libmlx4.so missing in Mellanox 4.4.2 (–dpdk) driver packages?

Background:

RHEL: 7.5 kernel 3.10.0-862.11.6.el7.x86_64

Mellanox driver version we are trying to install: 4.4.2

When we install mellanox 4.4.2 drivers (dpdk only) on RHEL 7.5 using yum

/usr/bin/yum -d 0 -e 0 -y install mlnx-en-dpdk

It says libibverbs

Updated By: libibverbs-41mlnx1-OFED.4.4.2.0.1.44207.x86_64 (sriov_mlnx)

And we had to remove system package “libibverbs-15-6.el7.x86_64” to have “mlnx-en-dpdk” installed.

However even after installing all packages (with optionmlnx-en-dpdk ) we don’t see libmlx4.so file installed at desired location (although we see libmlx5.so)

Is that file missing to include in rpms of 4.4.2 version?

So essentially two problems here.

  1. Installation breaks with below errors when we have system installed packages

libibverbs-15-6.el7.x86_64

rdma-core-15-6.el7.x86_64

It fails with below errors:

You could try using --skip-broken to work around the problem

2.libmlx4.so library missing after installing dpdk specific packages.

Hi Kiran,

MLNX_OFED 4.4-2.0.7.0 driver is an old driver from 3 years ago that we no longer maintain or debug, as well as the mlnx-en-dpdk driver. Please try to install driver version 5.0, which is the latest version that supports ConnectX-3 NIC.

Regards,

Chen
