-.Sh DESCRIPTION
-The
-.Nm libnv
-library allows to easily manage name value pairs as well as send and receive
-them over sockets.
-A group (list) of name value pairs is called an
-.Nm nvlist .
-The API supports the following data types:
-.Bl -ohang -offset indent
-.It Sy null ( NV_TYPE_NULL )
-There is no data associated with the name.
-.It Sy bool ( NV_TYPE_BOOL )
-The value can be either
-.Dv true
-or
-.Dv false .
-.It Sy number ( NV_TYPE_NUMBER )
-The value is a number stored as
-.Vt uint64_t .
-.It Sy string ( NV_TYPE_STRING )
-The value is a C string.
-.It Sy nvlist ( NV_TYPE_NVLIST )
-The value is a nested nvlist.
-.It Sy descriptor ( NV_TYPE_DESCRIPTOR )
-The value is a file descriptor.
-Note that file descriptors can be sent only over
-.Xr unix 4
-domain sockets.
-.It Sy binary ( NV_TYPE_BINARY )
-The value is a binary buffer.
-.El
-.Pp
-The
-.Fn nvlist_create
-function allocates memory and initializes an nvlist.
-.Pp
-The following flag can be provided:
-.Pp
-.Bl -tag -width "NV_FLAG_IGNORE_CASE" -compact -offset indent
-.It Dv NV_FLAG_IGNORE_CASE
-Perform case-insensitive lookups of provided names.
-.El
-.Pp
-The
-.Fn nvlist_destroy
-function destroys the given nvlist.
-Function does nothing if
-.Dv NULL
-nvlist is provided.
-Function never modifies the
-.Va errno
-global variable.
-.Pp
-The
-.Fn nvlist_error
-function returns any error value that the nvlist accumulated.
-If the given nvlist is
-.Dv NULL
-the
-.Er ENOMEM
-error will be returned.
-.Pp
-The
-.Fn nvlist_set_error
-function sets an nvlist to be in the error state.
-Subsequent calls to
-.Fn nvlist_error
-will return the given error value.
-This function cannot be used to clear the error state from an nvlist.
-This function does nothing if the nvlist is already in the error state.
-.Pp
-The
-.Fn nvlist_empty
-function returns
-.Dv true
-if the given nvlist is empty and
-.Dv false
-otherwise.
-The nvlist must not be in error state.
-.Pp
-The
-.Fn nvlist_flags
-function returns flags used to create the nvlist with the
-.Fn nvlist_create
-function.
-.Pp
-The
-.Fn nvlist_clone
-functions clones the given nvlist.
-The clone shares no resources with its origin.
-This also means that all file descriptors that are part of the nvlist will be
-duplicated with the
-.Xr dup 2
-system call before placing them in the clone.
-.Pp
-The
-.Fn nvlist_dump
-dumps nvlist content for debugging purposes to the given file descriptor
-.Fa fd .
-.Pp
-The
-.Fn nvlist_fdump
-dumps nvlist content for debugging purposes to the given file stream
-.Fa fp .
-.Pp
-The
-.Fn nvlist_size
-function returns the size of the given nvlist after converting it to binary
-buffer with the
-.Fn nvlist_pack
-function.
-.Pp
-The
-.Fn nvlist_pack
-function converts the given nvlist to a binary buffer.
-The function allocates memory for the buffer, which should be freed with the
-.Xr free 3
-function.
-If the
-.Fa sizep
-argument is not
-.Dv NULL ,
-the size of the buffer will be stored there.
-The function returns
-.Dv NULL
-in case of an error (allocation failure).
-If the nvlist contains any file descriptors
-.Dv NULL
-will be returned.
-The nvlist must not be in error state.
-.Pp
-The
-.Fn nvlist_unpack
-function converts the given buffer to the nvlist.
-The function returns
-.Dv NULL
-in case of an error.
-.Pp
-The
-.Fn nvlist_send
-function sends the given nvlist over the socket given by the
-.Fa sock
-argument.
-Note that nvlist that contains file descriptors can only be send over
-.Xr unix 4
-domain sockets.
-.Pp
-The
-.Fn nvlist_recv
-function receives nvlist over the socket given by the
-.Fa sock
-argument.
-.Pp
-The
-.Fn nvlist_xfer
-function sends the given nvlist over the socket given by the
-.Fa sock
-argument and receives nvlist over the same socket.
-The given nvlist is always destroyed.
-.Pp
-The
-.Fn nvlist_next
-function iterates over the given nvlist returning names and types of subsequent
-elements.
-The
-.Fa cookiep
-argument allows the function to figure out which element should be returned
-next.
-The
-.Va *cookiep
-should be set to
-.Dv NULL
-for the first call and should not be changed later.
-Returning
-.Dv NULL
-means there are no more elements on the nvlist.
-The
-.Fa typep
-argument can be NULL.
-Elements may not be removed from the nvlist while traversing it.
-The nvlist must not be in error state.
-.Pp
-The
-.Fn nvlist_exists
-function returns
-.Dv true
-if element of the given name exists (besides of its type) or
-.Dv false
-otherwise.
-The nvlist must not be in error state.
-.Pp
-The
-.Fn nvlist_exists_type
-function returns
-.Dv true
-if element of the given name and the given type exists or
-.Dv false
-otherwise.
-The nvlist must not be in error state.
-.Pp

