I believe it can only be consumed at the last stage of a pipeline, with possibly many sets or clears of the different fields in the intermidiate stages (i.e more than one LFB instance). > There is the question of how execute-immediate interacts with deferred > execution and whether we are having two LFBs which have to implement the > same capabilities. Section 4.8 of OF 1.1, last sentence (action list being the "execute-immediate"): "The action set of the packet is unchanged by the execution of the action list." Also it does not seem that the execute-immediate can terminate the pipeline. cheers, jamal
