Hello
First, thank you for the great product you provide and the exceptional support.
I have been working on pve in my home for some time now.
I just got the Mellanox connectx-2 and can't get it to work. I'm out of ideas, I tried changing pcie slots, pcie speeds in bios. Everything gives the same result.
Nic can be detected, but no speed.
The board is a gigabyte b760m c, it has 1g nic built in, 2.5g nic in pcie x1, third mellanox + dac.
