00007  * Structure from acknowledgment of a routed frame looks like:
00008  *
00009  * BROADCAST MAC        // -> ff:ff:ff:ff:ff:ff                                 6Byte
00010  * SOURCE MAC           // MAC of the using interface                           6Byte
00011  * ETH TYPE FIELD       // 0x4148 (AH as string)                                2Byte
00012  * FRAME TYPE           // 0x41   (A as string)                                 1Byte
00013  * DESTINATION MAC      // next hop to forward the frame to the root source     6Byte
00014  * FRAME ID             // ID of the frame to acknowledge or packet id (if mc)  4Byte
00015  * ROUTE ID             // ID of the Route or packet sequence (if mc)           4Byte
00016  * FLAG FIELD                                                                   1Byte
00017  * SOURCE HOST LENGTH                                                           4Byte
00018  * SOURCE HOST                                                                  VAR
00019  * CRC                                                                          4Byte
00020  *
00021  * This frame type is used to acknowledge end-to-end routed frames
