Wait.. So if it truely has nothing to do with the existing mellanox driver, then nothing more than the fpga loader should be in the mlx5 directory? > One flavor of the product, the Innova Flex, allows customer logic in the > FPGA.

The FPGA subsystem already has APIs for partial reconfiguration use cases, you probably should not re-invent that under the mlx5 driver. Jason
