Hello Stephen,

Thanks for your comment.
For vfio-pci mode we can support it, but when multiple rerun dpdk-app,
In rte_eal_init the logical of vfio will reset pcie.
The firmware will be core-dump for read pcie Configuration Space, when =
the
pcie is in reset state.
This bug is resolving and testing, so that this code just support =
igb_uio.
Until the test has been finished, I will add vfio-pci ability.
Do I need add this ability of vfio in this patch ?

Regards Wenbo

Will this driver work with VFIO? Vfio is preferred over igb_uio.
