There is a small error in this patch:
2016-07-04 17:16, Jan Viktorin:
> The pci_vfio_has_supported_extensions is not PCI-specific and it is a private
> function of the eal_pci_vfio.c. We just rename the function and make it
> available even for non-PCI devices.

lib/librte_eal/linuxapp/eal/eal_vfio.c:77:4: error:
implicit declaration of function ?close?
It is fixed in patch 8 with "#include <unistd.h>".
