New error code on my ethernet connection?

TrueNAS General
1

I just upgraded to 25.10.1 and I see a new error code at the bottom of the dashboard:

TCP: enps05: Driver has suspect GRO implementation, TCP performance may be compromised

This is an Aquantia 10gbps copper interface and I don’t remember seeing this in the previous train. I’m not getting any manufacturer info from the various MAC lookup services, so who knows if the manufacturer is really real (00:e2:59:01:87:xx). It’s a cheap n100 power NAS board with dual nvme (single lane) and six SATA ports. A little detail here Mini Truenas server build. | ServeTheHome Forums But not much info on these devices due to where they are manufactured and sold.

You can try reading this other thread and checking with ethtool.

Similar thing on my end with my crappy Aquantia nic. Following as a post-init should clear you up.

ethtool -K #InterfaceNameHere# gro off

ethtool -K #InterfaceNameHere# lro off

Is ethtool install on the latest Truenas, or do I still need to install it? (yes I’m being lazy but at least I admit it).

I really wish they had used a better phy, and really wish they had used an SFP+ cage because I hate running twisted pair for this. A DAC or multimode fiber would be so much better, and so much cooler in my switch (my base-t module gets HOT). I have cable so not an issue, but the heat is kind of too much, or buy more expensive modules with newer chips that run cooler and farther. My distance is about 1 meter, maybe 2m if I route things in a longer and neater way.

NAS is in the silver chassis, the HP at the bottom are mostly taking up space, no UEFI so their value is quickly decreasing for everything I want to try and do, and the HP p420i is also giving me problems with newer Windows OS. Probably should sell off the DDR3 and recycle the rest.

Donno about newest as I’m too lazy to update & then deal with changes to SMART - but it is on whatever V i got in my signature.

sudo as necessary

As far as I can tell, ethtool has been part of TrueNAS SCALE since the very first release (Angelfish) 5 years ago.

Perhaps you are thinking about TrueNAS CORE?

Ok, that’s what I thought, but the link above mentioned needing to install it so it must have linked back to Core, I’m on Scale so should be good for me.
