Is it possible to pass such a controller by PCI-Passthrough to a VM?
If it's possible, I would keep these lines.
 Uhci/Ehci only support legacy interrupts and that isn't supported by bhyve PCI passthru.
Is that a detail of the current implementation, or a fundamental limitation in the bhyve architecture?