-.Fn nvlist_exists_null ,
-.Fn nvlist_exists_bool ,
-.Fn nvlist_exists_number ,
-.Fn nvlist_exists_string ,
-.Fn nvlist_exists_nvlist ,
-.Fn nvlist_exists_descriptor ,
-.Fn nvlist_exists_binary
-functions return
-.Dv true
-if element of the given name and the given type determined by the function name

-.Fn nvlist_add_descriptor ,
-.Fn nvlist_add_binary
-functions add element to the given nvlist.
-When adding string or binary buffor the functions will allocate memory
-and copy the data over.
-When adding nvlist, the nvlist will be cloned and clone will be added.
-When adding descriptor, the descriptor will be duplicated using the
-.Xr dup 2
-system call and the new descriptor will be added.
-If an error occurs while adding new element, internal error is set which can be
-examined using the
-.Fn nvlist_error
-function.

-The
-.Fn nvlist_move_string ,
-.Fn nvlist_move_nvlist ,

-functions allow to obtain value of the given name.
-In case of string, nvlist, descriptor or binary, returned resource should
-not be modified - it still belongs to the nvlist.
-If element of the given name does not exist, the program will be aborted.
-To avoid that the caller should check for existence before trying to obtain
-the value or use
-.Xr dnvlist 3
-extension, which allows to provide default value for a missing element.
-The nvlist must not be in error state.

-functions return value associated with the given name and remove the element
-from the nvlist.
-In case of string and binary values, the caller is responsible for free returned
-memory using the
-.Xr free 3
-function.
-In case of nvlist, the caller is responsible for destroying returned nvlist
-using the

+.Os
+.Sh NAME
+.Nm PCI_IOV_ADD_VF
+.Nd inform a PF driver that a VF is being created
+.Sh SYNOPSIS
+.In sys/bus.h
+.In machine/stdarg.h
+.In sys/nv.h
+.In dev/pci/pci_iov.h
+.Ft int
+.Fn PCI_IOV_ADD_VF "device_t dev" "uint16_t vfnum" "const nvlist_t *vf_config"
+.Sh DESCRIPTION
+The
+.Fn PCI_IOV_ADD_VF
+method is called by the PCI Single-Root I/O Virtualization
+.Pq SR-IOV
+infrastructure when it is initializating a new Virtual Function (VF) as a child
+of the given Physical Function (PF) device.
+This method will not be called until a successful call to
+.Xr PCI_IOV_INIT 9
+has been made.
+It is not guaranteed that this method will be called following a successful call
+to
+.Xr PCI_IOV_INIT 9 .
+If the infrastructure encounters a failure to allocate resources following the
+call to
+.Xr PCI_IOV_INIT 9 ,
+the VF creation will be aborted and
+.Xr PCI_IOV_UNINIT 9
+will be called immediately without any preceding calls to
+.Nm .
+.Pp
+The index of the VF being initialized is passed in the
+.Fa vfnum
+argument.
+VFs are always numbered sequentially starting at 0.
+.Pp
+If the driver requested device-specific configuration parameters via a VF schema
+in its call to
+.Xr pci_iov_attach 9 ,
+those parameters will be contained in the
+.Pa vf_config
+argument.
+All configuration parameters that were either set as required parameters or that
+had a default value set in the VF schema are guaranteed to be present in
+.Fa vf_config .
+Configuration parameters that were neither set as required nor were given a
+default value are optional and may or may not be present in
+.Fa vf_config .
+.Fa vf_config
+will not contain any configuration parameters that were not specified in the VF
+schema.
+All configuration parameters will have the correct type and will be in the range
+of valid values specified in the schema.
+.Pp
+Note that it is possible for the user to set different configuration values on
+different VF devices that are children of the same PF.
+The PF driver must not cache configuration parameters passed in previous calls

