devlink: add parameter documentation for the mlx4 driver
The mlx5 and mlxsw drivers have driver-specific documentation for the devlink features they support. No such file was added for mlx4. Add a file to document the mlx4 devlink support. Initially it contains only the devlink parameters. Signed-off-by: Jacob Keller <jacob.e.keller@intel.com> Cc: Tariq Toukan <tariqt@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
