pciutils built without libkmod support

[FedericoRessi]

This bug has to be probably workaround as it is expected to hurt compute node when using Ubuntu.

https://bugs.launchpad.net/ubuntu/+source/pciutils/+bug/1516095

Proposed workaround for it is running following just before stacking:

sudo /opt/stack/DPDK-*/tools/dpdk_nic_bind.py –b ixgbe <pci_address>

Where would be one of following:

According last conversation I had on this issue this should not affect this workflow if devstack is used to launch openstack and ovs-dpdk.
