Intel I225-LM support and configuration

[DoctorB0NG]

Is the Intel I225-LM supported in TrueNAS-12.0-U6? This is obviously not official but someone in another thread was stating the drivers were included in 12.0 U6: https://www.truenas.com/community/threads/intel-2-5gbe-lan-chip-not-recognized.94165/#post-659269

I took a quick look through the TrueNAS git repo and it looks like there was a commit that adds support. I've added the system tunable per the note:

https://github.com/truenas/os/blob/d7388d33b4ddffb8900b511ae767875916dd5126/share/man/man4/igc.4


Alternatively, to load the driver as a module at boot time, place the following line in loader.conf: if_igc_load="YES"

Unfortunately the device is not showing up under Network > Interfaces. Here is the output from lspci where the device is showing up:

Code:

03:00.0 Ethernet controller: Intel Corporation Device 15f2 (rev 03)
        Subsystem: Device 1baa:c001
        Flags: bus master, fast devsel, latency 0, IRQ 16

        Capabilities: [70] MSI-X: Enable- Count=5 Masked-

Any insight is much appreciated. Thanks!

Well, what happens if you try to load the module manually? ("kldload if_igc.ko" or whatever)

if_igc.ko isn't packaged with TrueNAS, unfortunately. I don't see it in my 12.0-U6 installation in /boot/kernel, /boot/modules, or compiled into the kernel.

That would explain why the loader tweak isn't working, then.
