Target Milestone --- 

Debian (and probably lots of other=
 distributions), do not enable unsafe VFIO
option (CONFIG_VFIO_NOIOMMU). If that is true, then the module parameter do=
es
not exist.

This causes DPDK devbind to fail:
Error: failed to check unsafe noiommu mode - Cannot open
/sys/module/vfio/parameters/enable_unsafe_noiommu_mode: [Errno 2] No such f=
ile
or directory: '/sys/module/vfio/parameters/enable_unsafe_noiommu_mode'


This regression is caused by the commit.

    usertools/devbind: support VFIO non-IOMMU mode

    This patch adds noiommu option to dpdk-devbind.
    If the no IOMMU is detected, then if noiommu flag is set
    the vfio-pci unsafe_noiommu_mode flag is set.
