Intel I225-V rev 3

CanuteTheGreat

Hello,

I have a PCI-E NIC 2.5G that identifies itself as an Intel I225-V rev 3. It works fully in Linux and shows up as a PCI device in pfsense/FreeBSD but is not usable due to an error.

I am currently on:
2.7.0-DEVELOPMENT (amd64)
built on Fri Jul 29 06:15:24 UTC 2022
FreeBSD 12.3-STABLE

pciconf -vl from pfSense 2.7.0-DEVELOPMENT
none2@pci0:1:0:0: class=0x020000 card=0x00008086 chip=0x15f38086 rev=0x03 hdr=0x00
vendor = 'Intel Corporation'
device = 'Intel(R) Ethernet Controller I225-V'
class = network
subclass = ethernet

Error (from dmesg) from pfSense 2.7.0-DEVELOPMENT:
dmesg | grep igc
module_register: cannot register pci/igc from kernel; already loaded from if_igc.ko

In Linux (5.15 kernel) it works in 2.5gigabit mode and does not produce any errors during my testing (on same host machine).

From reading through the forum posts regarding the I225-V, it seems like it should be working with a 2.7.x snapshot - but then again I didn't see any mention of a rev 03 specifically so maybe that's the issue?

Any suggestions? Thanks!

Rev. 3 is what you want to see there. The earlier revisions had known issues.

igc0@pci0:4:0:0:	class=0x020000 card=0x00008086 chip=0x15f38086 rev=0x03 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'Ethernet Controller I225-V'
    class      = network
    subclass   = ethernet

Are you trying to load the kernel module at boot? This error looks odd:

module_register: cannot register pci/igc from kernel; already loaded from if_igc.ko

Looks like it has an unknown PHY so the same as this:
https://forum.netgate.com/topic/171224/i225-v-is-really-an-i225-it-and-needs-a-patch

Can you try 22.05? That patch is present there.

Yes I had tried loading at boot as one of the list of things from one of the other forum posts. I have done a fresh install and tried to upgrade to pfSense Plus but ran into an issue upgrading so I have opened a ticket for that. I'll come back to this issue once that roadblock has been resolved.

Okay, so I'm now on 22.09-DEVELOPMENT and the I225 is working correctly! Thanks!
