# VirtIO support
+#
+# The virtio entry provides a generic bus for use by the device drivers.
+# It must be combined with an interface that communicates with the host.
+# Multiple such interfaces defined by the VirtIO specification. FreeBSD
+# only has support for PCI. Therefore, virtio_pci must be statically
+# compiled in or loaded as a module for the device drivers to function.
