Driver for Mellanox Connectx-4 and Proxmox 6

as you know, Debian 10 is pretty new
I can't find driver for Mellanox IB QDR (ConnectX-4) AOC-IBH-X4ES Mezzanine EDR HCA

any suggestion how can I install it on Proxmox 6?

Not too sure, since I have no experience with mellanox nics - but the driver should be included in the 5.0 kernel
you can boot up the system with a live-cd and check the output of lspci -nnk
check the 'Kernel modules:' line

I hope this helps!
