Can Linux Bridging operate like a Repeater?

I have been playing with the Linux bridging support, and it is doing
what bridges are supposed to do with frames that have both the source
and destination MAC addresses on the same side of the bridge, namely
NOT forward them to the other side of the bridge.

But, I am wondering if it is possible to force the bridge to forward
these frames to the other side of the bridge anyway, so it would act
more like a repeater?

I am trying to build a wireless sniffer that can forward all traffic
on a wired network over a wireless link by using a wireless bridge
from the LinuxAP project (which has the Linux bridge code in it).

If the bridging approach is the wrong one, any other suggested
approaches?