+.Fn PCI_IOV_INIT "device_t dev" "uint16_t num_vfs" "const nvlist_t *pf_config"
+.Sh DESCRIPTION
+The
+.Fn PCI_IOV_INIT
+method is called by the PCI Single-Root I/O Virtualization (SR-IOV)
+infrastucture when the user requests that SR-IOV be enabled on a Physical
+Function (PF).
+The number of Virtual Functions (VFs) that will be created is passed to this
+method in the
+.Fa num_vfs
+argument.
+.Pp
+If the driver requested device-specific PF configuration parameters via a PF
+schema in its call to
+.Xr pci_iov_attach 9 ,
+those parameters will be available in the
+.Fa pf_config
+argument.
+All configuration parameters that were either set as required parameters or that
+had a default value set in the PF schema are guaranteed to be present in
+.Fa pf_config .
+Configuration parameters that were neither set as required nor were given a
+default value are optional and may or may not be present in
+.Fa pf_config .
+.Fa pf_config
+will not contain any configuration parameters that were not specified in the PF
+schema.
+All configuration parameters will have the correct type and are in the range of
+valid values specified in the schema.
+.Pp
+If this method returns successfully, then this method will not be called again
+on the same device until after a call to
+.Xr PCI_IOV_UNINIT .
+.Sh RETURN VALUES
+Returns 0 on success, otherwise an appropriate error is returned.
+If this method returns an error then the SR-IOV configuration will be aborted
+and no VFs will be created.

