+ Build support for the Innova family of network cards by Mellanox
+ Technologies. Innova network cards are comprised of a ConnectX chip
+ and an FPGA chip on one board. If you select this option, the
+ mlx5_core driver will include the Innova FPGA core and allow building
+ sandbox-specific client drivers.
