Which PCI Device for NIC

[nomadix]

Hello,

I'm trying to figure out which if my onboard NICs corresponds to which PCI device so I can pass one through to a Truenas VM. I have four onboard NICs that each appear to have their own IOMMU group. I can't seem to figure out which NIC is which PCI device, as I'm not sure where else to look. Is there another command I can use to find this information?

Wait...is it really as simple as this? I just noticed this pattern...

enp6s0 -> 06:00.0
enp7s0 -> 07:00.0
enp10s0 -> 0a:00.0
enp11s0 -> 0b:00.0
