[dpdk-users] common_mlx5: Failed to load driver = net_mlx5 Error

[Pravein GK]

Hello All,

I am using DPDK 20.08 with Mellanox Connect X 5 NICs.
I have installed the latest OFED drivers with "--dpdk --upstream-libs".
However, while launching a dpdk application, I get the below error :

EAL: Detected 24 lcore(s)

I am stuck with this error, and unable to proceed for a long time despite
trying most of the things suggested in forums. Please help.

Thanks,
