igb-interface temporarily down since 23.1

[8b4df00d]

Hi,

my opnsense build uses a quad-port nic with igb-drivers for lan-communication, bundled with lacp. When i installed the card like 2 years ago i've had the problem that all ports went down after like 2 days and they stayed down till i rebooted the firewall, set the interface down and up or remove the network cables.

To fix that problem, i simply put the following tunables into my system:
dev.igb.0.eee_disabled = 1
dev.igb.1.eee_disabled = 1
dev.igb.2.eee_disabled = 1
dev.igb.3.eee_disabled = 1

After my upgrade to 23.1 these tunables are shown as unsupported and my nic started to have the problems mentioned above again. After a quick google search i found that people suggested to simply remove these and the nic should working again. But in my case the problem still exists. All ports an so my lacp is going down after like 2 days in use.

Does anyone have the same problem and maybe also a fix for this?

Thanks.

Hi,

my problem mentioned above is now fixed. Here's the issue:
First of all, my problems with my LACP going down after 2 days was fixed by removing the tunables dev.igb.0.eee_disabled = 1 etc.

But after removing those tunables i had weird flapping issues on devices that are routed over that dynamic trunk. Because the issues with my NIC happened after updating to 23.1, i focused on a software/hardware problem.

So i changed my NIC to an identical one, rebooted my switch, changed switch-ports... no changes, devices still flapping.

Yesterday i thought, lets give another network cable a try... boom, problem fixed  ::)


So in other words, no problem with igb-drivers on OPNsense.

As always, i want so say thank you for providing such an amazing firewall :)

Bye.

dev.igb.0.eee_disabled = 1
dev.igb.1.eee_disabled = 1
dev.igb.2.eee_disabled = 1
dev.igb.3.eee_disabled = 1

After my upgrade to 23.1 these tunables are shown as unsupported

In case anyone else stumbles across this...
The driver tunable used to be (assuming igb0 interface):

dev.igb.0.eee_disabled
You now have to use:
