In the current fsl_rio implementation initialization enables ACCEPT_ALL
mode for the port therefore you should not have problems caused by
initial destID value. Based on your post about multiport support I think
you are close to find a source of the problem.

Are you using any switches in your setup or this is pure board-to-board
configuration?
