Function Documentation

void NutLcpInput	(	NUTDEVICE *	dev,
		NETBUF *	nb
	)

Handle incoming LCP packets.

Packets not destined to us or packets with unsupported address type or item length are silently discarded.

Note:: This routine is called by the Ethernet layer on incoming ARP packets. Applications typically do not call this function.

Parameters:

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

int NutLcpOutput	(	NUTDEVICE *	dev,
		u_char	code,
		u_char	id,
		NETBUF *	nb
	)

Send a LCP packet.

Note:: Applications typically do not call this function.

Parameters:

	dev	Identifies the device to use.
	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.
