Hi everyone,
This is my first question I send to the DPDK users mail pool. I'm experiencing the following scenario:
I'm not able to use the mlx5 pmd driver with some Mellanox NICs I have installed on my server. The error I'm receiving during EAL initialization is:
et_mlx5: no Verbs device matches PCI device 0000:03:00.0, are kernel drivers loaded?
The DPDK version I'm currently using is: DPDK-STABLE-18.11
I have installed the OFED latest version:
mlnx-en-4.5-1.0.1.0-ubuntu16.04-x86_64
I have performed modprobe of the ib_uverbs kernel module
Here's the kernel version I'm using
moragalu at server:~$ uname -r
4.4.0-143-generic
Here are the NIC models:
moragalu at server:~$ lspci | grep Mell
03:00.0 Ethernet controller: Mellanox Technologies MT27710 Family [ConnectX-4 Lx]
03:00.1 Ethernet controller: Mellanox Technologies MT27710 Family [ConnectX-4 Lx]
06:00.0 Ethernet controller: Mellanox Technologies MT27710 Family [ConnectX-4 Lx]
06:00.1 Ethernet controller: Mellanox Technologies MT27710 Family [ConnectX-4 Lx]
The firmware version that the NICs are using:
moragalu at eridium03:~$ ethtool -i eridium25-03
driver: mlx5_core
version: 4.5-1.0.1
firmware-version: 14.24.1000 (MT_2420110034)

Hope you can help me out beacause I'm really lost here :) Thank you in advance.
