I should have tried this before emailing. kldload mlx5 generates kernel messages: mlx5_core0: <mlx5_core> mem 0x14082000000-0x14083ffffff at device 0.0 on pci1 mlx5_core0: INFO: mlx5_port_module_event:696:(pid 12): Module 0, status: unplugged mlx5_core1: <mlx5_core> mem 0x14080000000-0x14081ffffff at device 0.1 on pci1 mlx5_core1: INFO: mlx5_port_module_event:696:(pid 12): Module 1, status: unplugged but ifconfig does not report any new devices. So why doesn't module mlx5 load automatically? And what are the ifconfig device names?home | help
