I don't seem to have mlx4 in my /boot/kernel. I unloaded mlx5 and mlx5en and tried to load mlx instead, but strangely, it says mlx is already loaded. How? # kldload mlx kldload: can't load mlx: module already loaded or in kernel # kldstat Id Refs Address Size Name 1 22 0xffffffff80200000 1f67a88 kernel 2 1 0xffffffff82169000 316708 zfs.ko 3 2 0xffffffff82480000 cb78 opensolaris.ko 4 1 0xffffffff8248d000 42c28 mps.ko 5 1 0xffffffff82621000 bdb0 if_lagg.ko 6 1 0xffffffff8262d000 3650 ums.ko 7 1 0xffffffff82631000 6679 nullfs.ko 8 1 0xffffffff82638000 bdfe unionfs.ko # ls -l /boot/kernel/mlx mlx.ko* mlx5.ko* mlx5en.ko* Anyways, mlx seems to be rather unrelated to this problem: https://www.freebsd.org/cgi/man.cgi?query=mlx Looks like mlx4 is available in the kernel: https://github.com/freebsd/freebsd/tree/master/sys/modules/mlx4 However, it seems that it may not compile: https://forums.freebsd.org/threads/mellanox-mt26448.64350/ Does it mean, that mlx4 is no longer compiled in the default kernel and I would need to compile the kernel manually? Can I just compile the mlx4/en/ib kernel module without having to compile the whole kernel? Thanks GrzegorzJ
