I don't quite understand what this hardware is, based on your description.
Is this a specific piece of hardware that only serves as a traffic generator,
or a particular hardware feature of the DesignWare endpoint, or is it
software running on a SoC in endpoint mode while plugged into a Linux
system running this driver on the host?
Most importantly; Is there any relation between this driver and the driver
we have for the DesignWare PCIe endpoint itself?
My feeling is that this should be located more closely to drivers/pci/,
but that depends on what it actually does.
