Hallo Jiri, Arnaldo,
after updating Debian (probably with the advent of Python 3.8.5, guessing)
I get a wired behavior with python scripting. The error is that the python type
for prev_comm and next_comm are not strings anymore, rather bytearrays. Which
are incompatible types and scripts will not

Allow the iommu_unmap_fast to return newly freed page table pages and
pass the freelist to queue_iova in the dma-iommu ops path.
This is useful for iommu drivers (in this case the intel iommu driver)
which need to wait for the ioTLB to be flushed before newly
free/unmapped page

To facilitate code maintenance and compatibility, #1 and #2 add

querying device capabilities and specifications, then the driver

Currently, the revision of the pci device is used to identify
whether FEC is supported, which is not good for maintainability
