Dependencies can be installed from RPM packages. I will add those
information in new patch version.

 It would be possible to probe it as a standard PCI device, but as this
szedata2 driver uses libsze2 library it needs to pass some parameters to
the library and we thought that using vdev would be the easiest solution.
Is there a way how to provide parameters to pdev driver?
We also work on a new PMD which will eliminate dependencies on kernel
modules and libsze2, and using this PMD COMBO card will be probed as a
standard PCI device.

Best regards,
