mlx5 with inbox driver 100G is not detecting

Infrastructure & Networking Adapters and Cables Ethernet Adapter Cards

Hi,

I am trying to up 100G Ethernet driver. I am using inbox driver, I am not using MLNX OFED stack.

I am inserting drivers manually in the sequence of ib_cm…mlx5_core,mlx5_ib

mkdir /sys/kernel/config/rdma_cm/mlx5_0

echo “RoCE v2” > /sys/kernel/config/rdma_cm/$mlx5_0/ports/1/default_roce_mode

But with ethtool command is not showing 100G, Am I missing some thing?

root@xhdipsspdk1 mailto:root@xhdipsspdk1 ~]# ethtool enp5s0

Hi,

Please, perform the same test with MOFED in order to check if the issue related to inbox driver. I would also suggest to check the cable P/N and try connect ports in loopback ( one to another, using same cable).

Now I can able to work with Inbox and MLNX OFED stack. RHEL 7.0 and kernel 4.2

OS is Centos 7.3 at the moment, kernel is 3.10.0. Everything works as expected with MOFED (well, sort of).

5

I’ve encountered the same problem with the latest centos7 inbox rpms. Back to mofed it seems.

6

What OS and kernel are you use ?

Keep in mind that support for 25G/50G/100G was added to ethtool v4.8.

You may want to check which version your are running.
