+ * entirely, and the switch features reply will not count the hidden table.

+ * However, operations that specifically name the particular table still

+ * hidden table work.
+ *
+ * To avoid gaps in table IDs (which have unclear validity in OpenFlow),
+ * hidden tables must be the highest-numbered tables that a provider
+ * implements.
+ *
+ * - "Read-only" tables can't be changed through OpenFlow operations. (At
+ * the moment all flow table operations go effectively through OpenFlow, so
+ * this means that read-only tables can't be changed at all after the
+ * read-only flag is set.)

+ * The generic ofproto layer never sets these flags. An ofproto provider can