+.Sh DESCRIPTION
+The
+.Nm libnv
+library allows to easily manage name value pairs as well as send and receive
+them over sockets.
+A group (list) of name value pairs is called an
+.Nm nvlist .
+The API supports the following data types:
+.Bl -ohang -offset indent
+.It Sy null ( NV_TYPE_NULL )
+There is no data associated with the name.
+.It Sy bool ( NV_TYPE_BOOL )
+The value can be either
+.Dv true
+or
+.Dv false .
+.It Sy number ( NV_TYPE_NUMBER )
+The value is a number stored as
+.Vt uint64_t .
+.It Sy string ( NV_TYPE_STRING )
+The value is a C string.
+.It Sy nvlist ( NV_TYPE_NVLIST )
+The value is a nested nvlist.
+.It Sy descriptor ( NV_TYPE_DESCRIPTOR )
+The value is a file descriptor.
+Note that file descriptors can be sent only over
+.Xr unix 4
+domain sockets.
+.It Sy binary ( NV_TYPE_BINARY )
+The value is a binary buffer.
+.It Sy bool array ( NV_TYPE_BOOL_ARRAY )
+The value is an array of boolean values.
+.It Sy number array ( NV_TYPE_NUMBER_ARRAY )
+The value is an array of numbers, each stored as
+.Vt uint64_t .
+.It Sy string array ( NV_TYPE_STRING_ARRAY )
+The value is an array of C strings.
+.It Sy nvlist array ( NV_TYPE_NVLIST_ARRAY )
+The value is an array of nvlists.
+When an nvlist is added to an array, it becomes part of the primary nvlist.
+Traversing these arrays can be done using the
+.Fn nvlist_get_array_next
+and
+.Fn nvlist_get_pararr
+functions.
+.It Sy descriptor array ( NV_TYPE_DESCRIPTOR_ARRAY )
+The value is an array of files descriptors.
+.El
+.Pp
+The
+.Fn nvlist_create
+function allocates memory and initializes an nvlist.
+.Pp
+The following flag can be provided:
+.Pp
+.Bl -tag -width "NV_FLAG_IGNORE_CASE" -compact -offset indent
+.It Dv NV_FLAG_IGNORE_CASE
+Perform case-insensitive lookups of provided names.
+.It Dv NV_FLAG_NO_UNIQUE
+Names in the nvlist do not have to be unique.
+.El
+.Pp
+The
+.Fn nvlist_destroy
+function destroys the given nvlist.
+Function does nothing if
+.Dv NULL
+nvlist is provided.
+Function never modifies the
+.Va errno
+global variable.
+.Pp
+The
+.Fn nvlist_error
+function returns any error value that the nvlist accumulated.
+If the given nvlist is
+.Dv NULL
+the
+.Er ENOMEM
+error will be returned.
+.Pp
+The
+.Fn nvlist_set_error
+function sets an nvlist to be in the error state.
+Subsequent calls to
+.Fn nvlist_error
+will return the given error value.
+This function cannot be used to clear the error state from an nvlist.
+This function does nothing if the nvlist is already in the error state.
+.Pp
+The
+.Fn nvlist_empty
+function returns
+.Dv true
+if the given nvlist is empty and
+.Dv false
+otherwise.
+The nvlist must not be in error state.
+.Pp
+The
+.Fn nvlist_flags
+function returns flags used to create the nvlist with the
+.Fn nvlist_create
+function.
+.Pp
+The
+.Fn nvlist_in_array
+function returns
+.Dv true
+if
+.Fa nvl
+is part of an array that is a member of another nvlist.
+.Pp
+The
+.Fn nvlist_clone
+functions clones the given nvlist.
+The clone shares no resources with its origin.
+This also means that all file descriptors that are part of the nvlist will be
+duplicated with the
+.Xr dup 2
+system call before placing them in the clone.
+.Pp
+The
+.Fn nvlist_dump
+dumps nvlist content for debugging purposes to the given file descriptor
+.Fa fd .
+.Pp
+The
+.Fn nvlist_fdump
+dumps nvlist content for debugging purposes to the given file stream
+.Fa fp .
+.Pp
+The
+.Fn nvlist_size
+function returns the size of the given nvlist after converting it to binary
+buffer with the
+.Fn nvlist_pack
+function.
+.Pp
+The
+.Fn nvlist_pack
+function converts the given nvlist to a binary buffer.
+The function allocates memory for the buffer, which should be freed with the
+.Xr free 3
+function.
+If the
+.Fa sizep
+argument is not
+.Dv NULL ,
+the size of the buffer will be stored there.
+The function returns
+.Dv NULL
+in case of an error (allocation failure).
+If the nvlist contains any file descriptors
+.Dv NULL
+will be returned.
+The nvlist must not be in error state.
+.Pp
+The
+.Fn nvlist_unpack
+function converts the given buffer to the nvlist.
+The
+.Fa flags
+argument defines what type of the top level nvlist is expected to be.
+Flags are set up using the
+.Fn nvlist_create
+function.
+If the nvlist flags do not match the flags passed to
+.Fn nvlist_unpack ,
+the nvlist will not be returned.
+Every nested nvlist list should be checked using
+.Fn nvlist_flags
+function.
+The function returns
+.Dv NULL
+in case of an error.
+.Pp
+The
+.Fn nvlist_send
+function sends the given nvlist over the socket given by the
+.Fa sock
+argument.
+Note that nvlist that contains file descriptors can only be send over
+.Xr unix 4
+domain sockets.
+.Pp
+The
+.Fn nvlist_recv
+function receives nvlist over the socket given by the
+.Fa sock
+argument.
+The
+.Fa flags
+argument defines what type of the top level nvlist is expected to be.
+Flags are set up using the
+.Fn nvlist_create
+function.
+If the nvlist flags do not match the flags passed to
+.Fn nvlist_recv ,
+the nvlist will not be returned.
+Every nested nvlist list should be checked using
+.Fn nvlist_flags
+function.
+.Pp
+The
+.Fn nvlist_xfer
+function sends the given nvlist over the socket given by the
+.Fa sock
+argument and receives nvlist over the same socket.
+The
+.Fa flags
+argument defines what type of the top level nvlist is expected to be.
+Flags are set up using the
+.Fn nvlist_create
+function.
+If the nvlist flags do not match the flags passed to

+.Pp
+The

+function iterates over the given nvlist returning names and types of subsequent

+argument allows the function to figure out which element should be returned
+next.
+The
+.Va *cookiep
+should be set to

+for the first call and should not be changed later.
+Returning
+.Dv NULL
+means there are no more elements on the nvlist.
+The

+argument can be NULL.
+Elements may not be removed from the nvlist while traversing it.
+The nvlist must not be in error state.
+Note that
+.Fn nvlist_next
+will handle

