If the devices are all ending up in the same IOMMU group, then you may just
need to run DPDK without an IOMMU, which is unfortunately not ideal, but
may work for basic testing. Suggest trying to disable IOMMU in grub and
using the vfio module in noiommu mode. Are the NICs connected directly to
the CPU socket, or do they connect to a chipset? If the latter, maybe try
moving PCI slot to see if they can connect directly to CPU and so appear in
a different IOMMU group.
