-/* Function to combine actions from following device/port with the current
- * device actions in openflow pipeline. Mainly used for the translation of
- * patch/tunnel port output actions. It pushes the openflow state into a stack
- * first, clear out to execute the packet through the device and finally pop
- * the openflow state back from the stack. This is equivalent to cloning
- * a packet in translation for the duration of execution.
+/* Function handles when a packet is sent from one bridge to another bridge.
  *
- * On output to a patch port, the output action will be replaced with set of
- * nested actions on the peer patch port.
- * Similarly on output to a tunnel port, the post nested actions on
- * tunnel are chained up with the tunnel-push action.
+ * The bridges are internally connected, either with patch ports or with
+ * tunnel ports.
+ *
+ * The output action to another bridge causes translation to continue within
+ * the next bridge. This process can be recursive; the next bridge can
+ * output yet to another bridge.
+ *
+ * The translated actions from the second bridge onwards are enclosed within
+ * the clone action, so that any modification to the packet will not be visible
+ * to the remaining actions of the originating bridge.
