Upgrade the NIC driver to improve network performance, enhance compatibility, and fix known issues. You need to upgrade the NIC driver only for Mellanox NICs.

2. Install the required software dependency packages.

   yum install createrepo python3-devel lsof tcsh pciutils-devel fuse-devel gdb-headless make kernel-devel-`uname -r` gcc python3-unversioned-command autoconf automake patch rpm-build -y

3. Install the driver.

   tar -xvf MLNX_OFED_LINUX-5.8-3.0.7.0-openeuler22.03-aarch64.tgz
   cd MLNX_OFED_LINUX-5.8-3.0.7.0-openeuler22.03-aarch64
   unset GOMP_CPU_AFFINITY
   ./mlnxofedinstall --all --upstream-libs --add-kernel-support

4. Update initramfs to ensure that the new driver is correctly loaded.
