Please note that this mailing list is about one particular driver, not 
about wireless networking in general.  You may get better responses if 
you ask in a better place.

The ad-hoc interface doesn't support bridging, and that's a fundamental 
limitation on 802.11 protocol.  It can only be circumvented by using WDS 
frames with 4 addresses, but this is not standard.  All stations would 
have to support it.

Since bridging is impossible, routing appears to be the only option.