+.Sh DESCRIPTION
+The PCI Single-Root I/O Virtualization
+.Pq SR-IOV
+configuration schema is a data
+structure that describes the device-specific configuration parameters that a PF
+driver will accept when SR-IOV is enabled on the PF device.
+Each PF driver defines two schema instances: the PF schema and the VF schema.
+The PF schema describes configuration that applies to the PF device as a whole.
+The VF schema describes configuration that applies to an individual VF device.
+Different VF devices may have different configuration applied to them, as long
+as the configuration for each VF conforms to the VF schema.
+.Pp
+A PF driver builds a configuration schema by first allocating a schema node and
+then adding configuration parameter specifications to the schema.
+The configuration parameter specification consists of a name and a value type.
+.Pp
+Configuration parameter names are case-insensitive.
+It is an error to specify two or more configuration parameters with the same
+name.
+It is also an error to specific a configuration parameter that uses the same
+name as a configuration parameter used by the SR-IOV infrastructure.
+See
+.Xr iovctl.conf 5
+for documentation of all configuration parameters used by the SR-IOV
+infrastructure.
+.Pp
+The parameter type constrains the possible values that the configuration
+parameter may take.
+.Pp
+A configuration parameter may be specified as a required parameter by setting
+the
+.Dv IOV_SCHEMA_REQUIRED
+flag in the
+.Pa flags
+argument.
+Required parameters must be specified by the user when SR-IOV is enabled.
+If the user does not specify a required parameter, the SR-IOV infrastructure
+will abort the request to enable SR-IOV and return an error to the user.
+.Pp
+Alternatively, a configuration parameter may be given a default value by
+setting the
+.Dv IOV_SCHEMA_HASDEFAULT
+flag in the
+.Pa flags
+argument.
+If a configuration parameter has a default value but the user has not specified
+a value for that parameter, then the SR-IOV infrastructure will apply
+.Pa defaultVal
+for that parameter in the configuration before passing it to the PF driver.
+It is an error for the value of the
+.Pa defaultVal
+parameter to not conform to the restrictions of the specified type.
+If this flag is not specified then the
+.Pa defaultVal
+argument is ignored.
+This flag is not compatible with the
+.Dv IOV_SCHEMA_REQUIRED
+flag; it is an error to specify both on the same parameter.
+.Pp
+The SR-IOV infrastructure guarantees that all configuration parameters that are
+either specified as required or given a default value will be present in the
+configuration passed to the PF driver.
+Configuration parameters that are neither specified as required nor given a
+default value are optional and may or may not be present in the configuration
+passed to the PF driver.
+.Pp
+It is highly recommended that a PF driver reserve the use of optional parameters
+for configuration that is truly optional.
+For example, a Network Interface PF device might have the option to encapsulate
+all traffic to and from a VF device in a vlan tag.
+The PF driver could expose that option as a "vlan" parameter accepting an
+integer argument specifying the vlan tag.
+In this case, it would be appropriate to set the "vlan" parameter as an optional
+parameter as it would be legitimate for a VF to be configured to have no vlan
+tagging enabled at all.
+.Pp
+Alternatively, if the PF device had an boolean option that controlled whether
+the VF was allowed to change its MAC address, it would not be appropriate to
+set this parameter as optional.
+The PF driver must either allow the MAC to change or not, so it would be more
+appropriate for the PF driver to document the default behaviour by specifying
+a default value in the schema
+.Po or potentially force the user to make the choice by setting the parameter
+to be required
+.Pc .
+.Pp
+Configuration parameters that have security implications must default to the
+most secure configuration possible.
+.Pp
+All device-specific configuration parameters must be documented in the manual
+page for the PF driver, or in a separate manual page that is cross-referenced
+from the main driver manual page.
+.Pp
+It is not necessary for a PF driver to check for failure from any of these
+functions.
+If an error occurs, it is flagged in the schema.
+The
+.Xr pci_iov_attach 9
+function checks for this error and will fail to initialize SR-IOV on the PF
+device if an error is set in the schema.
+If this occurs, it is recommended that the PF driver still succeed in attaching
+and run with SR-IOV disabled on the device.
+.Pp
+The
+.Fn pci_iov_schema_alloc_node
+function is used to allocate an empty configuration schema.
+It is not necessary to check for failure from this function.
+The SR-IOV infrastructure will gracefully handle failure to allocate a schema
+and will simply not enable SR-IOV on the PF device.
+.Pp
+The
+.Fn pci_iov_schema_add_bool
+function is used to specify a configuration parameter in the given schema with
+the name
+.Pa name
+and having a boolean type.
+Boolean values can only take the value true or false (1 or 0, respectively).
+.Pp
+The
+.Fn pci_iov_schema_add_string
+function is used to specify a configuration parameter in the given schema with
+the name
+.Pa name
+and having a string type.
+String values are standard C strings.
+.Pp
+The

