.
  Thanks
