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.
To disable this feature, set the value to 0.
Default : 1000
