/* Logical_Flow table translation to OpenFlow
* ==========================================
*
* The Logical_Flow table obtained from the OVN_Southbound database works in
* terms of logical entities, that is, logical flows among logical datapaths
* and logical ports. This code translates these logical flows into OpenFlow
* flows that, again, work in terms of logical entities implemented through
* OpenFlow extensions (e.g. registers represent the logical input and output
* ports).
*
* Physical-to-logical and logical-to-physical translation are implemented in
* physical.[ch] as separate OpenFlow tables that run before and after,
* respectively, the logical pipeline OpenFlow tables.
