Yes, since the driver has to do this anyway, it is easy to not allow direct transmission to another station. prism2_rx() takes care of this (in the end, where skb2 is determined). I'll add an configurable option for setting whether AP passes every frame only to its own network handling or also directly back to the wireless media. Depending on the routing table setup, the AP might also need some filtering, e.g., with iptables to not allow packets routed back to the same interface.
