I did more research on this issue.
First why would you want both interfaces on the same subnet?
If you must have them on the same subnet, (I don't see any advantage)
see below, it will take some work to accomplish bridging!

This URL will give you an idea about what is involved.
In CentOS, bridge-utils are available.
I did a "yum search bridge-utils"
bridge-utils-devel.i386 1.0.4-4 base
Matched from:
bridge-utils-devel
The bridge-utils-devel package contains the header and object files
necessary for developing programs which use 'libbridge.a', the
interface to the linux kernel ethernet bridge. If you are developing
programs which need to configure the linux ethernet bridge, your
system needs to have these standard header and object files available
in order to create the executables.
Install bridge-utils-devel if you are going to develop programs which
will use the linux ethernet bridge interface library.
