Hi,
I guess this is my fault, the system for which the card was intended, did not post with the card.
I have therefore updated the firmware of the card in another system, which solved the problem, but since then, the card has no MAC addresses.

How can I fix this?

There is no GUID sticker on the card, can I use any other one?
This is the only MCX51A-CDAT I have, where do I get a suitable ini file?
Can anyone help?

use flint with -guid and -mac option to reflash firmware should work, you don't need ini file .
for the guid value and mac values , copy your 516a-cdat's guid and mac ,then slight change some digital(one or two is enough)

I have no other 516a-cdat, I found one in the forum
Just one command was enough

flint -d /dev/mst/mt4121_pciconf0 -guid 0x1c34da71b83a -mac 0x1c34da71b83a sg

Now it looks better, both ports are connected and have a MAC address.
Do I need the Device and Image VSD?

mst status shows only one device, shouldn't there be two?

# mst status

thanks for clarification, I only had the CX3 before.
Unfortunately, there are more differences, the CX5 requires the MLNX_OFED for SR-IOV, I thought it will work with mlx5_core.
This limits me to MLNX_OFED compatible distros, is there a chance that this will change in the future?

edit: just found out SR-IOV works with mlx5_core, all docs I found just referenced the mlnx-ofed driver

edit2: doesn't seem to work after all with SR-IOV and MLX5_Core, I can create the virtual adapters and pass them through to Windows , but I get a code 10 after installing the driver in Windows
