thanks for testing!

I used the debugfs interface for first testing, now I'm using custom
fpga config interface driver, but it depends on many other drivers
and won't work without additional special hardware.

I use an rbf file. The v2 patch [1] used a module parameter to specify
firmware file name for a given PCIe device, but it is bypassing the
framework and is not acceptable for mainline.

Thanks,
