From: Jack Morgenstein <[email protected]> Port mask now has additional state. Port can be set as "none". In this case neither the mlx4_en or mlx4_ib drivers take ownership of the port. In multifunction mode there is an option to set the vfs as single ported devices. This option will be added on a later stage (in single function mode, both physical ports belong to same function)
