+"""Rx/Tx queue start and stop functionality suite.

+This suite tests the ability of the poll mode driver to start and
+stop either the Rx or Tx queue (depending on the port) 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.
