+"""Rx/Tx queue start and stop functionality suite.
+
+This suite tests the ability of testpmd to start and stop
+either the Rx or Tx queue during runtime, and verify that
+packets are not received when one is disabled.
+
+Given a paired port topology, the Rx queue will be disabled on port 0,
+and the Tx queue will be disabled on port 1.