+ * Because each PF device is expected to expose a unique set of possible

+ * schema.
+ * 3) All keys are mandatory unless explicitly documented as optional. If a
+ * key is mandatory then the associated value is also mandatory.
+ * 4) Order of keys is irrelevant.
+ *
+ * TOP LEVEL
+ * 1) There must be a top-level key with the name PF_CONFIG_NAME. The value
+ * associated with this key is a nvlist that follows the device schema
+ * node format. The parameters in this node specify the configuration
+ * parameters that may be applied to a PF.
+ * 2) There must be a top-level key with the name VF_SCHEMA_NAME. The value
+ * associated with this key is a nvlist that follows the device schema
+ * node format. The parameters in this node specify the configuration
+ * parameters that may be applied to a VF.
+ *
+ * DEVICE SCHEMA NODE
+ * 1) There must be a key with the name DRIVER_CONFIG_NAME. The value
+ * associated with this key is a nvlist that follows the device/subsystem
+ * schema node format. The parameters in this node specify the
+ * configuration parameters that are specific to a particular device
+ * driver.
+ * 2) There must be a key with the name IOV_CONFIG_NAME. The value associated
+ * with this key is an nvlist that follows the device/subsystem schema node
+ * format. The parameters in this node specify the configuration
+ * parameters that are applied by the SR-IOV infrastructure.
+ *
+ * DEVICE/SUBSYSTEM SCHEMA NODE
+ * 1) All keys in the device/subsystem schema node are optional.
+ * 2) Each key specifies the name of a valid configuration parameter that may
+ * be applied to the device/subsystem combination specified by this node.
+ * The value associated with the key specifies the format of valid
+ * configuration values, and must be a nvlist in parameter schema node
+ * format.
+ *
+ * PARAMETER SCHEMA NODE
+ * 1) The parameter schema node must contain a key with the name
+ * TYPE_SCHEMA_NAME. The value associated with this key must be a string.
+ * This string specifies the type of value that the parameter specified by
+ * this node must take. The string must have one of the following values:
+ * - "bool" - The configuration value must be a boolean.
+ * - "mac-addr" - The configuration value must be a binary value. In
+ * addition, the value must be exactly 6 bytes long and
+ * the value must not be a multicast or broadcast mac.
+ * - "uint8_t" - The configuration value must be a integer value in
+ * the range [0, UINT8_MAX].
+ * - "uint16_t" - The configuration value must be a integer value in
+ * the range [0, UINT16_MAX].
+ * - "uint32_t" - The configuration value must be a integer value in
+ * the range [0, UINT32_MAX].
+ * - "uint64_t" - The configuration value must be a integer value in
+ * the range [0, UINT64_MAX].
+ * 2) The parameter schema may contain a key with the name
+ * REQUIRED_SCHEMA_NAME. This key is optional. If this key is present, the
+ * value associated with it must have a boolean type. If the value is true,
+ * then the parameter specified by this schema is a required parameter. All
+ * valid configurations must include all required parameters.
+ * 3) The parameter schema may contain a key with the name DEFAULT_SCHEMA_NAME.
+ * This key is optional. This key must not be present if the parameter
+ * specified by this schema is required. If this key is present, the value
+ * associated with the parent key must follow all restrictions specified by
+ * the type specified by this schema. If a configuration does not supply a
+ * value for the parameter specified by this schema, then the kernel will
+ * apply the value associated with this key in its place.
+ *
+ * The following is an example of a valid schema, as printed by nvlist_dump.
+ * Keys are printed followed by the type of the value in parantheses. The
+ * value is displayed following a colon. The indentation level reflects the
+ * level of nesting of nvlists. String values are displayed between []
+ * brackets. Binary values are shown with the length of the binary value (in

