Intel Ethernet Controller I225-LM Support?

It shows that at all link rates?

Yes, at least for 10,100, and 1000 (both full and half duplex) it does. I don't have a 2500Base-T equipped device to test with yet. Note that ARPs transmitted from the I225-LM port to another device connected to the port are getting through to the device, but the responses back from the device do not appear to be making it back to the I225-LM as the ARP request (from the I225-LM) and reply (from the device) continuously repeat. Here is a sample from when attempting to ping the connected test device on 10.222.222.2 from pfSense:

You can see the driver supported devices here:
https://github.com/pfsense/FreeBSD-src/blob/devel-12/sys/dev/igc/igc_hw.h#L44

As far as I know though the only tested NIC is that in the 6100:
igc0@pci0:4:0:0:	class=0x020000 card=0x00008086 chip=0x15f38086 rev=0x01 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'Ethernet Controller I225-V'
    class      = network
    subclass   = ethernet
Steve

@stephenw10 can you share the options that are enabled for the I225-V with the 6100 for reference?

Yup:

@stephenw10

Thanks, I tried turning hardware checksum offloading back on again and enabled IPv6 to match as much of the 6100 config as possible, but am still seeing the same issue with the in error count increasing and no packets being successfully received by the I225-LM port:

You are talking about?:

That does seem high, especially as a percentage of the total packets received!

Yes, this is what I was referring to. The "in" packet count shows 0 on the UI though and I haven't managed to capture any inbound traffic on the I225-LM interface during testing. Note that the sysctl output and UI Status/Interfaces text capture for this interface (third text block from my previous reply) were taken a few minutes apart so the counters are not exactly the same.

Yes, but isn't the device ID difference to be expected? The I225-LM and I225-V have different IDs (0x15F2 and 0x15F3 respectively per https://github.com/pfsense/FreeBSD-src/blob/devel-12/sys/dev/igc/igc_hw.h#L44) Are there any pertinent differences in the registers between the two?

@setarcos said in Intel Ethernet Controller I225-LM Support?:

Yes it is. I'm just saying it's different to the NIC in the 6100 so it may not have been tested.

Are there any pertinent differences in the registers between the two?

I don't know. The spec sheets don't look significantly different though.

Setarcos · Jul 28, 2021, 7:44 AM

@stephenw10

Does your 6100 have any igc driver tunables set? Here is what I am currently using (defaults):

[21.05-RELEASE][root@cerberus.setarcos.lan]/root: sysctl -a hw.igc
hw.igc.max_interrupt_rate: 8000
hw.igc.eee_setting: 1
hw.igc.rx_process_limit: 100
hw.igc.sbp: 1
hw.igc.smart_pwr_down: 0
hw.igc.rx_abs_int_delay: 66
hw.igc.tx_abs_int_delay: 66
hw.igc.rx_int_delay: 0
hw.igc.tx_int_delay: 66
hw.igc.disable_crc_stripping: 0

I have a 2.5Gbe device on the way and will be able to test with that shortly, but have otherwise run out of things to try.

stephenw10 · Jul 29, 2021, 2:44 AM

Just the same default values you're using:

[21.05-RELEASE][admin@6100-2.stevew.lan]/root: sysctl hw.igc
hw.igc.max_interrupt_rate: 8000
hw.igc.eee_setting: 1

@stephenw10

My 2.5GbE device arrived today, and while the port does seem to negotiate the line rate correctly when both forced and autodetected, the original problem remains and no inbound packets from the device attached to the i225-LM port are making it through.

Just for grins I tried disabling CRC stripping with hw.igc.disable_crc_stripping=1, and while I still don't see any in packets making it through, the error in counter is no longer incrementing for every packet received as it had before.

@lra that is a good idea, but I don't have a spare system to give this a try on at the moment. I will be building a TrueNAS SCALE box in the next month or so and can give it a try then. In the mean-time I'll probably try picking up another NIC to test.

Hmm, there it's showing 0 packets received at all not just bad packets as it was before.
Was it actually connected when that was taken?

Yes, the port was actually connected to a test device and had received a few ARP replies from the test device when this was taken, but the system had been recently restarted resetting the counters and had only been online a few minutes at that point.

As another experiment, I modified the interface settings to use the second physical interface on the dual I225-LM card and it was exhibiting the same issues, but I let it sit overnight, and it does appear to have accumulated errors after all:

I decided to go a different route and picked up an X710-T2L and will be returning the QNAP QXG-2G2T-I225 as my return window will have closed by the time I have a chance to test this card on a Linux box to see if the issues persist. That said, I will still have the I225-LM card installed and available for testing through early next week so if you would like me to do any additional testing beforehand, please let me know.

stephenw10 · Aug 2, 2021, 4:30 PM

I'm not sure what else we can do there. It's just rejecting almost all the traffic it sees at some low level. It 'feels' like a hardware off loading issue to me. It all reports as disabled but maybe on that particular chip some register is set/not set that the driver doesn't see? No easy way to tell.

jerseymike · Aug 2, 2021, 4:30 PM

@stephenw10 Not sure if it's 100% relevant but I am using two of the single-port versions of the QNAP 2.5Gbe card, and could not get the DNS resolver to work at all. After disabling hardward crc offloading, the issue was resolved, so there's definitely something wonky with this driver/card combo.

This seems to align with @slk2k 's findings in the thread here, however, it seems to have no effect with the dual port QNAP QXG-2G2T-I225 card I have been testing with. I had initially tried disabling TX and RX CRC offloading from the UI, but later did so directly with ifconfig and both yielded the same results (no inbound packets are making it through).

@setarcos

Now that the system has been in place for a long weekend, I checked the stats and nothing is unusual - no missed packets. Things looks reasonably well (other than a crap-ton of interrupts, but that's because all the HW offloading is turned off).

But my thruput seems off. My previous modem and connection I would get a higher thruput on the speedtest (like 940M down, 42M up). Now I can't test higher than 860M down, 36M up). Might have more to do with the modem as much as the NIC ports. I get the same directly connected to the modem.

I have not, but a fair comparison would include both vanilla FreeBSD 12.2 with the igc driver added and a Linux kernel 5.10+ based distro with a variety of I225-LM and I225-V hardware. I just don't have the physical hardware to test this out in my homelab.
