"""In general, actual packet forwarding may have to wait until the final table
in the pipeline. This means we must determine if there is a "next" table
that processes the packet from here, or if this is the last one.
But first, the easy part. There are exactly three cases where a
forwarding table *will* in fact "immediately forward" a packet according
to the current rule (and all previous table stages that processed the
packet), without waiting for any other further processing:
(1) if the packet is dropped by the current rule,
(2) if the packet is forwarded to the controller port, or
(3) if this is the last stage of the pipeline.
In the case of (1) and (2), packet forwarding may happen immediately and
only depend on the current rule. But in (3), the forwarding decision
must take the current rule as well as previous port changes into
account, as follows:
(a) if the current rule specifies an output port, forward the packet out
of that port.
(b) if the current rule does not specify an outport, then forward the
packet out of the port using the value stored in the dedicated
per-packet port register.
If neither of (1)-(3) above is true, then we take the following
approach:
(a) if there is an outport set by this rule, write that value into the
dedicated per-packet register that contains the current port the
packet is in.
(b) if there is no outport set by this rule, and if this is table id 0,
move the value of the inport into the dedicated per-packet port
register. This denotes that the packet is currently still on its inport.
(c) resubmit the packet to the "next" table (according to the pipeline).
