Mellanox CX-3 Pro NIC SoC / hardware revision docs

I am unable to find a doc that explains the hardware revisions and their year of release, please help.

Hi ,

Please note that this product is end of life and end of support .
You can refer to the user manual to get this information



I have read these and others like them, they do not contain any information on PCIe card hardware revisions.
These list firmware revisions.
