+# Intel i915-sriov-dkms and AMD MxGPU split a Physical Function (PF) into
+# multiple Virtual Functions (VFs). Switching the PF's driver destroys
+# every VF; switching a VF's driver affects only that VF. ProxMenux does
+# not yet manage the SR-IOV lifecycle (create/destroy VFs, track per-VF
+# ownership), so operating on a PF with active VFs — or on a VF itself —
+# would leave the user's virtualization stack in an inconsistent state.
+# We detect the situation early and hand the user back to the Proxmox
+# web UI, which understands VFs as first-class PCI devices.
