ConnectX-6 Dx testpmd: No probed ethernet devices

I have a centos 7.x based DPDK 22.11 build on a machine with two mellanox nics. One is ConnectX-5 Ex and other is ConnectX-6 Dx.

They both throw No probed ethernet devices on the latest DPDK version 22.11 on Centos 7. If one upgrades to CentOS 8, they work. But I need to remain on CentOS 7. Is there a workaround.

The workaround suggested in other threads does not cover meson builds.
