This would require that ap_bridge_packets=0 and Linux bridge code would
be used to bridge packets back to the same interface. The default kernel
does not support this, but I have seen couple of patch files that claim
to enable this kind of mode. After this, ebtables could be used to
filter packets between the associated stations.

In other words, this is likely to require some work and kernel changes.
I have not tested this myself and I don't know whether there are any
good step-by-step instructions on this kind of change.
