Im sorry for maybe lame question, but Im starting with linux so have mercy.

I have Ryzen 2400G setup with ubuntu 18.04 and IOMMU turned on.
I added Intel Quad Port Gigabit Ethernet and I wanna use it on pfsense on KVM.

I saw a lot of posts etc about this issue but only with VGA pci-e cards and I cant make it work with my ethernet card.
If I understands it I need to unbind HW from driver and bind it to KVM.
But I dont know how to do it :(

Info about my ethernet controller:

Can someone please help to achieve what I want?
If you need any more info about my system etc, just ask.

Thanks for any suggestions and answers..

you can follow the Ubuntu Server Guide on this which has an example on vfio based passthrough. With that you do not need to unbind, but instead create virtual functions on your card and then forward these partitions of the card to your VMs. It also has an example on the libvirt xml fragments that you can either add to your guest xml directly or as a file on its own to be used by virsh attach-device ....

If instead you have no VF capable card you can still go with the unbinding of the device as you mentioned it. The forwarding part through libvirt looks just the same, but to unbinde you might take a look at examples of the linux-KVM wiki that uses the pci-stub.

If you don't want to use libvirt then linux-KVM wiki pci and linux-KVM wiki vfio also hold examples on the qemu commandline of this.
