Prevent calling rte_eth_xstats_get not initialized dev
DPDK API forbids calling rte_eth_xstats_get on a port which has not been setup up yet. Citing the DPDK docs (reformated): " The functions exported by the application Ethernet API to setup a device designated by its port identifier must be invoked in the following order: rte_eth_dev_configure() rte_eth_tx_queue_setup() rte_eth_rx_queue_setup() rte_eth_dev_start() Then, the network application can invoke, in any order, the functions exported by the Ethernet API to get the MAC address of a given device, to get the speed and the status of a device physical link, to receive/transmit [burst of] packets, and so on. " original can be found here: http://dpdk.org/doc/api/rte__ethdev_8h.html#a36ba70a5a6fce2c2c1f774828ba78f8d Change-Id: I91854b8b0dd12dd028b4b36665cca49f16eac24c Signed-off-by: Szymon Sliwa <szs@semihalf.com>
