void IpcpRxProtRej ( NUTDEVICE dev  ) 

void NutIpcpInput ( NUTDEVICE dev,
NETBUF nb 
)

Handle incoming IPCP 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 NutIpcpOutput ( NUTDEVICE dev,
uint8_t  code,
uint8_t  id,
NETBUF nb 
)

Send a IPCP 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.
