I am testing a Mellanox ConnectX-4 NIC with mlxlink.
I have another NIC setup to 25G without auto-negotiation and without FEC. It is connected to the ConnectX-4 using DAC. PRBS31 test work successfully and without errors. However, mlxlink suggests that there is a compliance code mismatch between the module and the port configuration with opcode 16, group PHY FW. What does it mean?
I just noticed I using a 10G cable and will soon try with a 25G cable. I guess I was confused since the supported cable speed printed by querying the device is (25G, 10G, 1G). I will update.
