Hi, Guys,
I'm trying to run a DPDK(1.7.1) application that has been previously tested
on Xen/VMware VM's. I have both iommu=pt and intel_iommu=on.
I would expect things to work as usual but unfortunately the VF I'm taking
is unable to send or receive any packets (The TXQ gets filled out, and the
packets never leave).

Looking at the demise I se this:
IOMMU: hardware identity mapping for device 0000:83:00.0
IOMMU: hardware identity mapping for device 0000:83:00.1

These are the bus addresses of the physical functions.
I don't know If I need to see the VF's listed here as well.

Any suggestions?
