Scale driver for RTL8126

TrueNAS General
1

Just got my 5Gbe Ethernet card that uses the rtl8126 chipset. It shows up when doing lspci but no driver loaded. Anyone know if it’s coming in later versions of Truenas Scale?

Did you manage to get it working?

Unfortunately no. The driver is included in later versions of the kernel, so here’s hoping it’s included in the next release.

25.04 is expected to ship a newer LTS kernel (probably 6.12?). BETA for that in Feb~ timeframe.

I got this working. It took me a few hours, but I did it. Still working out the kinks, iperf3 has me at 3.32gb transfer speeds. Pretty sure its my cable or my SFP adapter, I will do more testing.

enable developer mode:
sudo /usr/local/libexec/disable-rootfs-protection
(You cant undo this)

unmount/remount:
mount -o remount,rw ‘boot-pool/ROOT/24.04.0/usr’
(Make sure you use the version you have installed, I had to use 24.04.2.2)

Then you do this:
export PATH=/usr/bin:/usr/sbin

And then you do this:
chmod +x /bin/apt*
chmod +x /usr/bin/dpkg

Then you download the realtek driver (Realtek’s website has a dumb download, I downloaded the file, uploaded it to a free filehost, then used wget to download it to my TrueNAS install)

Then I unpacked the tar.bz2 file

Then I ran the autorun.sh with Bash
bash -x ./autorun.sh

Rebooted, and it worked fine.

Hope this helps. I literally created an account on the forum to share this.

Thanks for posting a solution.

I tried but when i run the autorun.sh it start but the system crashes. It displays this before the crash:
