mlnx ofed

容器镜像中安装的 mlnx ofed，与宿主机中安装的 mlnx ofed 有何联系？

其实并无联系，仅仅与宿主机 mlnx 网卡型号，及其 firmware 版本有关系

以 mlnx ofed LTS version 5.4-3.1.0.0 为例，在其 Release Notes 中明确提到了该 ofed 配套的 firmware 版本

不同 OS 版本，均指向同一 Release Notes

Upgrading MLNX_OFED on a cluster requires upgrading all of its nodes to the newest version as well

This current version is tested with the following NVIDIA NIC firmware versions

Firmware versions listed are the minimum supported versions

NIC Recommended Firmware Version Additional Firmware Version Supported
cx4 12.28.2006 12.28.2006
cx5 16.31.2006 16.31.1014
cx6 dx 22.31.2006 22.31.1014

该 mlnx ofed 5.4-3.1.0.0 驱动要求的 最小 firmware 版本，但是注意到 mlnx ofed 从 5.4 版本才开始增加 minimum supported versions 的描述

与之相比，mlnx ofed LTS version 4.9-4.1.7.0 驱动要求的 firmware 版本如下
