No!

br0 does NOT sit between eth0 and the NIC.  eth0 still represents the
NIC.  br0 sits on top, and represents the combined traffic stream from
eth0 and all other bridge ports.  By adding eth0 to the bridge, you
told it to forward all incoming frames to br0 which is the next higher
layer in the virtual interface hierarchy.
