FS 2.5GBase-T SFP not working with Turris Omnia

OK I finally got this working. This FS Generic Compatible 2.5GBASE-T SFP Copper RJ-45 module does indeed work: https://www.fs.com/products/139650.html

I dont know if it would have done it automatically or not but based on the comment above, I relinked the default device tree symlink and then rebooted and it worked without further changes to setup after that:

cd /boot/
rm dtb
ln -s armada-385-turris-omnia-sfp.dtb dtb

After reboot:
