Hi Luka,

In principle, any PCI(e) device can be controlled using pci-driver. A
standard use case would be to build a user-space NVMe driver to get
every last bit of performance out of a storage device (think SPDK).

By switching silicon, do you mean actual PCIe switches? If so, no:
pci-driver expects functions with a type 0 config space header.
