+.Sh DESCRIPTION
+The
+.Nm
+library contains
+.Xr bhyve 8
+code that is meant to be used by other userspace programs.
+Please refer to the
+.Xr bhyve_config 5
+manual page to read the documentation for the functions listed in
+.In bhyve/config.h .
+.Pp
+The
+.Fn netbe_legacy_config
+routine parses common network device backend options from the configuration
+string
+.Ar opt .
+.Pp
+The
+.Fn pci_init_fds
+routine creates all file descriptors required for a hotpluggable
+emulated PCI device
+.Ar devname
+and stores them in the
+.Ar nvl
+.Xr nvlist 9
+object.
+.Pp
+The
+.Fn pci_parse_config
+routine parses the configuration string
+.Ar config
+for a hotpluggable emulated PCI device specified by
+.Ar device
+using device-specific parsing routines.
+.Pp
+The
+.Fn pci_parse_legacy_config
+routine parses a list of "name[=value]" comma-separated options and stores them
+in the
+.Ar nvl
+.Xr nvlist 9
+object.
+.Pp
+The
+.Fn pci_validate_hotplug_request
+routine determines whether the
+.Ar nvl
+.Xr nvlist 9
+object contains all necessary name value pairs required for hotplugging an
+emulated PCI device specified by
+.Ar device .