+ * 3) Unless otherwise specified, all keys are optional. It should go without

+ * specified to contain a sub-nodes that contains a mandatory key, then
+ * the outer key is implicitly mandatory. If a key is mandatory then the
+ * associated value is also mandatory.
+ * 4) Order of keys is irrelevant.
+ *
+ * TOP LEVEL OF CONFIG NVLIST
+ * 1) All keys specified in this section are mandatory.
+ * 2) There must be a top-level key with the name PF_CONFIG_NAME. The value
+ * associated is an nvlist that follows the "device node" format. The
+ * parameters in this node specify parameters that apply to the PF.
+ * 3) For every VF being configured (this is set via the "num_vfs" parameter
+ * in the PF section), there must be a top-level key whose name is VF_PREFIX
+ * immediately followed by the index of the VF as a decimal integer. For
+ * example, this would be VF-0 for the first VF. VFs are numbered starting
+ * from 0. The value associated with this key follows the "device node"
+ * format. The parameters in this node specify configuration that applies
+ * to the VF specified in the key. Leading zeros are not permitted in VF
+ * index. Configuration for the second VF must be specified in a node with
+ * the key VF-1. VF-01 is not a valid key.
+ *
+ * DEVICE NODES
+ * 1) All keys specified in this section are mandatory.
+ * 2) The device node must contain a key with the name DRIVER_CONFIG_NAME. The
+ * value associated with this key is an nvlist following the subsystem node
+ * format. The parameters in this key specify configuration that is specific
+ * to a particular device driver.
+ * 3) The device node must contain a key with the name IOV_CONFIG_NAME. The
+ * value associated with this key is an nvlist following the subsystem node
+ * format. The parameters in this key specify configuration that is consumed
+ * by the SR-IOV infrastructure.
+ *
+ * SUBSYSTEM NODES
+ * 1) A subsystem node specifies configuration parameters that apply to a
+ * particular subsystem (driver or infrastructure) of a particular device
+ * (PF or individual VF).
+ * Note: We will refer to the section of the configuration schema that
+ * specifies the parameters for this subsystem and device
+ * configuration as the device/subystem schema.
+ * 2) The subsystem node must contain only keys that correspond to parameters
+ * that are specified in the device/subsystem schema.
+ * 3) Every parameter specified as required in the device/subsystem schema is
+ * a mandatory key in the subsystem node.
+ * Note: All parameters that are not required in device/subsystem schema are
+ * optional keys. In particular, any parameter specified to have a
+ * default value in the device/subsystem schema is optional. The
+ * kernel is responsible for applying default values.
+ * 4) The value of every parameter in the device node must conform to the
+ * restrictions of the type specified for that parameter in the device/
+ * subsystem schema.
+ *
+ * The following is an example of a valid configuration, when validated against
+ * the schema example given above.
+ *

+.Op Fl n
+.Nm
+.Fl D
+.Op Fl f Ar config-file | Fl d Ar device
+.Op Fl n
+.Nm
+.Fl S
+.Op Fl f Ar config-file | Fl d Ar device
+.Sh DESCRIPTION
+The
+.Nm
+utility creates or destroys PCI Single-Root I/O Virtualization
+.Pq SR-IOV
+Virtual Functions
+.Pq VFs .
+When invoked with the
+.Fl C
+flag,
+.Nm
+creates VFs as children of the Physical Function
+.Pq PF
+configured in the specified configuration file.
+When invoked with the
+.Fl D
+flag,
+.Nm
+destroys all VFs that are children of the specified device.
+Available PF devices can be seen in
+.Pa /dev/iov/ .
+.Pp
+The following options are available:
+.Bl -tag -width indent
+.It Fl C
+Enable SR-IOV on the specified PF device and create VF children.
+This operation will fail if the PF already has VF children.
+This option must be used in conjunction with the
+.Fl f
+option.
+.It Fl d Ar device
+Specify the PF device to use for the given operation.
+.Ar device
+may either be the name of a PF device, or a full path name to a node in
+.Pa /dev/iov/ .
+This option may not be used with the
+.Fl C
+option.
+.It Fl D
+Delete all VF children of the specified PF device.
+This operation will fail if SR-IOV is not currently enabled on the specified
+device.
+.It Fl f Ar config-file
+Specify the pathname of the configuration file.
+For the
+.Fl C
+option, this file will be used to specify all configuration values.
+For the
+.Fl D
+and
+.Fl S
+options, this file will only be used to specify the name of the PF device.
+.Pp
+See
+.Xr iovctl.conf
+for a description of the config file format and documentation of the
+configuration parameters that apply to all PF drivers.
+See the PF driver manual page for configuration parameters specific to
+particular hardware.
+.It Fl n
+Perform a dry-run.
+Perform all validation of the specified action and print what would be done,
+but do not perform the actual creation or destruction of VFs.
+This option may not be used with the
+.Fl S
+flag.
+.It Fl S
+Read the configuration schema from the specified device and print its contents
+to stdout.
+This action may be used to discover the configuration parameters supported on
+a given PF device.

