+An OpenFlow 1.0 switch looks up each packet that arrives at the switch
+in table 0, then in table 1 if there is no match in table 0, then in
+table 2, and so on until the packet finds a match in some table.
+Finally, if no match was found, the switch sends the packet to the

+OpenFlow 1.1 and later offer more flexibility.  This command
+configures the flow table miss handling configuration for table
+\fItable_id\fR in \fIswitch\fR.  \fItable_id\fR may be an OpenFlow
+table number between 0 and 254, inclusive, or the keyword \fBALL\fR to
+modify all tables.  \fIflow_miss_handling\fR may be any one of the
+following:

+Drop the packet.

+1.0 switch always handles packets that do not match any flow, in
