Hi Niklas,

The problem is that something seems to  be broken in the iommu/core
branch. Regardless of whether I have my DMA API conversion on top or
with the base iommu/core branch I can not use ConnectX-4 VFs.

Have you already tried to bisect the issue in the iommu/core branch?
The result might sched some light on the issue.

Regards,

	Joerg
