-Observe that:
-
-*   rte_pci_probe()  parses the devices on the PCI bus and initializes recognized devices.
-
 The next step is to configure the RX and TX queues.
 For each port, there is only one RX queue (only one lcore is able to poll a given port).
 The number of TX queues depends on the number of available lcores.
