Solved Is there a driver for Mellanox Connect-IB cards?

[inf3rno]

I know that there is a ConnectX driver, which works great for my 10 Gbps SFP+ cards, but I am about to move to QSFP+ 40 or 56 Gbps. I am curious if there is a driver for Connect-IB cards, especially for the MCB194A and MCB191A ones? Did anyone try them with FreeBSD?

Some Linuxes have it. It is similar to mlx5 according to them. https://github.com/theripper/linux/commit/e126ba97dba9edeb6fafa3665b5f8497fc9cdf8c I'll ask the mlx driver developers, maybe they add it or it is already supported.

According to this they work with mlx5 sort of:

Mellanox MCB193A-FCAT

But the manul does not write them:

mlx5en(4)

I got answer from Nvidia:

Connect-IB devices are not officially supported, though in theory, current driver should support them.

Meanwhile I found a good deal with ConnectX-3 cards second hand, so I decided to go with ConnectX-3 instead of Connect-IB for now. I think Nvidia would help if somebody has driver issues with this type of cards, you just need to mail them with the email address you can find in the support section here: https://www.freebsd.org/cgi/man.cgi...FreeBSD+13.0-current&arch=default&format=html
