+Duplicate ACPI _SUN
+Description of problem:
+ACPI _SUN is `the slot-unique ID number for a slot`, but qemu uses `PCI_SLOT()` which is definitely not unique
+https://gitlab.com/qemu-project/qemu/-/blob/407f9a4b121eb65166375c410e14d7b704bc1106/hw/i386/acpi-build.c#L524
+Steps to reproduce:
+1. Create a linux VM with 2 virtio NICs
+2. Look at the ACPI _SUN of the virtio-pci devices (firmware_node/sun)
+
+Both virtio-pci devices have _SUN == 0
+```
+#
+Additional information:
+In systemd we recently introduced code to use firmware_node/sun information for NIC naming
+https://github.com/systemd/systemd/commit/0a4ecc54cb9f2d3418b970c51bfadb69c34ae9eb
+
+but having duplicate _SUN is of course problematic
