+ * P4 Calculator
+ *
+ * This program implements a simple protocol. It can be carried over Ethernet
+ * (Ethertype 0x1234).
+ *
+ * The Protocol header looks like this:
+ *
+ *        0                1                  2              3
+ * +----------------+----------------+----------------+---------------+
+ * |      P         |       4        |     Version    |     Op        |
+ * +----------------+----------------+----------------+---------------+
+ * |                              Operand A                           |
+ * +----------------+----------------+----------------+---------------+
+ * |                              Operand B                           |
+ * +----------------+----------------+----------------+---------------+
+ * |                              Result                              |
+ * +----------------+----------------+----------------+---------------+
+ *
+ * P is an ASCII Letter 'P' (0x50)
+ * 4 is an ASCII Letter '4' (0x34)
+ * Version is currently 0.1 (0x01)
+ * Op is an operation to Perform:
+ *   '+' (0x2b) Result = OperandA + OperandB
+ *   '-' (0x2d) Result = OperandA - OperandB
+ *   '&' (0x26) Result = OperandA & OperandB
+ *   '|' (0x7c) Result = OperandA | OperandB
+ *   '^' (0x5e) Result = OperandA ^ OperandB
+ *
+ * The device receives a packet, performs the requested operation, fills in the 
+ * result and sends the packet back out of the same port it came in on, while 
+ * swapping the source and destination addresses.
+ *
+ * If an unknown operation is specified or the header is not valid, the packet
+ * is dropped
