CentOS - Nov 2017 - Possible to have EthX acting like the ipaddress of the attached device (aka bridge) having no ipaddress?

Hi

I have a Centos 6.X router/firewall/gateway for a /29 network all connected to
one ETHX that has a switch behind it.

This setup works very well but does NOT allow me to QOS one of the devices (a
VOIP phone, many lines) as for "tc" to work I need a device, not
ipaddress.

I thought to connect the VOIP phone directly to the router, but in doing so I
need that interface to ACT like the IPADDRESS of the VOIP box, meaning the
ethernet interface has no ipaddress acting like a bridge:

     Internet
       |
  ---------------------------
  |   router ip
  |
  | BRIDGE        base of /29
  ---------------------------
    |             |
    |           -------------
    |           |            |
    |           _____________
    |             |  |  |  | 
    |
  ----------------
  | phone system |
  ----------------

That way I can use "tc" to prioritize the traffic for the phone system

If there are other ways to do this, please suggest.

thanks
Jobst
