Hi, I am having some trouble getting a newly installed Supermicro AOC-STG-i2T 10-Gigabit NIC up and working . I have tried quite a few solutions suggested on this forum and elsewhere to activate this network card, but none of them have worked. Can somebody please help resolve this issue?

System:
PVE version: proxmox-ve: 7.3-1 (running kernel: 5.15.83-1-pve); pve-manager: 7.3-4 (running version: 7.3-4/d69b70d4)
Motherboard - Supermicro X11SCL-F
Hard disk controllers (passthrough to TrueNAS) - AOC-S3008L-L8e (Low profile Gen 3 PCI-E x8)
Network card - AOC-STG-i2T / Rev. 2.01 / PCI-E x8 2.1 (2.5GT/s or 5GT/s)

Here are the things that I have done so far:
  • Installed the latest BIOS, Proxmox (no subscription repositories), Intel driver (ixgbe version 5.18.6 - X540AT2)
  • The network page didn't list newly installed 10G ports, so I updated the network interfaces by adding a line in the etc/network/interfaces. Thanks to discussions on this forum; otherwise, I wouldn't have known that device names can be found on the dmesg | grep ixgbe output.
dmesg | grep ixgbe

  • Upon further research, I noticed that my 10Gig ethernet adapter is in the same group as the SAS controller. I read somewhere that being in the same IOMMU group could potentially result in conflict, passed this command pcie_acs_override=downstream (with and without multifunction, but it didn't change the grouping). Also, switching to another physical (PCI-E) slot didn't affect the group. I would prefer to use this as virtual port than passing it through to TrueNas.

  • To rule out any potential failure of the adapter, I plugged it into a Windows machine and installed Intel PRO drivers. The device worked perfectly.
  • The other thing that is very confusing is the device name. Not sure why "enp2s0f1" doesn't show up on multiple commands, for example, networkctl (it looks very different)

You haven't told your machine to start the interface - you need 'auto enp2s0f0' and 'auto enp2s0f1'.

Try 'ip link set enp2s0f0 up' and then run ethtool or mii-info.

Personally, I detest the 'meant-to-be-persistent-but-changes-more-than-anything-else' enxxxx naming. If you want to stop that from happening, and go back to the eth0/eth1/eth2 etc naming, you can add net.ifnames=0 biosdevname=0 to your grub configuration. Note that it will break your existing configuration, so make sure you have console access to the machine to rename eno1/eno2 after it's rebooted.

Regarding the naming convention, thanks for the tip. In the current state, how do I map the enp2s0f1 to devices listed on the networkctl?
 
Did you check from the truenas side if the card shows up there? Suspect the network card is caught up with the passthrough.

Yes, it does, if I pass it through as pcie device. However, even after updating the ip configuration, there was no up link. Hence reverted it to original state and started setting up on the pve.

I do suspect it's the issue with the passthrough as it is in the same group as the sas controller. As you can see above, the command to break the device didn't work. How do I isolate the 10G adapter into its own group?

The card is passhrouh a vm (vfio-pci), so detached from the host.
It could be iommu group sharing indeed, if you only passthrough a sas controller.

Maybe try to not start vm with pci passthrough at boot to be sure.

Thanks all for your support. The issue was clearly due to the IOMMU group. I got excited for a moment when I saw both 10G ports listed on the network page, only to realize that TrueNas was already down. There simply isn't any way to resolve this conflict (without the processor supporting the ACS feature), not even by changing the physical slots. However, the good news is that TrueNas can access the 10G ports (as a direct passthrough). My only gripe is that the second port of the 10G adapter has no utility, which I was initially planning to dedicate to another VM (Windows).

I am about the purchase a super micro blade server with this nic card (AOC-ATG-I2T2SM-O). At the end its working and appearing in your network list in proxmox server? just want to make sure before I send the PO to supplier.

thanks !
 
I'll reup this thread, because I was running into trouble with nearly the same issue. The second port did not show up after install Proxmox VE 8.2 with an Intel X540-AT2 onboard controller from Supermicro.
root@recpve1:/etc# lspci | grep 'Ethernet'
03:00.0 Ethernet controller: Intel Corporation Ethernet Controller 10-Gigabit X540-AT2 (rev 01)
03:00.1 Ethernet controller: Intel Corporation Ethernet Controller 10-Gigabit X540-AT2 (rev 01)
shows both were available.
Proxmox VE shows during install only one eno1 .

lshw showed the second port as disabled. But the logical name was "eth1" .
I checked BIOS and jumper settings everything seems to be i.O.
So I tried to add a Bridge vmbrX to my system with eth1.
No problem to save but to apply this configuration via "Apply" button failed. Because there was no such network device in Proxmox configuration.
After reboot everything worked. Both eth1 and eno1 were shown in Proxmox and both ports were online.

For me and this server the problem is fixed.
But!
In my opinion there is a bug in Proxmox VE ixgbe driver release.
