Intel I226-V input errors / slow WAN speed

[stefan00]

Short Description:

New OPNSense install on current intel hardware, based on some china board. Mainboard Embedded are

- 4 x Intel X710 10G SFP+ and
- 6 x Intel I226-V 2.5G interfaces

The I226-V interfaces show input errors. As one of the symptoms, WAN download speed drops from ~500MBits to ~25MBits when using a I226 interface as gateway.

At this point, it seems unclear whether the problem is hardware or igc driver related.

Long story:

Connecting anything to any I226 Port causes input errors. Errors are reported as sysctl dev.igc.5.mac_stats.missed_packets and input errors at ifinfo. X710 Ports work perfect.

There is no significant difference whether:

Cabling / speed
- direct connection between OPNsense<->AnyComputer
- switch in between
- auto-negotiated port speed (1G/2.5G)
- manually set fixed port speed (1G/2.5G)

Config
- any offloading disabled / enabled
- hw.igc.eee_setting disabled / enabled
- dev.igc.5.fc disabled / enabled
- net.inet.rss.enabled / disabled
- full sysctl see link below

Also, I have tried all other sorts of "somewhere recommended" tunables, just as shots in the dark.

Since I currently have no physical console access, I did not try modify BIOS settings yet. 

Trying to debug the issue for a few days now, there seem to be possible issues with the I225 / I226 chips. Others say they work perfect, also here in the forum.

Tests:

After some initial ookla speed tests on WAN, Iperf was used to do testing, both running against and through OPNsense. CPU is no limiting factor on either end. Besides the iperf test load, there was only some light additional load on the box.

Test results shown here are on igc5 connected at 1Gbit/s. As seen, errors only rise when OPNsense is receiving. Sending always gets full 1G speed without any errors. Multiple clients / switches testet.

- no errors shown on switch or remote side
- no other errors in OPNsense except for the "in errors"
- no VLAN involved
- interface IP OPNsense 192.168.96.1 on igc5

If anyone has more ideas on how to debug this issue, I would be glad for any further input. Any help is greatly appreciated. I will also post more of my own findings here in this thread.

I think I might have the same problem as you:

I have not found a solution yet

For I225 and I226, there are different variants (LM and V, e.g.) and there exists multiple hardware revisions which can be seen in the PCI IDs. There is a separate thread here covering this which you should refer to once you know exactly what your hardware revision (and counterpart) really is.

You should know that there have been multiple problems with the I225 and I226 depending on the counterpart of the connection. The first underlying problem was that Intel misinterpreted a specification for 2.5 GbE w/r to timing. The first fix was that the Intel drivers switched back to 1 GbE when they detected errors. They tried to solve this permanently with a V2 of the I225 (in vain), but apparently fixed it only in V3 and then decided to rename the chip to I226 because of the bad name the I225 had made. AFAIK, even that chips is now available in several revisions.

So, most of the I225 and I226 do not show any signs of a problem at all, while some people still have problems with certain counterparts.
