The FPGA is indeed a bump-on-the-wire.

to perform real programming)

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. But even then it is "wrapped" by Mellanox shell logic.
We plan to have an in-kernel API for writing client drivers for Innova
Flex.

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