-*   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.
