Workaround DPDK net/virtio queue setup issue
JIRA: SAMPLEVNF-127 PROX was crashing in the VM with vector mode enabled and multiple OVS queues. This was not really a PROX bug, but a DPDK issue, which has been fixed by DPDK commit https://git.dpdk.org/dpdk/commit/?id=efc83a1e7fc3 This "net/virtio: fix queue setup consistency" is included in DPDK 17.11 and subsequent versions, and has been backported into: - DPDK 16.11.4: https://git.dpdk.org/dpdk-stable/commit/?h=16.11&id=516447a5056c - DPDK 17.08.1: https://git.dpdk.org/dpdk-stable/commit/?h=17.08&id=907fe4fc263e This means the fix is not included into any DPDK 17.02.x used by NSB. Fortunately, a simple workaround consists of calling rte_eth_tx_queue_setup() before rte_eth_rx_queue_setup(). This change implements this simple workaround, in order to make PROX work, even with unfixed DPDK versions.
