I have a Mellanox MCX456A-ECAT ConnectX-4.
Motherboard is SuperMicro SYS-5018D-FN4T.

What do I need to get this NIC to show up as an interface?

TIA

You have to load mlnx5 driver. Just search for Connect x3 and replace with 5

Is this still valid for mlnx5?

Do I still need cli or can I use the GUI (System Tunables) to add mlx5en_load=“YES“

You can try via GUI but I think it has to be loader.conf.local (which always stays untouched)

No, GUI works fine nowadays.

When I try to execute this command:

flint_ext -d pci0:4:0:0 q
I get an error:

"libstdc++.so.6" not found, required by "flint_ext"
How do I fix?

Do not install incompatible FreeBSD binaries...

Without flint, how else can you update the firmware of the Mellanox nic?
btw, I'm using the instructions from @mimugmail blog post.

I had to use CLI, the GUI did not work.

It's a blog post, not official or supported

As the vendor software is out of control this might never be officially supported. Perhaps you can boot a Linux live CD and do the nic upgrade there

@mimugmail Great idea on the Linux live cd
