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

[Pravein GK]

Hi Raslan,

Thanks for your reply.

The lsmod o/p is below :

$ lsmod | grep mlx5_
mlx5_ib               364544  0
ib_uverbs             131072  2 rdma_ucm,mlx5_ib
mlx5_core            1294336  1 mlx5_ib
mlxfw                  24576  1 mlx5_core
psample                20480  1 mlx5_core
devlink                45056  1 mlx5_core
ib_core               311296  8
rdma_cm,ib_ipoib,iw_cm,ib_umad,rdma_ucm,ib_uverbs,mlx5_ib,ib_cm
mlx_compat             45056  10
rdma_cm,ib_ipoib,iw_cm,ib_umad,ib_core,rdma_ucm,ib_uverbs,mlx5_ib,ib_cm,mlx5_core
ptp                    20480  1 mlx5_core

I had tried the force restart, and even after that , I get the same error.

Thanks,
Pravein
