/** \brief Finish enqueueing one buffer forward in the graph.
 Standard single loop boilerplate element. This is a MACRO,
 with MULTIPLE SIDE EFFECTS. In the ideal case,
 <code>next_index == next0</code>,
 which means that the speculative enqueue at the top of the single loop
 has correctly dealt with the packet in hand. In that case, the macro does
 nothing at all.

 @param vm vlib_main_t pointer, varies by thread
 @param node current node vlib_node_runtime_t pointer
 @param next_index speculated next index used for both packets
 @param to_next speculated vector pointer used for both packets
 @param n_left_to_next number of slots left in speculated vector
 @param bi0 first buffer index
 @param next0 actual next index to be used for the first packet

 @return @c next_index -- speculative next index to be used for future packets
 @return @c to_next -- speculative frame to be used for future packets
 @return @c n_left_to_next -- number of slots left in speculative frame
