[PATCH net-next V0 02/21] net/mlx4: Extending port_mask functionality
From: Yevgeny Petrilin <hidden>

Subsystem:
infiniband subsystem, mellanox mlx4 ib driver, mellanox mlx4 core vpi driver, networking drivers, the rest · Maintainers:

From: Jack Morgenstein <redacted> 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) Signed-off-by: Jack Morgenstein <redacted> Signed-off-by: Yevgeny Petrilin <redacted> --- drivers/infiniband/hw/mlx4/main.c | 2 +- drivers/net/ethernet/mellanox/mlx4/main.c | 4 +--- include/linux/mlx4/device.h | 13 ++++++------- 3 files changed, 8 insertions(+), 11 deletions(-)
