-+/* NOTES
-+ * The instruction set of the 93C66/56/46/26/06 chips are as follows:
-+ *
-+ * Start OP *
-+ * Function Bit Code Address** Data Description
-+ * -------------------------------------------------------------------
-+ * READ 1 10 A7 - A0 Reads data stored in memory,
-+ * starting at specified address
-+ * EWEN 1 00 11XXXXXX Write enable must precede
-+ * all programming modes
-+ * ERASE 1 11 A7 - A0 Erase register A7A6A5A4A3A2A1A0
-+ * WRITE 1 01 A7 - A0 D15 - D0 Writes register
-+ * ERAL 1 00 10XXXXXX Erase all registers
-+ * WRAL 1 00 01XXXXXX D15 - D0 Writes to all registers
-+ * EWDS 1 00 00XXXXXX Disables all programming
-+ * instructions
-+ * *Note: A value of X for address is a don't care condition.
-+ * **Note: There are 8 address bits for the 93C56/66 chips unlike
-+ * the 93C46/26/06 chips which have 6 address bits.
-+ *
-+ * The 93Cx6 has a four wire interface: clock, chip select, data in, and
-+ * data out.While the ADM6996 uning three interface: clock, chip select,and data line.
-+ * The input and output are the same pin. ADM6996 can only recognize the write cmd.
-+ * In order to perform above functions, you need
-+ * 1. to enable the chip select .
-+ * 2. send one clock of dummy clock
-+ * 3. send start bit and opcode
-+ * 4. send 8 bits address and 16 bits data
-+ * 5. to disable the chip select.

-+* SL351x NAT Frames should meet the following conditions:
-+* 1. TCP or UDP frame
-+* 2. Cannot be special ALGs ports which TCP/UDP data is updated
-+* 3. LAN-IN Frames:
-+* Source IP is in the LAN subnet and Destination is not in the LAN subnet
-+* 4. WAN-IN Frames
-+* Destination IP is in the WAN port IP
-+*
-+* Example Ports
-+* 1. TCP/UDP data is updated
-+* (a) FTP Control Packet
-+* (b) VoIP Packets
-+* (c) etc. (add in future)
-+* 2. UDP Low packet rate, not worth
-+* (b) TFTP Destination Port is 69
-+* (b) DNS 53