+.Sh NAME
+.Nm iovctl.conf
+.Nd IOVCTL configuration file
+.Sh DESCRIPTION
+The
+.Nm
+file is the configuration file for the
+.Xr iovctl 8
+program.
+This file specifies configuration parameters for a single Physical Function
+.Pq PF
+device.
+To configure SR-IOV on multiple PF devices, use one configuration file for each
+PF.
+The locations of all
+.Xr iovctl 9
+configuration files are specified in
+.Xr rc.conf 5 .
+.Pp
+The
+.Nm
+file uses UCL format.
+UCL syntax is documented at the official UCL website:
+http://github.com/vstakhov/libucl.
+.Pp
+There are three types of sections in the
+.Nm
+file.
+A section is a key at the top level of the file with a list as its value.
+The list may contain the keys specified in the
+.Sx OPTIONS
+section of this manual page.
+Individual PF driver implementations may specify additional device-specific
+configuration keys that they will accept.
+The order in which sections appear in
+.Nm
+is ignored.
+No two sections may have the same key.
+For example, two sections for VF-1 must not be defined.
+.Pp
+The first section type is the PF section.
+This section always has the key "PF"; therefore, only one such section may be
+defined.
+This section defines configuration parameters that apply to the PF as a whole.
+.Pp
+The second section type is the VF section.
+This section has the key "VF-" followed by a VF index.
+VF indices start at 0 and always increment by 1.
+Valid VF indices are in the range of 0 to
+.Pq num_vfs - 1 .
+The VF index must be given as a decimal integer with no leading zeros.
+This section defines configuration parameters that apply to a single VF.
+.Pp
+The third section type is the default section.
+This section always has the key "DEFAULT"; therefore, only one such section may
+be specified.
+This section defines default configuration parameters that apply to all VFs.
+All configuration keys that are valid to be applied to a VF are valid in this
+section.
+An individual VF section may override a default specified in this section by
+providing a different value for the configuration parameter.
+Note that the default section applies to ALL VFs.
+The default section must appear before any VF sections.
+The default section may appear before or after the PF section.
+.Pp
+The following option types are supported:
+.Bl -tag -width indent
+.It boolean
+Accepts a boolean value of true or false.
+.It mac-addr
+Accepts a unicast MAC address specified as a string of the form
+xx:xx:xx:xx:xx:xx, where xx is one or two hexadecimal digits.
+.It string
+Accepts any string value.
+.It uint8_t
+Accepts any integer in the range 0 to 255, inclusive.
+.It uint16_t
+Accepts any integer in the range 0 to 65535, inclusive.
+.It uint32_t
+Accepts any integer in the range 0 to
+.Pq 2**32 - 1 ,
+inclusive.
+.It uint64_t
+Accepts any integer in the range 0 to
+.Pq 2**64 - 1 ,
+inclusive.
+.El
+.Sh OPTIONS
+The following parameters are accepted by all PF drivers:
+.Bl -tag -width indent
+.It device Pq string
+This parameter specifies the name of the PF device.
+This parameter is required to be specified.
+.It num_vfs Pq uint16_t
+This parameter specifies the number of VF children to create.
+This parameter may not be zero.
+The maximum value of this parameter is device-specific.
+.El
+.Pp
+The following parameters are accepted by all VFs:
+.Bl -tag -width indent
+.It passthrough Pq boolean
+This parameter controls whether the VF is reserved for the use of the
+.Xr bhyve 8
+hypervisor as a PCI passthrough device.
+If this parameter is set to true, then the VF will be reserved as a PCI
+passthrough device and it will not be accessible from the host OS.
+The default value of this parameter is false.
+.El
+.Pp
+See the PF driver manual page for configuration parameters specific to
+particular hardware.
+.Sh EXAMPLES
+This sample file will create 3 VFs as children of the ix0 device.
+VF-1 and VF-2 are set as
+.Xr bhyve 8
+passthrough devices through the use of the default section.
+VF-0 is not configured as a passthrough device as it explicitly overrides the
+default.
+VF-0 also sets a device-specific parameter named mac-addr.
