ethdev: get default Rx/Tx configuration from dev info
Many sample apps use duplicated code to set rte_eth_txconf and rte_eth_rxconf structures. This patch allows the user to get a default optimal RX/TX configuration through rte_eth_dev_info get, and still any parameters may be tweaked as wished, before setting up queues. Besides, if a NULL pointer is passed to rte_eth_rx_queue_setup or rte_eth_tx_queue_setup, these functions get internally the default RX/TX configuration for the user.
