继续安装OFED，但是kernel不支持，先增加kernel模块，缺少装啥即可

# yum install kernel-devel-4.18.0-305.19.1.el8_4.x86_64 kernel-rpm-macros

# bash mlnx_add_kernel_support.sh -m ./
Note: This program will create MLNX_OFED_LINUX TGZ for rhel8.1 under /tmp directory.

Checking if all needed packages are installed...
/lib/modules/4.18.0-305.19.1.el8_4.x86_64/build//scripts is required to build mlnx-ofa_kernel-modules RPM.
Please install the corresponding kernel-devel RPM.

Error: One or more required packages for installing OFED-internal are missing.
Please install the missing packages using your Linux distribution Package Management tool.
Run:

再继续安装

./mlnxofedinstall --add-kernel-support

驱动需要重启Server次阿能生效，注意IB的VF路径与RDMA卡是不同的
