应用介绍

这篇文章描述了与其他Linux内核模块的MLNX_OFED关系的各个模块。Mellanox Connect-IB适配器卡使用mlx5_ib，mlx5_core，而ConnectX-3 / ConnectX-3 Pro使用mlx4_core，mlx4_en和mlx4_ib。

并非所有模块都需要加载，这取决于应用程序和用途（例如，如果链路层是以太网，则不需要加载mlx4_ib，反之亦然;如果链路层是InfiniBand，则不需要加载mlx4_en）。

相关 Linux commands:

• lsmod：提供当前在Linux O / S上加载的内核模块的列表。
  modprobe：用于在Linux O / S上添加或删除内核模块的命令。
  modinfo：一个命令，显示有关Linux O / S上内核模块的信息。

cat /sys/module/模块参数：

要检查模块参数的值，请运行以下命令
<module-name>/parameters/<parameter-name>

例如:

# cat /sys/module/mlx4_core/parameters/roce_mode

下图是相关MLNX_OFED模块和使用它们的其他内核模块之间的高级关系。

取决于各种发行版和用户应用程序，可能需要进行细微更改。

要查找被MLNX_OFED替换的内核模块的完整列表，请运行以下命令（或类似命令），在本例中是在RHEL7 OS中采用的：
