Hi All,

Does it mean that my card is unrecognized? It supposed to be 10GB x 2
Infiniband PCI-E HCA 500EX-D Dual-Port Card Mellanox Firmware. Currently
the card doesn't show when doing ifconfig. What should I do to have the
proper device name instead of none1 or for the card to appear in ifconfig?

mlx5en is for ConnectX-4. I think that's an older card. Try mlx4en,
which supports ConnectX-2 and ConnectX-3.
From a quick grep this infact should be supported by the mlx4/mlx5en
drivers:
net/mlx4/main.c: /* MT25408 "Hermon" SDR */
net/mlx4/main.c: /* MT25408 "Hermon" DDR */
net/mlx4/main.c: /* MT25408 "Hermon" QDR */
net/mlx4/main.c: /* MT25408 "Hermon" DDR PCIe gen2 */
net/mlx4/main.c: /* MT25408 "Hermon" QDR PCIe gen2 */
net/mlx4/main.c: /* MT25408 "Hermon" EN 10GigE */
net/mlx4/main.c: /* MT25408 "Hermon" EN 10GigE PCIe gen2 */
Thank you Gary and Rod for your quick reply. 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

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
