Switch Mellanox Card to eth Mode

Playing around with an old NX-2000 series server and it seems I need to make my 10GbE nics default to eth now while before on boot they seemed to be recognized in eth mode.

New module:

# modinfo mlx4_core
filename: /lib/modules/4.19.0+1/kernel/drivers/net/ethernet/mellanox/mlx4/mlx4_core.ko
version: 4.0-0

Old module:

# modinfo mlx4_core
filename: /lib/modules/4.4.0+10/updates/mlx4_core.ko
version: 3.4-1.0.0

Booted to a Kubuntu 16.04 Live CD to attempt to do it with the last supported firmware for the card but the Mellanox card doesn't seem to be supported by Mellanox OEM software. MLNX_OFED_LINUX-4.7-

root@kubuntu:~# mlxfwmanager --query

root@kubuntu:~# mlxconfig -d /dev/mst/mt26418_pci_cr0 set LINK_TYPE_P1=2 LINK_TYPE_P2=4
-E- Unsupported device

Tried adding to /etc/modprobe.d/mlx4_core.conf
options mlx4_core port_type_array=2

Also tried
options mlx4_core port_type_array=2,4

How can I get this card to default to eth mode on boot?

Hi @enderst 

You would need to place a call with Nutanix support on this one. Thanks
