Ok I plain have no clue what is going on - please help:
Yet it is impossible to establish a link. When both cards were set in IB mode, a yellow glow could be seen at the backside of the card. In Ethernet I see nothing at all now on the card. What happens under Windows 10 is basically: no link as if cable is not attached.
"mlx5cmd -stat" results in:
...
port_state=PORT_DOWN
port_phys_state=DISABLED
---
"mlx5cmd -dbg -pddrinfo"
...
Troubleshoot Info
Status Opcode : 39
Group Opcode : 0
Message : Negotiation failure
...
So obviously link is not available.
More:
Any idea, hint,...?
