+------------------

+Controls how often (in ms) a busy connected flow can select another tx queue.
+
+A resection is desirable when/if user thread has migrated and XPS
+would select a different queue. Same can occur without XPS
+if the flow hash has changed.
+
+But switching txq can introduce reorders, especially if the
+old queue is under high pressure. Modern TCP stacks deal
+well with reorders if they happen not too often.
