After upgrade from 25.1.12 to 25.7.2: High response times when having traffic

[rainerle]

Hi,
after the upgrade on Tuesday the uplink delay went up from 1.2ms to 24ms.

Where can I look to fix this?

The measurement is taken from another machine behind the opnsense.

CPU usage between 2% and 12%,
More than 50% Memory free,
no idea where to look further...

Thanks
Rainer

Your x722 is many/few revs behind.
You are currently at NVM 4.00 (software 23.4 or 23.5.2), which is just about dead middle of the Intel versions available.

The latest for x722 is from software 30.1.0.1 with NVM 6.50

Matrix here --> https://cdrdv2.intel.com/v1/dl/getContent/336882

In the features matrix you can see there's not much new from old stuff to new, mostly virtualization stuff. Well, it doesn't actually says if any issues for any feature was fixed, it's just a feature matrix, etc.

Here's the crux, Intel revision 3.5 is dated June 3 2025, freeBSD v14.3 release is dated June 10 2025, the Intel doc does not list freeBSD v14.3 as supported, but shows 14.1 for latest v14.x. EDIT: see below for the 30.4 Intel release info.

My guess is, the ixl kernel driver in freeBSD 14.3 should be ok, but it appears to not be validated by Intel (see notes about 30.4)
Upgrading NVM would be for two reasons:
1) needing a newer feature
2) possibly fixing issues (of which is not mentioned in the Intel doc)

For best possible function with less probability for errors, make sure the sfp's are "Intel validated".
See the bsd doc for ethernet/driver support --> https://www.freebsd.org/releases/14.3R/hardware/#ethernet

Since the bsd 14.3 doc does say ixl supports Intel 700 series, I think it's ok as long as the SFP's are Intel type, which your outputs appear to show.

The only caveat is, where did you get those Intel SFP's? Years ago I had issue with cisco switch gear that only played nice with real cisco SFP's, and the ones we got reported as "cisco" but were actual grayware that got into supply chain. Vendor got us new SFP's from another supply chain line and then all was good. This however was just turning up the SFP in a specific fiber mode.

All that said, the only eye-catcher is that the Intel doc does not list freeBSD v14.3 as supported, but the bsd docs seems to say ixl is good to go.
Is there something in the 14.3 ixl driver that is not playing nice with your older NVM? Possibly so. There's no matrix I can find that does back-versioning validation.

EDIT: So if you select latest release 30.4 and hit DOWNLOAD button (https://www.intel.com/content/www/us/en/content-details/778690/intel-ethernet-controller-products-release-notes.html) you get the 30.4 release notes, it lists 700 series and freeBSD 14.3 as supported. However, I downloaded the 30.4 bundle (900MB zip file) and I don't see x722 in it.

Note: The 30.4 doc mentions 700 series, no new NVM. NVM 6.5 is the latest and from what I can see, no changes to x722 between 30.1.0.1 and 30.4, other than 30.4 says freeBSD 14.3 is supported:

2.2 Intel® Ethernet 700 Series Network Adapters
     2.2.1 Firmware/NVM/NVM Update
          • None in this release

Note: The only "known issues" I see are notes around the 710, nothing for the x722.

Another oddity is, Intel docs are not 100%. Release notes list x722 as being in the Intel 30.1.0.1 download bundle, but when I open that bundle I don't find x722, I only see the 710 for 700 series.

bsd 14.3 reference: https://www.freebsd.org/releases/14.3R/announce/

Intel
https://www.intel.com/content/www/us/en/content-details/853125/intel-ethernet-controller-products-release-notes.html
30.1.0.1 bundle --> https://downloadmirror.intel.com/856143/Release__30.1.0.1.zip
30.4 bundle --> https://downloadmirror.intel.com/863589/Release_30.4.zip

Neither bundle has any x722 stuff, just 710. Makes me wonder if x722 is an integrator only item?

Also, Intel device ID 0x37d3 (dec 170) I can't find just yet. It's reporting vendor=0x8086 which is ID for Intel.
