+            A number of flows as a nonnegative integer.  This sets number
+            of flows at which eviction from the kernel flow table will
+            be triggered.
+            If there are a large number of flows then increasing this
+            value to around the number of flows present
+            can result in reduced CPU usage and packet loss.
