Add mlx5 internal test for map and unmap external RxQs.
This patch adds to Testpmd app a runtime function to test the mapping
API.
For insert mapping use this command:
testpmd> port (port_id) ext_rxq map (rte_queue_id) (hw_queue_id)
For insert mapping use this command:
testpmd> port (port_id) ext_rxq unmap (rte_queue_id)

+API for external RxQ mapping management.
+
+Map HW queue index (32 bit) to rte_flow queue index (16 bit) for external RxQ::

+ testpmd> port (port_id) ext_rxq map (rte_queue_id) (hw_queue_id)
+
+Unmap external Rx queue rte_flow index mapping::
+
+ testpmd> port (port_id) ext_rxq unmap (rte_queue_id)
+
+where:
+
+* ``rte_queue_id``: queue index in range [64536, 65535].
+ This range is the highest 1000 numbers represented by 16 bits.
+* ``hw_queue_id``: queue index given by HW in queue creation.
