netdev_add_layer()

static netdev_t* netdev_add_layer ( netdev_t *  top, netdev_t *  dev  )

inlinestatic

Add a netdev layer to the netdev layer stack.

Parameters

[in]	top	Last netdev device added to the stack.
[in]	dev	New layer to push to the top of the stack.

Returns

The new top netdev layer of the netdev stack.

netdev_event_cb_pass()

void netdev_event_cb_pass	(	netdev_t *	dev,
		netdev_event_t	event
	)

Passthrough event callback function.

Parameters

[in]	dev	network device descriptor
[in]	event	type of the event

netdev_get_pass()

int netdev_get_pass	(	netdev_t *	dev,
		netopt_t	opt,
		void *	value,
		size_t	max_len
	)

Passthrough get function.

See also netdev_driver for the extended description of this functions behaviour

Parameters

[in]	dev	network device descriptor
[in]	opt	option type
[out]	value	pointer to store the option's value in
[in]	max_len	maximal amount of byte that fit into value

Returns

number of bytes written to value

< 0 on error, 0 on success

netdev_init_pass()

int netdev_init_pass

(

netdev_t *

dev

)

Passthrough init function.

See also netdev_driver for the extended description of this functions behaviour

Parameters

[in]

dev

network device descriptor

Returns

< 0 on error, 0 on success

netdev_isr_pass()

void netdev_isr_pass

(

netdev_t *

dev

)

Passthrough isr function.

See also netdev_driver for the extended description of this functions behaviour

Parameters

[in]

dev

network device descriptor

netdev_recv_pass()

int netdev_recv_pass	(	netdev_t *	dev,
		void *	buf,
		size_t	len,
		void *	info
	)

Passthrough recv function.

See also netdev_driver for the extended description of this functions behaviour

Parameters

[in]	dev	network device descriptor
[out]	buf	buffer to write into or NULL
[in]	len	maximum number of bytes to read
[out]	info	status information for the received packet. Might be of different type for different netdev devices. May be NULL if not needed or applicable.

Returns

< 0 on error

number of bytes read if buf != NULL

packet size if buf == NULL

netdev_send_pass()

int netdev_send_pass	(	netdev_t *	dev,
		const iolist_t *	iolist
	)

Passthrough send function.

See also netdev_driver for the extended description of this functions behaviour

Parameters

[in]	dev	network device descriptor
[in]	iolist	io vector list to send

Returns

number of bytes sent, or < 0 on error

netdev_set_pass()

int netdev_set_pass	(	netdev_t *	dev,
		netopt_t	opt,
		const void *	value,
		size_t	value_len
	)

Passthrough set function.

See also netdev_driver for the extended description of this functions behaviour

Parameters

[in]	dev	network device descriptor
[in]	opt	option type
[in]	value	value to set
[in]	value_len	the length of value

Returns

number of bytes used from value

< 0 on error, 0 on success
