Bug Description

Any VF that I bind to vfi-pci gets handled as secondary queue.

Here with a mix of vfio-pci assignments: Log: http://paste.ubuntu.com/25514394/

I checked, if I bind ALL to thunderx-nicvf then ALL are considered primary and work to initialize in testpmd.
Also the example at http://dpdk.org/doc/guides/nics/thunderx.html#example-device-binding clearly points to vfio-pci.

Vice versa if I bind ALL to vfio-pci, then ALL fail - see http://paste.ubuntu.com/25514438/

ThunderX Checks are good and regression checks (on PPA) are good, uploading.

This bug was fixed in the package dpdk - 17.05.2-0ubuntu1

---------------
dpdk (17.05.2-0ubuntu1) artful; urgency=medium

  * New upstream stable release 17.05.2 (LP: #1716667)
    In Debian we moved already to 17.08.x in experimental so no syncs anymore
    for Artful. This fixes a lot of issues, for an overview see the announce
    mail at: http://dpdk.org/ml/archives/announce/2017-September/000144.html
  * d/p/bug-1716666-eal-pci-introduce-a-PCI-driver-flag.patch,
    d/p/bug-1716666-net-thunderx-manage-PCI-device-mapping-for-SQS-VFs.patch:
    let devices flag to not be unmapped e.g. needed for thunderX secondary
    queues (LP: #1716666).
  * d/librte-ethdev17.05.symbols: add rte_eth_tx_done_cleanup which was
    exported but missing in the maps, that got fixed in 17.05.2 - adapt the
    symbols file to be correct.
