Parameters:

dev	Identifies the device that received the packet.
nb	Pointer to a network buffer structure containing the PAP packet.

int NutPapOutput	(	NUTDEVICE *	dev,
		uint8_t	code,
		uint8_t	id,
		NETBUF *	nb
	)

Send a PAP packet.

Note:

Applications typically do not call this function.

Parameters:

dev	Identifies the device to use.
code	Type subcode.
id	Exchange identifier.
nb	Network buffer structure containing the packet to send or null if the packet contains no information. The structure must have been allocated by a previous call NutNetBufAlloc() and will be freed when this function returns.

Returns:

0 on success, -1 in case of any errors.
