32 * "QSFP+ 10 Gbs 4X PLUGGABLE TRANSCEIVER" revision 4.8 dated October 31, 2013
34 * This SFF standard defines the following QSFP+ memory address module:
36 * 1) 256-byte addressable block and 128-byte pages
37 * 2) Lower 128-bytes addresses always refer to the same page
38 * 3) Upper address space may refer to different pages depending on
39 * "page select" byte value.
43 * Serial address 0xA02:
46 * 0-127 Monitoring data & page select byte
50 * 128-191 Base ID Fields
52 * 223-255 Vendor Specific ID
55 * 128-255 App-specific data
58 * 128-255 User EEPROM Data
60 * Page 03 (optional for Cable Assmeblies)
62 * 225-237 Vendor Specific
63 * 238-253 Channel Controls/Monitor
66 * All these values are read across an I2C (i squared C) bus.
