Driver Load Upon System Boot

Upon system boot, the Mellanox drivers will be loaded automatically.
To prevent the automatic load of the Mellanox drivers upon system boot:
1. Add the following lines to the "/etc/modprobe.d/mlnx.conf" file.
blacklist mlx4_core
blacklist mlx4_en
blacklist mlx5_core
blacklist mlx5_ib
2. Set "ONBOOT=no" in the "/etc/infiniband/openib.conf" file.
3. If the modules exist in the initramfs file, they can automatically be loaded by the kernel.
To prevent this behavior, update the initramfs using the operating systems' standard tools.
Note: The process of updating the initramfs will add the blacklists from step 1, and will prevent
the kernel from loading the modules automatically.
