A new tar-ball is provided with a solution to the previous assignment. If your solution is similar to the one presented, you may choose to continue on with it; but it is suggested that you untar the new project files in a fresh working directory:

Two parts of standard number 5 of the Internet Official Protocol Standards are the Internet Protocol (IP) and the Internet Control Message Protocol (ICMP). In this assignment students will build both IP and ICMP into Embedded Xinu.
Upon completion of the assignment the students' implementation should:
- send and receive packets of with type IP
- further demultiplex IP packets to find the underlying type
- send and receive ICMP packets
Upon completion of this assignment students should understand the key role this protocol plays in the overall networking architecture. Each student should be able to understand what an Internet Protocol address is and how the protocol uses this address to acquire a MAC address for the network packet before it can proceed through the system and be sent out over the network.
