Symptoms

Cause

The latest version of mlx5_core driver (5.8-2.0.3) is not compatible with older firmware versions on Dual Port 100/25GbE I/O card (CPAC-2-100/25F and CPAC-2-100/25F-B) and Dual Port 40GbE I/O card (CPAC-2-40F-B, CPAC-2-40F-C).

The problem has been confirmed with mlx5_core driver 5.8-2.0.3 and network interface cards using firmware version 12.12.3072 or 12.17.1026. (Note that any firmware version prior to version 12.26.6402 should be updated.)
