Date: Fri, 2 Dec 2011 12:16:40 +0200 From: Yevgeny Petrilin <yevgenyp@...lanox.co.il> To: <davem@...emloft.net> CC: <netdev@...r.kernel.org>, <linux-rdma@...r.kernel.org>, <roland@...estorage.com>, <yevgenyp@...lanox.co.il>, <liranl@...lanox.co.il>, <jackm@....mellanox.co.il> Subject: [PATCH net-next V0 02/21] net/mlx4: Extending port_mask functionality From: Jack Morgenstein <jackm@....mellanox.co.il> 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 <jackm@....mellanox.co.il> Signed-off-by: Yevgeny Petrilin <yevgenyp@...lanox.co.il> --- 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(-) diff --git a/drivers/infiniband/hw/mlx4/main.c b/drivers/infiniband/hw/mlx4/main.c index 77f3dbc..6128b29 100644 --- a/drivers/infiniband/hw/mlx4/main.c +++ b/drivers/infiniband/hw/mlx4/main.c @@ -177,7 +177,7 @@ mlx4_ib_port_link_layer(struct ib_device *device, u8 port_num) { struct mlx4_dev *dev = to_mdev(device)->dev; - return dev->caps.port_mask & (1 << (port_num - 1)) ? + return dev->caps.port_mask[port_num] == MLX4_PORT_TYPE_IB ?
