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

[Raslan Darawsheh]

Hi Parvein, 

Can you kindly confirm that the kernel drivers (mlx5_ib, mlx5_core) are loaded? 
(lsmod | grep mlx5_)

If not please try to restart the kernel driver:

/etc/init.d/openibd force-restart 

Kindest regards,
Raslan Darawsheh
