- 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.
