Function Documentation

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, u_char  code, u_char  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.
