Unable to use mellanox NIC in loader

[andreadaoud]

Hi,

I'm using a 10G CX341a mellanox NIC, which requires mlx4 related modules to be loaded before use. But the loader doesn't seem to load it before getting IP address, so cannot get IP from this interface. Is there any solution?

Sorry, it's actually the problem of my NIC. Now it works. Thanks.

Had a test just now, it seems that ARPL is able to work with this NIC, and can get IP address on it. But when it enters Synology system, it is not detected anymore, only onboard NIC is detected and working.

I entered synology with onboard NIC, and running modprobe mlx4_en prints the log above in dmesg. I think the module probably need to be recompiled.

As synology pat has built-in mellanox mlx4_core driver, I removed mlx4_en and mlx4_core from arpl menu. This is what appears in dmesg log:

sh-4.4# dmesg | grep mlx

Thanks for the report

Please update ARPL, reboot, update modules, addons and lkm, rebuild the loader and test it.
