Handle incoming LCP packets.
Packets not destined to us or packets with unsupported address type or item length are silently discarded.
dev | Identifies the device that received the packet. | |
nb | Pointer to a network buffer structure containing the ARP packet. |

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. |
