Comment 3 for bug 1836682

Assigning to Chenjie to review and check if there is something missing with the steps for the pci-pt case, similar to the sr-iov config (https://bugs.launchpad.net/starlingx/+bug/1835318)

Perhaps this is a case where a data network was not created (which is a known limitation)

It would be great to document the steps at: https://wiki.openstack.org/wiki/StarlingX/Networking#Useful_Networking_Commands
