Hello,
I am running OpnSense on an Odroid H2.
I want to upgrade to an Odroid H2+ which has Realtek RTL8125B ethernets. On the Hardkernel wiki (https://wiki.odroid.com/odroid-h2/hardware/install_ethernet_driver_on_h2plus#downloadinstall_r8125_module) they explain how to compile it for Linux, but I have no idea on how to do it for OpnSense (FreeBSD).
Is it possible ? If so how to do it ?

Did you ever test this out?

No this does not work. Had it esxi and then shimmed in the realtek drivers (the old H model)- it just was buggy and dropped out frequently. Bare metal doesn't work at all with ubuntu, pfsense or opnsense.
as a win10 media box- it is wonderful, very fast, silent.
Super disappointed in Odroid for cheap'ing out and not getting intel nics. This would be a game changer if a box like this was out at around that pricepoint.
currently looking for a little box with ddr4 and a 6th gen intel cpu with a couple intel nics.
Thinking this;

Mini PC Q600S
Support Skylake-S and Kabylake-S FCLGA1151 desktop processor, dual Gigabit Intel network card, dual HDMI display, dual DDR4 memory,

...and that's why it is never going to happen. ;-)

Hi,
since opnsense version 20.7.4 - 2,5GB NIC drivers supported,
BUT to install you have to plugin a supported USB NIC, because the installer is still version 20.7 without 2,5GB NIC support.
With the USB NIC, you can upgrade to the current version and your H2+ 2,5GB NIC fully work.
My odroid H2+ opnsense build works without any issues in my case.
And a new 4 port network add-on card is out now.

i ordered one, delivery date is February.

Hi
How the CPU load looks like when these new "2.5Gbps RTL8125B ethernet" chips run with a high network throughput ?
Is it still very high (>50%) interrupt load on CPU ?
My experience is with many of the 1GbE Realteks, that they are simply not designed for throughput operation and when they are network-loaded they kill CPUs with interrupts (and as the result they are not recommended for serious projects ).
Thanks

Is this helpful ?
Scroll down a bit for there performance charts with 4 extra 2,5 realtec NICs

Yes, it is. Thanks
Not that it is clear how the depicted CPU load is distributed (e.g.: %usr, %sys, %interrupt....) but otherwise the graphs look as one would expect: 50% of the four cores of the CPU is busy with doing iperf3 (75% when reversed).
So it seems to me these new 8125's perform much better than those old 1Gigs.
If interested, see the attachment of a bad example: 2x iperf3 clients over two 1GbE links and 'top -P' (or 'top -1' , if Ubuntu) shows that both CPU cores are 50% busy with handling interrupts. And so there's not much of resources left for iperf and so this box with a two RTL8111 NICs simply does not perform.
This is, IMHO, the main reason why network appliances should avoid them.

For information, with the Odroid H2+; I have no issues with the upcoming 21.1 release. It works out-of-the-box.
Routing (ipv4-nat / ipv6) with RTL8125b's: 15.1% interrupts at 1gbit. 16% system load with shaping.

was digging around and found basically the same chipset/board but with Intel nics-

and the case is nicer.

Do you have the hardware acceleration active?
Do you use Vlans?
-
Here my Settings.

Here my Settings.
Thank you! I have the same settings. It's working flawlessly!
When I Change the settings in the first picture (removing the Checkmarks) then my Cablemodem goes nuts and restarts ist self.
So I assume Hardware acceleration isn't working with these NICs
